## Background
CROSS-REFERENCES TO RELATED APPLICATIONS
The present invention is related to and incorporates by reference for all purposes U.S. patent application Ser. No. 10/841,804, filed May 6, 2004, titled Integrated Object Bend, Squash and Stretch Method and Apparatus.
BACKGROUND OF THE INVENTION
The present invention relates to computer animation. More specifically, the present invention relates to enhanced user interfaces for object creation and animation.
Throughout the years, movie makers have often tried to tell stories involving make-believe creatures, far away places, and fantastic things. To do so, they have often relied on animation techniques to bring the make-believe to “life.” Two of the major paths in animation have traditionally included, drawing-based animation techniques and stop motion animation techniques.
Drawing-based animation techniques were refined in the twentieth century, by movie makers such as Walt Disney and used in movies such as “Snow White and the Seven Dwarfs” (1937) and “Fantasia” (1940). This animation technique typically required artists to hand-draw (or paint) animated images onto a transparent media or cels. After painting, each cel would then be captured or recorded onto film as one or more frames in a movie.
Stop motion-based animation techniques typically required the construction of miniature sets, props, and characters. The filmmakers would construct the sets, add props, and position the miniature characters in a pose. After the animator was happy with how everything was arranged, one or more frames of film would be taken of that specific arrangement. Stop motion animation techniques were developed by movie makers such as Willis O'Brien for movies such as “King Kong” (1933). Subsequently, these techniques were refined by animators such as Ray Harryhausen for movies including “Mighty Joe Young” (1948) and Clash Of The Titans (1981).
With the wide-spread availability of computers in the later part of the twentieth century, animators began to rely upon computers to assist in the animation process. This included using computers to facilitate drawing-based animation, for example, by painting images, by generating in-between images (“tweening”), and the like. This also included using computers to augment stop motion animation techniques. For example, physical models could be represented by virtual models in computer memory, and manipulated.
One of the pioneering companies in the computer aided animation (CAA) industry was Pixar, dba Pixar Animation Studios. Over the years, Pixar developed and offered both computing platforms specially designed for CAA, and Academy-Award® winning rendering software known as RenderMan®.
Over the years, Pixar has also developed software products and software environments for internal use allowing users (modelers) to easily define object rigs and allowing users (animators) to easily animate the object rigs. Based upon such real-world experience, the inventors of the present invention have determined that additional features could be provided to such products and environments to facilitate the object definition and animation process. One such feature includes methods and apparatus for facilitating the definition of custom toolbars according to individual user preference.
The inventors of the present invention recognize that many software packages provide a method for users to define a customize display of operational controls via a “toolbar” mechanism. As is known, toolbars are typically a collection of commands, actions and/or functions that are displayed to the user in a separate window on a computer display. To customize such toolbars, the inventors have determined that many packages require a user to work in an highly disruptive way to add commands to a toolbar. For example, in the Microsoft Word program, a user selects from the main application menu bar the “View” drop-down menu, select the “toolbars” drop-down menu, and then selects the “customize” button. After this, a dialog window provides the user with a scrolling list of the possible system commands. To add a command to a toolbar, the user drags the command from the list and on to the toolbar to be customized. After this, the user manually closes the dialog window, for example, with a left mouse button click.
FIGS. 1A-B illustrate a typical process for customizing a toolbar. For example, in a toolbar 100, icons 110 typically do not represent the functionality required by a user. Accordingly, to add the functionality to the toolbar, users open the dialog box or function window via the drop-down menu. As illustrated in the example in FIG. 1A, a customization dialog 120 is presented to the user. Next, the user selects a command from list 130, and drags it to a particular location on toolbar 100. As illustrated in FIG. 1B, in response to the customization, toolbar 100 will then include the requested icon 140 and functionality. Finally, the user manually clicks on button 150 using a left mouse button, for example, to close the open dialog box.
The inventors of the present application have discovered that these methods are very inefficient for object animators and object modelers and for any users who need to frequently change the function of the toolbar. Although these method for customizing a toolbar may be adequate for most users, in the present applications, because the users change tasks and modes frequently, these customization methods are highly disruptive. As illustrated, each time a function needs to be added to a toolbar, the user must leave the primary work space, navigate to the menu structure, open a customization window on top of the primary work space, perform the customization, save the customization, select the added function on the toolbar, then manually close the customization window on top of their primary work space.
FIGS. 2A-B illustrate a compressed toolbar example. FIG. 2A illustrates a toolbar 200 for a conventional drawing program. In this example, when a user clicks upon an icon location 210 using a right mouse button, for example, functions/icons 220 that share the same icon location 210 are displayed to the user, as illustrated in FIG. 2B. Next, the user clicks upon one of icons 220 using a left mouse button, for example, to select that icon for icon location 210 on toolbar 200. After selection of one of icons 220, that icon replaces the icon originally displayed.
The compressed toolbar is used to save screen space. In this example, if toolbar 200 were enlarged to show all the “sub-icons” that are selectable at all of the icon locations, toolbar 200 would take up a large portion of the screen. Accordingly, by having one icon location 210 associated with several pre-defined icons 220, toolbar 200 is thus compressed.
Drawbacks to the compressed toolbar technique include that a user is limited to the pre-defined functions (“sub-icons”) associated with each icon location. Another drawback is that the pre-defined functions can only be selected from particular icon locations. For instance, icon location 210 may represent a pencil function. In FIG. 2B, when icon location 210 is expanded, pre-defined functions are illustrated, such as pencil drawing, pen drawing, and eraser. These pre-defined functions are fixed and only available when the user selects icon location 210 in the toolbar. Another drawback is that, the user has to give-up one function (icon) in order to add another function (icon). For example, the only way to add an eraser function (icon) to the toolbar is to lose a pencil function (icon) from the toolbar. Further, to add the pencil function, the toolbar loses the eraser function. Accordingly, the compressed toolbar technique has significant drawbacks.
In light of the above, the inventors of the present invention have determined that improved methods for adding functionality to toolbars are needed without the drawbacks illustrated above.
BRIEF SUMMARY OF THE INVENTION
The present invention relates to computer animation. More specifically, the present invention relates to enhanced user interfaces for object creation and animation.

Network interface 350 are typically coupled to a computer network as shown. In other embodiments, network interface 350 may be physically integrated on the motherboard of computer 320, may be a software program, such as soft DSL, or the like.
Computer 320 typically includes familiar computer components such as a processor 360, and memory storage devices, such as a random access memory (RAM) 370, disk drives 380, and system bus 390 interconnecting the above components.
In one embodiment, computer 320 is a PC compatible computer having one or more microprocessors such as PentiumIVTM or XeonTM microprocessors from Intel Corporation. Further, in the present embodiment, computer 320 typically includes a LINUX-based operating system.
RAM 370 and disk drive 380 are examples of tangible media for storage of data, audio/video files, computer programs, scene descriptor files, object data files, shader descriptors, a rendering engine, output image files, texture maps, displacement maps, object creation environments, animation environments, asset management systems, databases and database management systems, and the like.

FIG. 4 illustrates a block diagram of an embodiment of the present invention. Specifically, FIG. 4 illustrates an animation environment 400, an object creation environment 410, and a storage system 420.
In the present embodiment, object creation environment 410 is an environment that allows users (modellers) to specify object articulation models, including armatures and rigs. Within this environment, users can create models (manually, procedurally, etc.) of objects and specify how the objects articulate with respect to animation variables (Avars). In one specific embodiment, object creation environment 410 is a Pixar proprietary object creation environment known as “Gepetto.” In other embodiments, other types of object creation environments can be used.
In the present embodiment, the object models that are created with object creation environment 410 may be used in animation environment 400. Typically, object models are heirarchically built. The heirarchical nature for building-up object models is useful because different users (modellers) are typically assigned the tasks of creating the different models. For example, one modeller is assigned the task of creating a hand model, a different modeller is assigned the task of creating a lower arm model, and the like. Accordingly, by dividing-up the responsibility for object creation, the object creation process time is greatly reduced.
In the present embodiment, animation environment 400 is an environment that allows users (animators) to manipulate object articulation models, via the animation variables (Avars). In one embodiment, animation environment 400 is a Pixar proprietary animation enviroment known as “Menv,” although in other embodiments, other animation environments could also be adapted. In this embodiment, animation environment 400 allows an animator to manipulate the Avars provided in the object models (generic rigs) and to move the objects with respect to time, i.e. animate an object.
In other embodiments of the present invention, animation environment 400 and object cration environment 410 may be combined into a single integrated environment.
In FIG. 4, storage system 420 may include any organized and repeatable way to access object articulation models. For example, in one embodiment, storage system 420 includes a simple flat-directory structure on local drive or network drive; in other embodiments, storage system 420 may be an asset management system or a database access system tied to a database, or the like. In one embodiment, storage system 420 receives references to object models from animation environment 400 and object creation environment 410. In return, storage system 420 provides the object model stored therein. As illustrated, object models typically specify one or more animation variables 430. In response, via animation environment 400, the user may specify values 440 for animation variables 430 either graphically, via keyboard, or the like.
FIG. 5 is a block diagram according an embodiment of the present invention. Initially, a user invokes a working environment, step 500. Embodiments of the present invention are implemented in Pixar's animation environment 400 called Menv and Pixar's object creation environment 410 called Gepetto. However, in light of the present disclosure, the inventors can foresee embodiments of the present invention being applied to virtually any program where toolbars and menus are customized by users. For example, embodiments maybe used in Microsoft Office products, Adobe products, and the like, to greatly enhance the process of customization.
Next, an initial toolbar is presented to the user, step 510. In one embodiment, an initial toolbar may be a default or pre-defined toolbar provided by the working environment or program. In another embodiment, the initial toolbar may include one or more toolbars specified by the user. These toolbars may have been previously customized and saved by the user.
In the present embodiment, to add functionality to an initial toolbar, the user positions a cursor above the initial toolbar, step 520, and presses the left button (selection button) on their mouse, step 530. In some embodiments, the users presses and holds the selection button (e.g. the left mouse button) down until released in step 560 below. In other embodiments, other methods for user selection are contemplated, for example, double clicking a barrel button or a tip button on a stylus, clicking a right mouse (non-selection button) button, clicking a non-selection button of another graphical input device, making a gesture, and the like.
In other embodiments, different methods for performing the functions of steps 520 and 530 are contemplated. For example, speaking a voice command, typing a hotkey or a key combination on a keyboard, using “sticky” keys and the like.
In embodiments of the present invention, in response to the selection in step 530, a list or menu of user selectable commands is presented to the user, step 540. The commands may have text labels, may have icons, or combinations thereof. In one embodiment, the list may be a horizontal row of selectable icons, a vertical column of selectable icons, an array of selectable icons, or the like. In one embodiment, the commands presented in the list may be a universe of commands provided by the software environment. In another embodiment, the commands presented in the list may be reduced by a user to commands the user wishes, e.g. only 40 commands not 300. As an example, the user may perform a certain group of commands (e.g. 12 commands) repeatedly, however, the number of icons that would be required exceed the toolbar space desired by the user (e.g. 8 toolbar slots). Accordingly, in one embodiment, the user specifies the group of commands (e.g. 12) that pops up on the display in this step in response to the selection in step 530.
In another embodiment, the commands that are presented to the user may be partially context sensitive, based upon the type of objects the user is working on. For example, if an object has an “integrated squash and stretch with volume preservation mode,” as described in above-referenced co-pending U.S. patent application, the “integrated squash and stretch with volume preservation” tool button will be displayed on the menu; if the object does not have the feature, the tool button will not be displayed. As another example, direct-manipulation bend and bow functionality, described in the above U.S. application, may or may not be supported by objects the user is working on. Accordingly, when the object supports the direct-manipulation bend and bow functionality, the menu may include a “direct-manipulation bend and bow” tool button. As additional examples, for specific items in a scene, including controls for props, lights, and the like, the list of commands presented to the user may vary. For example, when the user selects a light model in a scene, commands that may be added to a toolbar may include: cut-on, cut-off, barn door, drag light, intensity, frustum length, fall-off, diffuse, specular, rim, and the like, which are very light model specific.
In other embodiments, the principles may also apply to more conventional two-dimensional environments. For example, if there are multiple overlapping objects, commands or icons that may automatically be included in the pop-up list may include ordering commands, such as “bring to front,” “send to back,” “up one level,” “down one level,” and the like may appear. In such examples, if there is a single object or if objects are not overlapping, the ordering commands may not appear. As an additional example, if multiple objects are present in the scene, commands that may automatically be included include distribution commands (e.g. “evenly distribute,” “place adjacent.” and the like). When there is a single object, the distribution commands may be suppressed.
In other embodiments, if there are multiple objects with objects including some unique modes, the list of user selectable commands may be the union of the modes of the multiple objects. For example, if a first object in a scene has an integrated squash and stretch with volume preservation mode, and a second object in a scene has a direct-manipulation bend and bow mode, the menu displayed to the user will have tool buttons representing the both the manipulation modes.
In still other embodiments, different ways to dynamically determine the commands that are in the pop-up menu are contemplated based upon the user's preferences, based upon the type of objects currently in the working environment, the frequency of usage, and the like. In other embodiments, the user may query for what modes are available for objects in a scene, or the like.
In some embodiments, the user then moves the cursor over one command from the list of user selectable commands the user wishes to add to the toolbar, step 540. In some embodiments, this occurs while the mouse button is still depressed. In other embodiments, the user may use arrow keys on a keyboard, or the like to select the command from the list.
In embodiments of the present invention, a hierarchical structure may be added to the list of user selectable commands. For example, the menu or list of user commands in the pop-up menu may initially have categories of commands. When the user moves the cursor over one command category, an additional pop-up menu appears that includes additional user selectable commands that are within the command category. In such embodiments, the user can navigate up and down the hierarchical command structure by simply moving the cursor over the desired command categories. In some embodiments of the present invention, these pop-up menus and sub-menus, etc. are also ephemeral, i.e. they automatically close after the user moves-off the list of user selectable commands. Additionally, they also automatically close after the user makes a selection in the following step.
In the example in FIG. 5, the user next makes a selection of the command to add to the toolbar, step 560. In one embodiment, the user presses and holds a mouse button down, such as the left mouse button (selection button) to view the list of user selectable commands in step 530. The user then navigates to the command they wish to add, and then the user releases the mouse button to make the selection. In other embodiments, to select the command, the user may do so in any number of conventional methods, such as clicking a button on a user input device, striking a key on a keyboard, speaking a voice command, and the like.
Next, the selected command is added to the toolbar, step 570. In embodiments of the present invention, an icon or text button associated with the command is added to an empty location on the toolbar. In some embodiments, the toolbars may include as many icons as desired. In other embodiments, a limited number of spaces are specified, accordingly, if the toolbar does not have an empty location, another icon may be “bumped” from the toolbar. The determination of which icon is bumped may be based upon frequency of usage of icons in the toolbar, user selection, or the like. In embodiments of the present invention, the pop-up list of commands is automatically removed from the display after the user makes the selection. Accordingly, the user does not have to specifically select an “ok” button, or the like.
In embodiments of the present invention, the user may give customized toolbars names and save and recall the icons included in the toolbars. It is contemplated that different users will have different icons, depending upon the user's requirements, the objects in the scene, and the like. In other embodiments, toolbars may be customized for users within a common working groups, organization, or the like. Additionally, sub-sets of toolbars may also be saved and recalled. For example, a set of icons related to a particular character, such as “Helen” controls may also be saved and reused. The icons may include character specific functionality, such as “integrated stretch and squash with volume preservation” functionality. In other examples, sets of icons related to “hand” controls, “bi-pedal” character controls, and the like may be saved and reused; and the like. Toolbars, and the like may also be “rolled-up” and “torn away” on the graphical user interface.
FIGS. 6A-F illustrate graphical user interfaces according to embodiments of the present invention. In some embodiments of the present the graphical user interface 600 is a user interface within animation environment 400 and/or object creation environment 410, or the like.
In FIG. 6A, a number of functional object “modes” are illustrated. Within the environments above, users (e.g. animators, modelers) often select different modes to manipulate the object models (e.g. rigs) or to view the models in different ways. In the example in FIG. 6, a toolbar 600 includes a number of locations 620 including icons that allow users to execute the functions specified on the object. In this example, the modes include a pick mode (e.g. for selecting objects), a translate mode (e.g. for moving objects), rotate mode (e.g. for rotating the objects) at location 610, a scale mode (e.g. for changing the scale of objects), and a grouping mode 625 (e.g. for allowing manipulation of a group of objects). In various embodiments, other modes are contemplated such as a jiggle mode, integrated squash and stretch with volume preservation mode, direct-manipulation object bend and bow mode, and the like.
Additionally, toolbar 600 includes user-selectable region 630. In the present embodiment, users can invoke commands by selecting an icon or text displayed in toolbar 600 in any conventional way, such as a left-button mouse click (selection button). In other embodiments, toolbars are directly mapped to keys on a keyboard. As an example, icons on a toolbar may be arranged horizontally across the screen, and selection of one of the QWERTY keys on the keyboard automatically invoke a corresponding mode.
In FIG. 6B, the user has positioned a cursor 635 over user-selectable region 630 on toolbar 600 and depressed the left mouse button (selection button). In response, according to one embodiment, a list 640 of user selectable commands or icons are presented to the user. In this case, list 640 is a list of all assignable mode commands for the scene. In the present example, the list is generated by the system generating a query of the all of the models in a “shot” (series of related images) and collating the intersection of all possible modes. In some embodiments, the icons displayed in list 640 may be set or pre-defined by the user, may be dynamically determined based upon data in the “shot,” based upon frequency of usage, or the like.
In FIG. 6B, the user has moved cursor 635 on top of icon 650, representing an integrated squash and stretch with volume preservation mode. In the present example, when the user releases the selection button, icon 650 will be added to toolbar 600. In other embodiments, other methods for selecting icon 640 are contemplated, for example, via arrow keys and other keyboard input, voice command, additional right or left button mouse clicks, and the like.
In the example in FIG. 6C, the user has added two mode commands to toolbar 600 using the disclosed techniques to form toolbar 660. Specifically, as can be seen, the user has added icon 670, representing an integrated squash and stretch with volume preservation command, and icon 680, representing a direct-manipulation bend and bow command.
In some embodiments, if a cursor is positioned over a specific location in toolbar 600, such as location 610, when the process described above is performed, a user-selected icon may replace the icon already at location 610. More specifically, FIG. 6D illustrates an example where a list 690 of user selectable commands are presented to the user while cursor 700 is positioned at location 610 (FIG. 6A) in toolbar 600 and depresses the (left) selection button, or the like. Next, when the user releases the (left) selection button while cursor 700 is positioned over icon 705, the “send to back” mode then replaces the rotate mode icon in the resulting menu 710 as can be seen in FIG. 6E.
In other embodiments of the present invention, icons added to a menu may replace existing icons, may be inserted between existing icons, may be inserted before or after existing icons, or the like. For example, in FIG. 6E, a toolbar 715 is illustrated. In this example, compared to toolbar 600 in FIG. 6A, icon 720 replaces the existing rotate icon in location 610, icons 730 were added before existing icon 740, and icons 750 were added after existing icon 740.
In embodiments of the present invention, particular icons may have restricted properties. For example, in FIG. 6A, the icon 625 on toolbar 600 is a Group Mode command (e.g. a specification for a mode that allows the user to treat multiple objects as a group—rather than as a collection of individuals for functions such as rotations, scales, and the like.)
In various embodiments, certain icons may not be removed from toolbar 600 and are a persistent part of Direct Manipulation toolbar 600. In other embodiments, restrictions may also be placed on icon positions. For example, in various embodiments, icon 625 is always at a particular location in toolbar 600, such as the last mode button on toolbar 600; a pick command is always at the first slot of toolbar 600, or the like. In other embodiments, other types of restrictions on icons are contemplated. In embodiments of the present invention, the restrictions on icons may be set by a programmer, by the user, or the like.
In embodiments of the present invention, users can set the maximum number of icons that are displayed on the toolbar at a time. Additionally, toolbars can be resized, the shaped changed (i.e. row of icons to grid of icons, using conventional window drag techniques, torn off, and the like.
Using the embodiments described above, users at Pixar can easily define and redefine toolbar functionality. Within Pixar, users have anecdotally noticed an increase in productivity within software environments using embodiments of the present invention.
Many changes or modifications are readily envisioned. In light of the above disclosure, one of ordinary skill in the art would recognize that the concepts described above may be applied to any number of environment. For example, the toolbar concepts may be applied to any number of software programs where customization and addition of icons to toolbars is desired. Other combinations of embodiments are also contemplated.
In embodiments of the present invention, various methods for initiating the process and selecting commands is contemplated, for example, hotkeys may be associated with individual slots of a toolbar to increase the speed at which a user can switch between the modes. Hotkeys may also be associated with particular user commands, and the like. Additionally, Hotkeys may be assigned to hide toolbars, resize toolbars, revert toolbars, and the like. In embodiments of the present invention, users can name and save toolbar configurations for later use. Access to saved toolbars may be provided via pull-down menu, or other conventional technique.
In embodiments of the present invention, reference has been made to a “selection” button of a mouse. The selection button may vary in actual implementation.
