Abstract:
A method of controlling an animation in a three dimensional virtual environment, the method comprising the steps of:creating an animation wherein the animation includes geometry to be animated;creating a parent transform for the animation such that the parent transform repositions the geometry of the animation to provide a predefined point of view to a user;determining a position of a user in the three dimensional virtual environment; andutilizing the parent transform to transform the animation to maintain the predefined point of view to the user based upon the position of the user in the three dimensional environment; andwherein said creating an animation step comprises creating an animation by associating a VRML Timesensor and a VRML Coordinatelnterpolator with the geometry to be animated; andwherein said creating a parent transform step comprises the step of creating a parent transform for the animation such that the parent transform repositions the VRML Coordinatelnterpolator and VRML Timesensor to provide the predefined point of view to a user.
