I recently got a file describing a library of rendering routines  called SIPP (SImple Polygon Processor).  Could anyone tell me where I can  FTP the source code and which is the newest version around?         Also, I've never used Renderman so I was wondering if Renderman  is like SIPP?  ie. a library of rendering routines which one uses to make  a program that creates the image...                                          Thanks,  Joe Tham

How much do C libraries cost anyway?  Can you get the tools used by, say, RenderMan, and can you get them at a reasonable cost?  Sorry that I don't have any answers, just questions...
Hello,  I am interested to hear from people working in the field of visual simulation, ie driving simulation, flight simulation etc. Would be very pleased to see, what is going on in the field of research and industrial development.  For those of you interested as well: There is a workshop (preferedly  held in German), situated in Wuppertal, November 18/19 1993, specially related to the above topic. The title:  "Sichtsysteme - Visualisierung in der Simulationstechnik"  Complete details are available. Please contact me.

I'm >philosophically< opposed to it because of its complexity.  This complexity has led to some programs' poor TIFF writers making some very bizarre files, other programs' inability to load TIFF images (though they'll save them, of course), and a general inability to interchange images between different environments despite the fact they all think they understand TIFF.  As the saying goes, "It's not me I'm worried about- it's all the >other<  assholes out there!"  I've had big trouble with misuse and abuse of TIFF over the years, and I chalk it all up to the immense (and unnecessary) complexity of the format.  In the words of the TIFF 5.0 spec, Appendix G, page G-1 (capitalized emphasis mine):  "The only problem with this sort of success is that TIFF was designed to be powerful and flexible, at the expense of simplicity.  It takes a fair amount of effort to handle all the options currently defined in this specification (PROBABLY NO APPLICATION DOES A COMPLETE JOB), and that is currently the only way you can be >sure< that you will be able to import any TIFF image, since there are so many image-generating applications out there now."   If a program (or worse all applications) can't read >every< TIFF image, that means there are some it won't- some that I might have to deal with.  Why would I want my images to be trapped in that format?  I don't and neither should anyone who agrees with my reasoning- not that anyone does, of course! :-)

What I mean by "compositing" is, say I have a live video clip    (digitized) panning around a living room, and a computer-generated    bird flying around the screen.  I want to combine these two series of    pictures so that everywhere where the bird frames are black, I want    the living room picture to show through.  Yes, I realize I can do this    with a genlock, and I do own a genlock, but I want to be able to do    manual compositing also.  It's ok if I have to composite one frame at    a time; I assumed I'd have to do that anyway.  But being able to    composite a series of frames would be even better.     I've looked around and I haven't found a PC package that will perform    this.  Help, please!  If you can get the live animation and the computer-generated animation into AutoDesk Animator .FLI or .FLC format, AutoDesk Animator will do this for you.  It can take one animation, make a certain color "clear", and overlay it over another animation.  I do not have a way right now to convert .AVI or .MPG files to animator files.  Animator will also import a series of .GIF files to create an animation, so if your video capture stuff can create this is might work.

The first one is Ray (or half line) method. In this method, you can draw any ray, if the number of the intersection point of the ray and the polygon is even, then it is outside. If the number is odd, then it is inside. Of cause, you have to deal with the special cases which may make you headache.  The second method is PI algorithm. Draw the lines between the point and all the vertices on the polygon. Calculate and sum the angles of the successive lines. If the result is 2*PI, then it is inside. If PI, then it is on the polygon. Otherwise it is outside.  My experience tells the second method is relible.  Hope this helps.

Most JPEG viewers seem to require specific video drivers since they support only specific video cards. Some have the standard IBM BIOS video support for the VGA 320x200 256 colour mode, but they leave out the other cards such as the Hercules monochrome card (which by the way can give very good picture quality if your dithering works right).  I can't remember the name of a JPEG viewer since I usually convert JPEG's to GIF's before viewing them. But some require VESA driver for the video cards. You don't need any special hardware to view JPEG's except perhaps for a VGA card and maybe a 286+ processor. Most people these days program for 286+ computers and neglect the rest of the 86 processors (8086, 8088). I have a 8088 clone (a NEC V20 processor) and a Hercules card, I have had to write some programs so that they will view GIF's and animations for the VGA and other colour graphics boards on my monochrome Hercules card. I use Floyd-Steinberg dithers and have found that if one does something neat with the colour palette the resulting dithered image gives much greater detail than it normally would when viewed on other monochrome systems. CompuShow 8.50 has FS dithering but it does the standard thing with the image palette before dithering, my way gives a brighter more detailed image.  Anyway, enough of my rambling in the wrong direction. The final point is, as far as I know, you don't need extra hardware to view JPEG's other than the VGA (and perhaps a 286 or better)  Have a day!

Do an intersection calculation in the plane in 2D, where you're guaranteed a unique solution (unless they're parallel which won't happen in this case), and then use parametric distance along the lines from the circle centres to determine the exact point of interest.  This bypasses the messy error propogation required to do the calculation in 3d.  Hope I haven't put my foot in it again!  steve ---

Rather than decide which book you want to buy, you need to decide which programming interface you want to use, then buy the appropriate book.  I wrote an article for the X Resource which discusses the differences between PHIGS and PEXlib (it will appear in Issue 6 which should be out pretty soon).  But here's a brief summary...  PHIGS is a graphics API which was designed to be portable to many devices.  Most implementations support the X Window System and take advantage of a 3D extension to X called "PEX".  PEXlib is a slightly "lower" level API which was designed to efficiently support the PEX extension to X.  Some advantages of using PEXlib... - Integrates with Xlib,Xt,Motif,etc. better than PHIGS - Provides immediate mode capabilities - Is free of "policy" - PEX supports PHIGS, but is currently being extended to support   features not found in PHIGS (like texture mapping, anti-aliasing).   PEXlib will give you access to all of these features.  Some advantages of using PHIGS... - Support for multiple devices, not just X based ones - Support for archiving, metafiles, hardcopy output - PHIGS has predefined input devices to make input easier - PHIGS can handle exposure events and resizing for you - PHIGS can help you with colormap selection/creation.  If you're working strictly in X and don't care about things like archiving, I would go with PEXlib.  Either way, you will find that both API's have a lot in common.
I need information on the Display PostScript strokeadjust feature. This feature adjusts the endpoints of lines so that the displayed line looks better on low resolution devices.  The PostScript literature explains the process to some extent.  They also give an example of how to "emulate" strokeadjust in PostScript environments where it is absent.  The suggested emulation is to modify the coordinates of the endpoints of a line using the following formula for each coordinate:  	new_coord = (round (old_coord - 0.25)) + 0.25 	 Doing this we end up with all coordinates ending in ".25".  From reading I thought that what they might actually do is:  	new_coord = ((trunc (old_coord * 2)) / 2) + 0.25 	 This results in all the coordinates ending in either "0.25" or "0.75"  whichever is closer.  By doing some actual comparisons with Display PostScript, I find that neither of these is what DPS really uses.  Since I like how the DPS result looks better than how my stuff looks, I'd like to know if anyone who knows how DPS does it is willing/able to tell me.  Thanks,
