Hi all.  I'm looking for datasets of a human body or head  in any of the popular formats.  I'm doing a presentation tomorrow which could be greatly enhanced by bringing in this 'human' factor.  I've looked around the net with no sucess so far.  Anyone got any ideas? I'd also appreciate info on the location of datasets for the USS Enterprise (any model) Thanks in advance, Ronan

Okay all my friends are bitching at me that the map I made in Appsoft Draw can't be displayed in "xv"... I checked... It's true, at least with version 1.0.  My readers on the NeXT have very little trouble on it (Preview messes up the .eps, but does fine with the TIFF and ImageViewer0.9a behaves with flying colors except it doesn't convert worth *&^^% ;-) )    Please is there any way I can convert this .drw from Appsoft 1.0 on the NeXT to something more reasonable like .gif?  I have access to a sun4 and NeXTstep 3.0 systems.  any good reliable conversion programs would be helpful... please email, I'll post responses if anyone wants me to... please email that to.  Yes I used alphachannel... (god i could choke steve jobs right now ;-) )  Yes i know how to archie, but tell me what to archie for ;-)  Also is there a way to convert to .ps plain format?

I am looking for some information about 3D animation stations that are currently on the market.  The price of the station can be from 5K-20K,  but no more than $20,000.00.  Type of workstation doesnt matter (PC, MAC,  SGI etc..) .  If you use or have bought/looked at one or can suggest your dream machine, then please mail me your configurations.  I need the following.  	1. Type of station (PC, MAC etc.. ) 	2. Expandibilty of the machine. 	3. Software that can run on it 	4. VTR Controller and/or VTR deck model/name. 	5. Vendors names and numbers.  Thanks in advance.
Hi! Everyone,  Since some people quickly solved the problem of determining a sphere from 4 points, I suddenly recalled a problem which is how to find the ellipse from its offset. For example, given 5 points on the offset, can you find the original ellipse analytically?  I spent two months solving this problem by using analytical method last year, but I failed. Under the pressure, I had to use other method - nonlinear programming technique to deal with this problem approximately.  Any ideas will be greatly appreciated. Please post here, let the others share our interests.
Help!! I need code/package/whatever to take 3-D data and turn it into a wireframe surface with hidden lines removed. I'm using a DOS machine, and the code can be in ANSI C or C++, ANSI Fortran or Basic. The data I'm using forms a rectangular grid.    Please post your replies to the net so that others may benefit. IMHO, this is a general interest question.    Thank you!!!!!!
Hello everybody !  If you are using PIXAR'S RenderMan 3D scene description language for creating 3D worlds, please, help me.   I'm using RenderMan library on my NeXT but there is no documentation about NeXTSTEP version of RenderMan available. I can create very complicated scenes and render them using surface shaders,  but I can not bring them to life by applying shadows and reflections.  As far as I understand I have to define environmental and shadows maps to produce reflections and shadows, but I do not know how to use them.  Any advises or simple RIB or C examples will be appreciated. Thanks in advance...
Using the VMODE command, all you need to do is type VMODE VESA at the dos prompt. VMODE is included with the Speedstar 24.  I have used the VESA mode for autodesk animator pro.
A good reason (which is why many companies use it) for 48 bits / pixel is so you can use double buffering (for animating scenes) - i.e. you have 2 * 24-bit planes. You write to the one in the background, and then FLIP!  -- the entire screen updates to the second image-plane. The screen updates  in one refresh and you don't see different objects appearing in the order  that they're drawn (as in the CAD/MacDraw effect). Now your ready to update  the image that used to be in the foreground.  Steve. (thssstb@iitmax.iit.edu / iris.iit.edu)

Hello,  	Does anyone know of an image format conversion tool that will convert a  raw (8 bit grey scale) image to Gif or Tif format.  It would be great if the tool ran on a PC, was a Windows application, and supported other formats, but I'll be  happy with anything that works.

Hello there!  A week ago a guy asked what a .SCO file was - well I researched a bit and foundout that it is just another RIX file. .SCI files are 320x200 files and .SCO files are 1024x768 files! alle the other formats (800x600, 640x480...) are also called something like .SC(character).
Hello netters!   I have a fairly weak question to ask everybody in netland.  I've looked though the last FAQ for comp.graphics but I didn't find my answer.  Thus the post.   I'll keep it short.   QUESTION:  How do I display any raster files, gif files, iff or tiff images that I have on my "root window" or background?  I have a sun ipc, openwindows 3.0, Sun OS 4.1.3 if that helps any.   I've compiled POV for the sun and would like to display some of the work I have done as a background/tile.  Thanks for any help or information that you provide.  Have a good day.   Scott Fleming OSI

G'day all,  Can anybody point me at a utility which will read/convert/crop/whatnot/ display HDF image files ? I've had a look at the HDF stuff under NCSA  and it must take an award for odd directory structure, strange storage approaches and minimalist documentation :-)  Part of the problem is that I want to look at large (5MB+) HDF files and crop out a section. Ideally I would like a hdftoppm type of utility, from which I can then use the PBMplus stuff quite merrily. I can convert the cropped part into another format for viewing/animation.  Otherwise, can someone please explain how to set up the NCSA Visualisation S/W for HDF (3.2.r5 or 3.3beta) and do the above cropping/etc. This is for Suns with SunOS 4.1.2.  Any help GREATLY appreciated. Ta muchly !

I'm looking for code that will generate a minimum-volume oriented bounding box for an arbitrary polyhedron.  Anyone know of such code?         Why?  I'm converting objects from one modelling system into another, and the destination system is object oriented.  So I want to represent each object in its own coordinate system, that of its bounding box, with the objects then translated and rotated appropriately, this being the representation used in the destination system.
Hello, I've raytraced and rendered and the only difference I've found  is that raytracing takes a hell of a lot longer. Am I missing something?
As I understand it, THe difference between 3D Studio 2.00 and 2.01 is mainly in the IPAS interface, along with a few small bug fixes. The IPAS code runs a lot faster in the newest version.

A shareware graphics program called Pman has a filter that makes a picture look like a hand drawing.  This picture could probably be converted into vector format much easier because it is all lines. (With Corel Trace, etc..)

I'm interested in simulating reverse (or negative) color video mathematically.  What is the transform?  Is it a simple reversal of the hue value in the HSV color space?  Is it a manipulation in the YUV color space?  How is it related to solarization?  If you want to see something truly wild, turn on the reverse video effect on a camcorder so equipped, and point it at the monitor.  This creates a chaotic dynamical system whose phase space is continuous along rotation, zoom, focus, etc.  Very very surprising and  lovely.  I'd like to write a simulation of this effect without analog grunge.  Thanks for any info you may have.  Please e-mail any info to me.  I'll post a summary.  Thanks,  --

Obviously the ARM is faster, but how much?  Why would it have to be much faster (it probably is) ? Assuming an ARM is about as efficient as a MIPS R3000 for integer calculations, doing a Compact-Video-like digital video codec is an easy task. For Software Motion Pictures (which is a lot like Compact Video, though it predates it), we get 48 frames/sec. at 320x240 on a DECstation 5000/200. That machine has a 25 Mhz MIPS R3000.
