Guess what? I lied about the RAY software working on a VAX. Well sort of.... It compiles, and runs. However, everyone who tries to download the .TMP file gets garbage. The reason? Simple, the VAX does numbers from low to high byte and the 68000 does the opposite. So all of the fwrite() calls (in FIL.C) have to be replaced with the appropriate "number flipping" routine. FYI: I have done this (as part of working on DBW_Render V2.0) and also made a version of RAY2 which runs on the VAX. These will be available as part of the major DBW_Render rewrite (hopefully in a few months). BTW: RAY2 has been changed to do a "median split" algorithm instead of a "poularity" based one which means that non-ham (32 color images) are almost indecernable from the HAM (4096 color) versions! See the 1986 SIGRAPH proceedings for details on color compression.

I've been wanting to use our VAX for the ray tracer since my Amiga is not idle long enough to provide enough time to do any images. BTW, Dave, I heard a rumor that Byte by Byte has picked up the rights to your animation stuff (used to do the juggler). Is this true? Does this mean future versions of your software is going over the counter and we'll have to negotiate with them? What's the scoop?

AmigaWorld reports that Graham's ray tracer will be available from Byte by Byte this summer. -- Marco
