Someone had already developed ray tracing demo for msx2? Are there free downloadable from some location?

There's some -slow- utility which creates spheres which I assume are ray-traced, made by Alex Wulms. Dunno where one can download it. But in general, ray tracing is slow. The time it takes to insert a disk into your msx with a script and a ray-tracer is the time it'd take on a PC to render the picture in 24bit color. You really want to ray trace on MSX?  |

Maybe he is talking about something like "Wolfsteing 3D" on MSX? It actually uses raytracing - just a few rays to check for visibility... I remember there was a 3d maze demo released some time ago... cant remember the name |

time ago i've heard of a demo that had been developed on a msx2 using vdp9938 then re adapted on the v9990. the developer said that the improved version was more smoothly (obviously) because of the v9990. I do not remember of what kind of demo was. Would be great to find the v9938 version to see how work. I also guess that not more cpu was needed, because the author said about a decrunching operation performed in real time. Anyone know about this demo?

That was ray- casting, not ray-tracing. And it was made by xl2s, called "Maze" *click* |

That is just a videoplayer, no ray tracing on msx, as far as I know.

Actually, there are at least two ray tracing apps. One I wrote myself which didn't get any further than planes and spheres. And one was a basic app from Japanese origin which was somewhat more capable and use screen12 for output. Naturally, it was dead slow |

Spheres are for atoms, atoms are for molecules, molecules are for all kinda objects.. so basically all you need are spheres! (And oodles^oodles o' memory ) |
