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*

@Wolf:cannot verify... link unreachable...

hmmmmmmmm... so they took it offline. I still have it on my omnipotent harddisk .. ^^ .. Sjoerd/GhostwriterP: can it be added to our downloads?

We still have to re-upload our site.

wolf_: yes, you can add it to your download database, no problem.

There!

thx, but i'm not sure it's this, the demo i've in mind is another, try this link, where it is mentioned :
www.mccm.hetlab.tk/millennium/milc/vdp/topic_7.htm
and search FLI-PLAYER

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 )

wolf_: can you give me the proof that atoms are spheres?

sjoerd: did you already get the prize for MSXDev?
PS: your site is quite fun Please upload the rest, so that it will be even more fun
