Hi,

I am looking for the bests 3D games/demo on MSX, the ones that really pushes the msx to its (low...) limits in the 3D. I wonder how many polygons can be handled on a turboR versus MSX2.

I remember playing elite on MSX1 tape and also a msx2 demo with a cube with each face filled.
Other inputs ??

North Sea Helicopter
Cosmic Shock absorber
Return of Jelda

For polygon-based 3D, the VDP is not on your side..

Elite?

Doom style raycasting?

Elite is an old but but very entertaining game , in the space you have to buy/sell/trade/fight,
accomplishin miison : very intersting and there was some 3D with lines.

Well VDP accounts for polygon filling only not 3D calculation , optimzation could be to calculate 3D tranformation while VDP is busy drawing a line of the polygon...

thanks for the note , all these games are msx1 with no polygons , only lines, and slow ...
are the msx limitss reached with these titles ?

In Elite only sun has filled graphics IIRC...

Some good candidates definately worth to check out:

MSX1: Red Zone
MSX2: http://www.msx.org/Realtime-texturemapped-3D-for-MSX2.newspost2773.html
MSX tR: F-Nano2

Bosconian 3D by Microtech, for MSX Turbo R

@ Leo: Return to Jelda is for MSX2 or higher, but indeed slow and only lines nonetheless.

I think this is quite doable. There was a nice raycasting demo for MSX2 by xl2s guys, afair... anyway, raycasting is a nice thing to try, actually I am doing some tries with a raycasting design, but just some early concepts, not a line of code *yet*.

The problem was that it was just a demo, not a game.

thanks i guess the realtime texture mapped 3D for MSX2 is the one that shows the best what i wanted to see : it shows quite a lot of difference between turboR and MSX2 .
For me that means that the CPU calculation speed makes a lot of difference and VDP is not the bottleneck. I guess all the job is done in RAM and then there just a transfer to VRAM which does not account for a large part of the time otherwise turboR would be as slow as msx2

But the walls and (masked) sprites worked pretty fine, I doubt that adding all game-logic could be a big problem, once the engine is done.
