It doesn't work with Pi4, I thought you have Pi3.

Yes I have a 3A+ so it should be quicker than not slower

The POC Warp3D lib is specific to Pi3/video core IV and will not run on Pi4 models, those have video core VI.

I've quickly added Mesa support to SDL 1.2 and I'm now using it as a 16 bit triangle renderer for my old 3D engine PolyNova. It's kinda cool to revisit code that I wrote over 25 years ago, I still remember writing some of it

I needed high colour support because it uses real-time dynamic lighting which would look just plain nasty on AGA. I'll post up a demo to EAB for testing on PiStrom when I get it working properly.

i don't think this software only version of Mesa is going to be much use apart from some simple 3D drawing (due to performance). I could look at adding back hardware support but I don't know if there is much point at this stage. Maybe I'll just release what I've done and let someone else hack around with it for PiStorm.

I was considering using it to port Half-life to 68k but I think it would be very slow using software (even if I could get it running).

Guess half-life does not have a software render built in ?
For games that rely on hardware 3D acceleration we really need a proper Warp3D/GL driver, then it will fly with PiStorm.
It would open many doors for classic Amiga even with only OpenGL/MiniGL 1.x support.



Maybe team up with Paraj ?

Half-Life is just a modified Quake engine (It has been referred to as Quake 1.5) so a software renderer should be doable. In fact you can already run this very buggy conversion of Half-Life on some Amiga Quake engines:

I've been working on porting Xash3D but will prob put that on hold now.

Yep agreed but I'm not interested in low level driver development. I'll leave that to someone more talented than me.

Good to know but if I was going to release a new port then I'd want to do it properly (like my other ports).

Marlon was working on Xash3d port and got it running but there were endian issues

He mentions that there is software rendering.

Cool, that's good to hear.

Like I said though, needs hardware acceleration to be worth doing I think.
