Hardware for retro 3d stuff

Post by zolbatar » Tue Aug 20, 2019 1:16 pm

I'm playing around with some 3D stuff, and had some pretty nice gouraud shaded 3D stuff going on RISC OS on my Pi. It looks great and performs excellently using VFP instructions but it's hardly retro! I want get something similar going on an older machine...

I have my Master with Pi co-pro which could be fun, but graphical limitations hurt and it's not really "standard".

I have an A1200 as well, which I've never really done much on but I know it's a bit slower than the Archimedes machines of the time when it comes to pure CPU grunt.

Or I could attempt to get my A4000 running again and play on that.

I guess I'm looking for inspiration really.

RPi B+ & 3B+ both running RISC OS.
Poorly A4000 (battery damage, partially repaired).

Amiga has bitplanes so you may well spend most of your time worrying about chunky to planar conversions. Cpu wise an a1200 with fast ram should be similar speed to an arm2.

The a4000 will be faster, but you're stuck with a crap palette in 256 colour modes - not very good for gouraud shading! If you want better you'll need riscpc/a7000 hardware, or to stick to 16 colour modes and monochrome lighting (as I did in Horizon).

Planar graphics are painful! Reminds me of programming EGA back in the day!

16 colour us definitely no fun for shading and the VIDC palette isn't great.

I want to stick in the Acorn world I think. I have been thinking of investing in a RiscPC but feel the Pi is similar enough in some ways.
