Source codes. Executables for Amiga and Windows.
https://github.com/mateusz83/msRay

--- UPDATE - 26.08.2022 ---

msDevPack v0.33 features:
- wall/floor/ceiling textures
- new, faster floor/ceiling render algorithm (based on screen projection and clipping)
- mipmaps (256x256 --> 32x32)
- baked lightmaps
- distance shading
- glowing pixels

msDevPack v0.32 features:
- wall/floor.ceiling textures
- mipmaps (256x256 --> 4x4)
- baked lightmaps
- distance shading
- glowing pixels

Hello again,
I send some time optimizing the engine and adding features.

Right now I have on V1200:
- 320x200x32 - average 50 fps, near the walls its 70-80 - generally its fast and smooth.
- 640x400x32 - average 16-18 fps (slowly but playable)

Check out demo level (this video is from WinUae)

Also check out how its working on Emu68 in INSANE resolutions

Hi,
Recently I spent some time to develop my Racycaster thinking mostly about Vampire accelerators. But the main point was to test the RTG possibilities and render something at 24 or 32 bits.

Right now, I get to this point (with 1:1 pixels)
- 320x240x32 - about 15-18 fps
- 640x480x32 - about 4-5 fps
on Vampires, the Warp 1260 at now is about 2-3x slower, but as far as I know the RTG is noy yest fully optimized

but please note that these are my coding limits not Vampire or Warp limits

VIDEO OF MY RECENT PROGRESS:

I was coding in C, I don't know assembler so I don't think I can optimize the speed any further by now.
But the engine like this should problably works on Vampire like at least 40-50 fps in 320x240x32 and maybe at least 20 in 640x480x32..
it was my first RTG and System Amiga coding attempt, I am glad of the results so far. I hope I will back soon to this project
and optimize it much better.

The textured walls itselfs with shading was very fast even in 640x480x32, but adding floors and ceiling slow donwn everything. They can't be so much optimized as walls.

I also wrote a Launcher that scans thru available display modes (in fullscreen or window) that can be filtered and formated by user.

NOTE!
I would like to share my code to encourage users and coders to use more RTG modes and higher resolutions or color depths.
I would like also to hear your opinion and maybe ideas to optimize the performance

Probably the floor/ceiling is the major problem right now..
