Projection not working exactly as intented.
Date: 2023-10-17. This concludes a dump of archived photos and videos. Content should be fresh from now on.

Speaking of clearing rendered textures, turns out things aren't so simple in vulkan synchronization world.

Working on raycasting from a compute shader. Not a bad start, but I forgot to clear the rendered texture.

Working on rendering from compute shaders, this was supposed to resemble Cornell box. Altogether this is already 6k lines of code.

Visually seeing contents of the depth buffer requires adding support for input attachments. They will hopefully come in handy when rendering will be combined (raycasting + rasterization)

Say hello to textures (in incorrect colorspace and orientation). This required additional 1k lines of code.

Screenshots titled "good_proj.png" and "crosshair.png". Not sure what I meant by that, I think it's about not screwing up the coordinate system.

First steps toward creating a Vulkan engine. Not the first attempt at a Vulkan engine, and not a first attempt at designing a rendering engine in Rust. This little guy already clocks in at 3.4k lines of code.

One last step before porting it to Vulkan: add slightly different shading for walls and ceilings just to make cubes individually recognizable. Old school engines would instead color each one with a slightly random shade.

Got it. It just required one additional raycasting step.

Working on adding ceiling tracing, could not figure out how to do it. On the left you can see another nasty bug, it's a (spoiler) asymptote on a division by zero.

When I said "it's working", I lied. It actually traces only horizontal walls, here the ugliness is in full display.

Not an ideal frametime. I think I was chasing an obscure bug.

3. Profit
The proof-of-concept engine is now working. Single-threaded, unoptimized, on crappy laptop CPU, and still ~100 fps.

Working on a voxel engine. It's not working well so far.

Heightmap demo from VoxelSpace. Pretty good resource, highly recommend this one, and of course Lode's tutorial.
