Proper 3D isn't trig, it's linear algebra. My raycasting also is a proper 3D projection, but it's a shortcut that just requires some basic math. You could make a Minecraft-style renderer in Graal that would probably run at 20 FPS without textures using some neat tricks that I picked up over the years as a graphics programmer on really low-end devices. But again, textures would be difficult because of the way Graal inefficiently renders stuff.

But rendering could be a problem, Graal starts lagging when you try to render anything above about 1,000 polygons.
Do you know any good sites that are informative?
I know my way around sine and cosine, but tan not too much.
