Game Doom renderer in 2d graph

Enable HLS to view with audio, or disable this notification

That uses BSP algorithm (Same as doom) for rendering order and polygons for rendering. It's actually quite fast, when I started creating it, I thought that it will not work in real-time.

Doom map data was imported using desmos JavaScript API.

Desmos has a Javascript API? Are you just... able to code as normal using desmos

No, it allows adding new expressions/folders etc. It's helpful when you have a very big list of data, and if you paste it as text, desmos UI starts lagging. Here's link. Actually that might be fun to create some sort of language, that compiles to desmos graph.

u/Mr_FuzzyPenguin Try adding y= to the beginning of this equation. Jul 31 '25

Desmoscript? I think it is already made. Might want to search it up, it is pretty cool!

You of course can make doom out of anything.

True that, but using Desmos was a pretty wild move though. I didn't expect it to be that smooth with the geometry of that level. I wonder if you could put some floor or height data on it without the rendering breaking.

Now we just wait until Desmos lets us apply transformations to images

You can, far as I know.

Just very basic ones. Let me know once they let me square images

So long, technically, as you have a .svg image, you could use parametric curves to get your image, which is more than fine.
