I LITERALLY JUST WANTED TO START DOING OPENGL, Damn- Tsoding, Nice to see you again :3

You know what would be cool? Have a game where you render the Voronoi diagram and let the user try to pin point where the seed actually is, and give points by how close to the target it gets.

Physics on gpu: Opengl has buffer feedback, you can take a buffer, write to it from the shader, then feed it back into the shader (there is a particle system for webgl using this technique). Alternately, compute shader.

How about trying do Vulkan version next?

That is pretty awesome! A voronoi visualization! wow dude! Edit: not just a visualkization, rather a whole animation! damn!

I dont know how much it costs the gpu to compute the n-th root of a number, but since you dont need the actual distance but only compare which distance is greater, you should be able to leave out the n-th root and just compare the sum of the (integer) powers of dx and dy.

34:30 Arguably something like GLAD is equally simple as it just generates said header file for you (no install if using website).

Please use vectors in your GLSL code, it makes the code look cleaner compared to spamming floats (in my humble opinion), and is often easier for the compiler to optimize.

43:30 - Great metaphor for GPU programming. Sucks we don't have all the tooling of web-developers considering it's a similar process. I want a schema standard for gpu-cpu communications that I can use to generate code snippets.

@wiktorwektor123 Жыл бұрын

You should try Vulkan and see how much code does it take to render anything. Open GL is very kind graphics API in that situation, just saying. Your 100 LoC multiply by 10 and then you will have something like this in Vulkan.

1:19:27 the reason why things are slow there is you're doing 100 separate calls to glDrawArrays, you should do instanced rendering and generate the quads (or maybe triangles would be possible and be more efficient) in the vertex shader.

@@cyanmargh macroses != code. I generally don't trust them and use only as little hacks. For example I have my own eprint function that accepts the same stuff as fprintf, but also it have mandatory arguments for filename, line number and function name, all of which are passed to it with macroses like ERROR(), DEBUG() or INFO(). But those are just function calls with some string concatination magic and intended only for debugging. Static functions are the way to go I think.
