Simulating water over terrain

If you don't want a long an boring introduction, skip directly to the virtual pipes method description . I will get a little bit sad if you do this, though x)

Particle Life simulation in browser using WebGPU

If you don't care about the explanation and want a direct link to the simulation, here you go .

Implementing a tiny CPU rasterizer (2024)

In the OpenGL course I'm teaching at a university, my students learn that the GPU uses something called rasterization to draw stuff on the screen. Then, I explain how — in theory — rasterization works, e.g. how would one write the code to draw a fixed triangle on screen. Of course, the GPU does that for us, but it is…

Implementing a Tiny CPU Rasterizer

This is a tutorial series on implementing a basic CPU rasterization engine in C++ from scratch. No GPU involved, just drawing pixels with our bare hands, emulating what the GPU usually does for us.
