Why is wrapping coordinates not making my simplex noise tile seamlessly?

I've been trying to create a fake 3D texture that repeats in shadertoy (see here, use wasd to move, arrow keys to rotate) But as you can see, it doesn't tile. I generate the noise myself, and I've isolated the noise generation in this minimal…

Cylinder drawn with triangles in OpenGL

It's drawing a cylinder with stacks and edges but the problem is that stacks are connected to one point instead of a new one. Maybe a picture will show it better: And here's how I'm rendering the side because disks are rendered separately: for…

Size issues when creating a procedural mesh generator in Unity

I've been working on building a procedural generator for Unity, that takes in noise and uses it to build a height map. So far, everything seems to work as long as I limit the size of the mesh to around 250x250. If I attempt to make a larger mesh,…

Finite State Machine for Generating Names One Letter at a Time

I recall taking a class several years ago where I was given an interesting example of a finite state machine in which each state contained a letter and had multiple paths that led to other letters that generally followed them in a word. Some of the…
