WebOct 21, 2024 · So I'm a fractal enthusiast and decided to build a 2D/3D fractal generator in WebGL using raymarching, with Typescript as scripting language. I've been a C#/Typescript dev for several years but having zero experience with 3d programming, I used Michael Walczyk's blog as a starting point. Some of my code I use here is derived from his tutorial. WebApr 5, 2024 · Raymarching is a mathematical way of rendering. It is done with distance fields (distance from a point to a primitive), constant-steps (typically used with volume rendering), and root-finders (a math approach). Normally, creating a scene like this requires tools for geometry (Maya, Blender, 3DsMax), tools for textures (Photoshop, Gimp, MSPaint). ozuna citas
