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. WebMay 2, 2024 · The solution is based on the following steps: 1. Render the rectangle covering the whole view area. 2. Pass this rendering via custom vertex and fragment shaders. 3. In the vertex shader pass "original" ModelViewProjection matrix matrix_original, which is intended to render rectangle on the whole view area.
