GLSL, distance functions, raymarching — drawing form on the GPU.
An article listing signed distance functions for primitives such as spheres, boxes and tori, along with operations like union, subtraction, intersection and smooth blending — all with GLSL code. A reference dictionary for building solids from equations.
Under the banner "Coding Adventures", this channel implements fluid simulation, ray tracing, terrain and planet generation and more from scratch. You see how physics and algorithms turn into images step by step, which makes the techniques easy to adopt.
Articles on computer graphics, mathematics, shaders and fractals. Its explanations of signed distance functions and raymarching are standard references for anyone drawing shapes with equations.
A node-based visual programming environment developed by Derivative in Toronto. It is widely used for real-time visuals, projection and sensor-driven interactive work.
