Triangular Color Wheel in C

A live coding session building a triangular HSV color picker widget in C for a software-rendered game engine. The developer implements the color wheel from scratch using barycentric coordinates to interpolate saturation and value within a triangle, while the outer ring represents hue. Key topics include HSV-to-RGB conversion (borrowed from raylib), software rasterization of triangles, polar coordinate math for placing triangle vertices, and immediate-mode UI component design. The session also touches on the game's entity system, level editor, and the developer's philosophy on copying single functions from libraries instead of taking full dependencies.
