Making WebGL Dance
summary
Explains how graphics hardware actually works rather than API trivia: samples define pixels, z‑buffer stores per‑pixel depth, GPUs run GLSL vertex and fragment programs to do skeletal animation on the GPU and per‑pixel lighting, and matrices (including a 4D projection) collapse many transforms into one. Demos include a Doom cyber‑demon with normal mapping and a brick floor using parallax mapping that fools the eye until the camera uniform is deliberately frozen.
