A brief intro to WebGL shaders
Source note · credited to Steve Sewell
Explains per-pixel fragment shaders through a dependency-free pointer reveal that mixes two images with uniforms and a noisy circular mask.
Source context
The summary above is grounded in the retrieved reference. The interpretation and build translation below are editorial synthesis by FORM//GRAPH.
What carries forward
WebGL need not mean a heavy 3D stack; a small fragment shader can deliver precise, performant 2D interaction.
Build translation
Reserve minimal GLSL for tactile hero reveals, image comparisons and local material reactions; preserve semantic HTML above it.
