shader-programming-glsl

A comprehensive guide to writing GPU shaders using GLSL (OpenGL Shading Language). Learn syntax, uniforms, varying variables, and key mathematical concepts like swizzling and vector operations for visual effects.

Access vector components freely: vec4 color = vec4(1.0, 0.5, 0.0, 1.0);

Problem: Shader compiles but screen is black. Solution: Check if glPosition.w is correct (usually 1.0). Check if uniforms are actually being set from the host application. Verify UV coordinates are within [0, 1].
