Shader Programming Fundamentals

Status: public · Confidence: medium (0.865) · Basis: verified_sources

## TL;DR

Shader programming uses GPU-executed shader languages to control rendering and compute stages in graphics pipelines.

## Core Explanation

Shader programming defines small programs that run on graphics hardware. GLSL, HLSL, and WGSL document related but platform-specific ways to describe stages such as vertex, fragment, compute, and WebGPU shaders.
