WebGL Fundamentals

Teaches core WebGL concepts including shaders, buffers, textures, and the rendering pipeline for 3D graphics in the browser.

Usage

Ask about WebGL concepts, shader programming, or how to set up rendering pipelines from scratch.

Examples

• "Explain the WebGL rendering pipeline"
• "Write a vertex and fragment shader for a textured quad"
• "How do I set up a perspective projection matrix?"

Guidelines

• Always check for WebGL context creation failure gracefully
• Use WebGL2 when available for modern features like instancing
• Minimize draw calls by batching geometry
• Manage GPU memory carefully by deleting unused buffers and textures
• Use browser dev tools GPU profiler to identify bottlenecks
