Introduction to Shaders & WebGL

Section 1 of 5

Shaders are small programs that run directly on the GPU, enabling real-time rendering of complex visual effects. WebGL brings the power of OpenGL to the browser, letting you create stunning 3D graphics, lighting, shadows, and post-processing effects. In this course, you'll write vertex and fragment shaders from scratch and build a complete rendering pipeline.

🔑 Core Techniques

📝

GLSL Programming

Master the OpenGL Shading Language: data types, built-in functions, uniforms, attributes, and varying variables.

  • • Vector and matrix operations
  • • Texture sampling
  • • Built-in math functions
  • • Shader compilation
💡

Lighting Models

Implement realistic lighting: Phong, Blinn-Phong, and PBR (Physically Based Rendering) models.

  • • Phong reflection model
  • • Normal and bump mapping
  • • Multiple light sources
  • • PBR materials
🌑

Shadow Techniques

Create realistic shadows with shadow mapping, cascaded shadow maps, and soft shadow techniques.

  • • Shadow map generation
  • • Depth testing
  • • PCF filtering
  • • Cascaded shadows
✨

Post-Processing

Apply screen-space effects: bloom, blur, color grading, depth of field, and ambient occlusion.

  • • Framebuffer objects
  • • Gaussian blur
  • • Bloom and HDR
  • • SSAO
