What You'll Master

A comprehensive journey from mathematical foundations to production-ready shader effects

Foundations

  • • The GPU Canvas
  • • The Coordinate System
  • • Color Mathematics
  • • Introduction to Functions

Core Techniques

  • • Procedural Patterns
  • • Randomness and Noise
  • • Smooth Transitions
  • • Distance Fields

Advanced Techniques

  • • Time-Based Animation
  • • Advanced Texture Effects

Appendices

  • • Appendix A: Production Techniques
  • • Appendix B: Shader Library Organization
  • • Appendix C: Accessibility Checklist
  • • Appendix D: Performance Reference

Course Philosophy

• Build on a Solid Foundation: A deep understanding enables creative freedom
• SwiftUI at the Core: Every shader is built to run with SwiftUI
• Real-Time Feedback: Every concept is demonstrated live with real output
• Step-by-Step Complexity: Concepts build naturally on top of each other

Prerequisites: Swift programming experience, basic SwiftUI knowledge, elementary algebra. No graphics programming experience required.

Why I Made This Course

I created this course while learning Metal shaders myself. When I started, shaders felt like magic — online resources either assumed a graphics background or showed cool effects without explaining the underlying logic.

With the help of Claude, I broke down every concept into something I could understand and apply. This course comes from my own journey: learning, failing, asking questions, and building up mental models for visual programming.

This isn't just a course — it's a documented learning path. I'm sharing it for free because it helped me reach new creative limits, and I hope it helps you do the same.
