## Background
|
|
|
|
From `edu/TODO.md`: Hands-on: Shader programming.
|
|
|
|
A practical introduction to GPU shaders, written with Rust as the host language. The course covers the graphics pipeline conceptually and has hands-on exercises writing WGSL shaders driven by `wgpu`.
|
|
|
|
## Content outline (suggested)
|
|
|
|
### Part 1 — The GPU and the Graphics Pipeline
|
|
1. CPU vs GPU: parallel execution model
|
|
2. The programmable pipeline: vertex shaders, fragment shaders, compute shaders
|
|
3. What is WGSL? (WebGPU Shading Language) — syntax overview
|
|
|
|
### Part 2 — Setting Up with wgpu
|
|
4. What is `wgpu`? Cross-platform graphics API in Rust
|
|
5. Exercise 1: Create a window and clear it to a colour (the GPU 'hello world')
|
|
6. The render loop: swap chains, frames, command encoders
|
|
|
|
### Part 3 — Vertex and Fragment Shaders
|
|
7. Vertices, buffers, and the vertex shader
|
|
8. Interpolation and the fragment shader
|
|
9. Exercise 2: Draw a coloured triangle
|
|
10. Exercise 3: Animate the triangle using a time uniform
|
|
|
|
### Part 4 — Textures and Samplers
|
|
11. Texture coordinates (UVs), texture creation, sampler config
|
|
12. Exercise 4: Render a textured quad
|
|
|
|
### Part 5 — Compute Shaders
|
|
13. Compute pipelines: dispatching work groups
|
|
14. Storage buffers and read/write access from WGSL
|
|
15. Exercise 5: GPU-accelerate a particle simulation
|
|
|
|
### Part 6 — Going Further
|
|
16. Post-processing effects (bloom, blur) — conceptual overview
|
|
17. Signed Distance Fields for font rendering
|
|
18. Resources: Learn WGPU tutorial, Shadertoy, The Book of Shaders
|
|
