Metal Lab From Scratch Metal 4
A beginner-friendly, step-by-step tutorial to Apple's next-generation GPU programming API. Build shaders, render pipelines, and real-time graphics — one chapter at a time.
What You'll Learn
From how GPUs work to building full render pipelines — master Metal 4 graphics programming systematically.
GPU Fundamentals
Understand how GPUs work, the rendering pipeline, and why Metal gives you direct control over Apple silicon.
3D Transforms
Implement model-view-projection matrices and camera systems. Bring your scenes to life with spatial transformations.
Render Pipelines
Discover Metal 4's next-generation rendering architecture. Build command buffers, encoders, and pipeline states — master the full rendering flow from CPU to display.
Shader
Write vertex and fragment shaders in MSL (Metal Shading Language). Learn to manipulate geometry and pixels on the GPU.
Textures & Sampling
Load images, create texture objects, and apply them to 3D models with configurable sampling and filtering.
PBR Rendering
Master physically-based rendering — model realistic materials, lighting, and environment maps to create lifelike visuals.
Ray Tracing
Trace rays on the GPU with Metal 4's ray tracing API. Build acceleration structures and render reflections, shadows, and global illumination.
