A single-header C++ software rasterizer implementing a programmable rendering pipeline (vertex and pixel shaders) with no external dependencies, written with extensive Chinese comments. It is designed as a teaching tool that lets beginners learn 3D rendering internals by reading and modifying a small (~200-line core) D3D-style pipeline.

Use cases

• learn how a software rendering pipeline works
• implement vertex and pixel shaders in C++ for study
• understand rasterization with edge equations and barycentric interpolation
• see how perspective-correct texture mapping is computed
• render 3D models with lighting to a bitmap image
• study a minimal alternative to Direct3D/OpenGL internals
• teach computer graphics fundamentals with runnable examples

When to choose

• you are learning or teaching 3D rendering fundamentals from scratch
• you want a tiny, dependency-free, readable software rasterizer to experiment with
• you prefer debugging shaders as plain C++ code with breakpoints
• you need a D3D-like pipeline API in a single header for educational projects

When to avoid

• you need high-performance GPU-accelerated rendering in production
• you are building a real game or application rather than learning
• you need a full-featured rendering engine with scene graphs, materials, or asset pipelines
• you require official English documentation
