mini3d

The 3D software rendering tutorial, without any performance optimization, mainly shows people how to write a software renderer with a fixed pipeline. Although the main body code is only 700 lines, the sparrow is small and complete. The source code has only one mini3d.c, and a single file implements everything and is easy to read. No third-party library dependencies, no complicated project directories. Standard D3D coordinate model, left-handed system plus WORLD / VIEW / PROJECTION three matrices. Implementing Cropping: Simple CVV Cropping. Up to 1024 x 1024 textures. Use the depth buffer to judge the image before and after. Perspective Texture Mapping and Perspective Color Fill. Accurate polygon edge coverage calculation. The rendering engine has only 700 lines, the modules are clear, and the backbone is prominent. Detailed comments, detailed comments on the main code.
