rasterizer_engine

software rasterizer — 3D points to lit pixels, no GPU.

readme

A rasterizer that takes 3D points, multiplies them through a 4x4 perspective matrix to flatten them onto a 2D screen, then fills in the pixels between them. The whole pipeline a GPU normally hides — projection, triangle filling — done explicitly in software.

signal log

• 4x4 perspective projection applied by hand to flatten 3D geometry to screen space.
• triangle filling done in software, pixel by pixel.
• [ add whether you handle depth buffering / backface culling ]
