nexcore-softrender: Pure-Rust software rasterizer

First-principles rendering from math to pixels. Zero dependencies.

Pipeline

Geometry (vertices) → Transform (matrices) → Rasterize (edge functions) → Framebuffer (pixels)

Architecture

• math — Vec2/3/4, Mat3/4, transforms, color (pure computation)
• geometry — Vertex, Triangle, Mesh, shape generators
• pipeline — Viewport, rasterizer (edge functions), fragment shading, framebuffer
