Module normal_map 

CPU software rasterizer for FLAME normal maps.

Produces an RGB image where each pixel encodes the interpolated surface normal at that point: RGB = (normal.xyz + 1) / 2 * 255.

Performance Optimizations

This module includes several performance optimizations:

• SIMD-accelerated vector operations using portable_simd
• Tile-based rasterization for improved cache locality
• Incremental edge evaluation to reduce computation
• Inline hints on hot path functions
• Pre-computed reciprocals to avoid divisions in inner loops

Structs

Camera

Simple pinhole camera for rendering.

NormalMapRenderer

CPU rasterizer that renders per-vertex normals of a Mesh into an image.
