Detailed Description

Minimal Wavefront OBJ loader collecting vertices, triangle indices, and normals.

Parses a subset of the Wavefront OBJ format sufficient for simple triangle meshes. The constructor reads the file, extracts vertex positions ("v"), vertex normals ("vn"; optional), and triangular faces ("f"). Indices are stored zero-based. If normals are not provided, they are computed as area-weighted vertex normals from face geometry.

Faces are expected to be triangles; non-triangular faces are ignored.
Only position and normal records are recognized; texture coordinates are ignored.
When normalize is true, positions are recentered to the AABB center and uniformly scaled to fit into the unit cube (longest AABB side maps to 1).
