Detailed Description

The fundamental building block of all meshes in this engine.

Layout matches GLSL std430. Uses vec4 for position/normal/tangent to avoid vec3 alignment issues (vec3 has 16-byte alignment in std430).

Size: 64 bytes (was 40 bytes before tangent addition)

Date

2026-01-21 - Added tangent for normal mapping support
