Module glyph_3d_renderer 

Instanced 3D glyph rendering with PBR G-buffer output.

Groups glyphs by character, issues one instanced draw call per unique character. Outputs to a G-buffer: albedo, normal, metallic+roughness, emission. The existing deferred pipeline resolves lighting including SVOGI.

Structs

Glyph3DBatch

A batch of instances sharing the same character mesh.

Glyph3DInstance

Per-instance data for 3D glyph rendering. 80 bytes, GPU-friendly.

Glyph3DRenderer

Glyph3DVaoLayout

Describes how to set up the vertex attribute layout for 3D glyph rendering. This is a reference for the OpenGL setup code, not executable.

Render3DConfig
