GL Mesh fir Compatibility Profile

GPU‐resident mesh: owns VAO/VBO/EBO/CBO/NBO for an indexed triangle mesh. It does not know anything about shaders or matrices.

classmethod from_mesh_data(mesh: MeshData) → LegacyGLMesh[source]

Construct a GLMesh from a MeshData container.

Parameters:: mesh (MeshData) – Must have .vertices (Nx3), .ebo (Mx1), optional .cbo (Nx3), .nbo (Nx3), uvs (Nx2)
Returns:: Ready-to-upload mesh (GPU buffers are allocated only when upload() is called).
Return type:: LegacyGLMesh

upload() → None[source]: Allocate & fill GPU buffers.
