Detailed Description

Represents a single geometric mesh imported from a model file.

The Mesh class stores all CPU-side vertex attributes and index data for one mesh, as imported from an Assimp aiMesh. It acts as an intermediate container before the data is transferred to GPU buffers (via MeshDataGpu).

Each Mesh instance is associated with:

• One parent Model
• One ModelMaterial describing surface properties
• One or more vertex attribute streams (positions, normals, tangents, etc.)

Note

This class does not handle GPU resource management.
