Description

VertexData-Class. Part of the Mesh implementation containing all vertex specific data of a mesh:

• VertexDescription : Data format of the vertices.

• The local storage for the vertex data (If the data is uploaded to the graphics card, the local copy may be freed.)

• The vertex buffer id, if the data has been uploaded to graphics memory.

• A bounding box enclosing all vertices.
