• Game Technologies: DirectX, XNA, XACT, etc. Sharing Vertex Buffer between meshes

  Is it possible to store multiple meshes (Microsoft.DirectX.Direct3D.Mesh) in one vertex buffer to avoid vertex buffer switching Or is it the best not to use the D3DX mesh object at all    Switching vertex buffers is really not very expensive. Even if it were, if that's your biggest performance worry, you are in a very good place indeed - there are usually a lot more important things to optimise before that. Don't worry about, and just create one VB per mesh - much easier that way. You can always change it later. ...Show All
