Conver VB to Mesh

// Initialise the D3DXMesh object:

 

D3DXCreateMeshFVF(10, CIRCLECOMPLEXITY, D3DXMESH_MANAGED | D3DXMESH_WRITEONLY, D3DFVF_VERTEX, g_pD3DDevice, &g_pCircleMesh);

 

g_pCircleMesh->LockVertexBuffer( D3DLOCK_NOSYSLOCK, (void**)&pVertices);

memcpy(pVertices, g_vCircle, sizeof(g_vCircle));

g_pCircleMesh->UnlockVertexBuffer();

 

g_pCircleMesh->LockIndexBuffer( D3DLOCK_NOSYSLOCK, (void**)&pVertices);

memcpy(pVertices, g_iCircle, sizeof(g_iCircle));

g_pCircleMesh->UnlockIndexBuffer();

 

// Then the call to draw:

 

g_pCircleMesh->DrawSubset(0);

 

 

 

 

D3DXMESH_MANAGED - Both IB and VB in managed pool.

D3DXMESH_WRITEONLY - Only writing, never reading ( change if your'e going to read ).

D3DLOCK_NOSYSLOCK - Don't wait to lock.
