Let's say I have something like this:
struct MyVertex
    float x, y, z;
    D3DXCOLOR diffuse;
    float u, v;

// Init D3D and all that jazz

nVerts       = 1000;
MyVertex*  pMyModel;
pMyModel   = new MyVertex[ nVerts ];

// Assign something to pMyModel

Can I then create my vertex buffer by saying something like this: pD3DDevice->CreateVertexBuffer( sizeof(pMyModel), ... ); All of the books, tutorials, etc seem to define the size of the buffer more like this: pD3DDevice->CreateVertexBuffer( sizeof(MyVertex) * nVerts, ... ); Is that just to spell out what you need to give it, or is there some potential difference in the two? -John [edited by - Teknofreek on August 18, 2002 4:16:18 PM]

sizeof(pMyModel) will return 4, so your vertex buffer will be a total of 4 bytes long. you need to do it the other way.
