I understand i need to get the Dotproduct of the 2 vectors and then set the rotationz for the bottom teapot so it looks up at the other above it ,do you have to convert the DotProduct to radians as its in degrea's?
vectors are
D3DXVECTOR3 TeaPotPos(0.0f,-3.0f,-10.0f);
D3DXVECTOR3 TeaPotPos2(0.0f,3.0f,-10.0f);
