You need to perform this transformation for each of the offsets. Since the two triangles each share two points, you need to perform only four transformations. This is what the CreateBBVertices method looks like: private void CreateBBVertices() { billboardVertices = new VertexPositionTexture[billboardList.Count * 6]; int i = 0; foreach (Vector4 currentV4 in billboardList) { Vector3 center = new Vector3(currentV4.X, currentV4.Y, currentV4.Z); float scaling = currentV4.W; Matrix bbMatrix = Matrix.CreateBillboard(center, quatCam.Position, quatCam.UpVector, quatCam.Forward); //first triangle Vector3 posDL = new Vector3(-0.5f, -0.5f, 0); Vector3 billboardedPosDL = Vector3.Transform(posDL * scaling, bbMatrix); billboardVertices[i++] = new VertexPositionTexture(billboardedPosDL, new Vector2(1, 1)); Vector3 posUR = new Vector3(0.5f, 0.5f, 0); Vector3 billboardedPosUR = Vector3.Transform(posUR * scaling, bbMatrix); billboardVertices[i++] = new VertexPositionTexture(billboardedPosUR, new Vector2(0, 0)); Vector3 posUL = new Vector3(-0.5f, 0.5f, 0); Vector3 billboardedPosUL = Vector3.Transform(posUL * scaling, bbMatrix); billboardVertices[i++] = new VertexPositionTexture(billboardedPosUL, new Vector2(1, 0)); //second triangle: 2 of 3 corner points already calculated! billboardVertices[i++] = new VertexPositionTexture(billboardedPosDL, new Vector2(1, 1)); Vector3 posDR = new Vector3(0.5f, -0.5f, 0); Vector3 billboardedPosDR = Vector3.Transform(posDR * scaling, bbMatrix); billboardVertices[i++] = new VertexPositionTexture(billboardedPosDR, new Vector2(0, 1)); billboardVertices[i++] = new VertexPositionTexture(billboardedPosUR, new Vector2(0, 0)); } }

An interface is some kind of contract that you make your class (in this case, your GameComponent) sign. An interface contains a list of functionality (methods, actually) that the class should minimally support. When your class is subscribed to an interface, it promises it implements the methods listed in the definition of the interface. This is how you define an ICameraInterface interface: interface ICameraInterface { Vector3 Position { get;} Vector3 Forward { get;} Vector3 UpVector { get;} Matrix ViewMatrix { get;} Matrix ProjectionMatrix { get;} } Any class wanting to subscribe to ICameraInterface should implement these five getter methods. Whether it is a first-person or quaternion camera, if it is subscribed to the interface, then your main program is sure it can access these five fields. For the rest of your code, it isn t of any importance to know whether the current camera is a first-person or quaternion camera. The only thing that matters is that the camera can produce valid View and Projection matrices and maybe some other directional vectors. So, it suffices for your main Game class to have a camera that subscribes to ICameraInterface.
