Hello, Its a bit complicated so i didn't know how to search about this exactly. I have a 3D Point in 3DWorld, i want to know in which side the point is based on the Camera position / Angle. With Side, i mean, Up Down and Right Left. I thought i need use D3DXDotProduct but i dont even know where to start in order to use it. Thanks for any help :)

You should project the 3d point so you have the 2d location of the point on the screen, then from there it should be really easy (ie if X > screen_width/2 etc)
