The control coordinates are the corners of the quad projected
2001-09-20 05:19:47 +08:00
out onto the front face of bounding box which enclosed the impostor
geometry when it was pre-rendered into the impostor sprite's texture.
At the point of creation/or update of the impostor sprite the control
2001-12-25 05:56:22 +08:00
coords will lie on top of the corners of the quad in screen space - with a pixel error

or zero. Once the camera moves relative to the impostor sprite the

control coords will no longer lie on top of the corners of the quad in
2001-09-20 05:19:47 +08:00
screen space - a pixel error will have accumulated. This pixel error
2001-12-25 05:56:22 +08:00
can then be used to determine whether the impostor needs to be updated.
