Graph |
Gets the principal coordinate system that results of the camera facing a layer. The plane of the layer that best faced the camera is used for the calculations.
The normal of that layer is returned as z-axis, the vector that best matches the up-vector of the camera is becoming the y-axis,
and the x-axis results from the z-axis and the y-axis.
