Computes the 3d location of the binocular point where 0,0,0 is the viewer between the eyes and z runs out from viewer,
x horizontally from left to right in image with 0 at center, and y like x but vertically in image.
Computes the 3d velocity of the binocular point where 0,0,0 is the viewer between the eyes and z runs out from viewer,
x horizontally from left to right in image with 0 at center, and y like x but vertically in image.
If enabled=true the bias operates normally, if enabled=false,
