Re: SDK: OGLLight

Not sure, but as far as I can remember, it uses homogenous coordinates so point (x, y, z) is represented as (xw, yw, zw, w). If you are getting a return of four scalars and want to convert to 3d cartesian , simply divide the first three values by the fourth value. Maybe I am wrong, but not completely.
