Should be global, but again not sure

Thanks,

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.

Anybody know what coordinate space is
used for the values returned by the OGLLight? (e.g.
OGLLight.GetLightPosition(), OGLLight.GetLightDirection(),
…)
The documentation doesn’t specify.
