Hello Bald Eagle,
Thank you for your comments, this might be of interest only if I manage to model
physically realistic optical scenes. According to laws on physics, geometrical
optics in particular.
So far it does not look like it maybe because I am not using it correctly?
If I specify beamwidth of certain angle it should result in spot of light of
certain size at certain distance. If angle is changes size of the light spot
So far I do not see it in my models.
