Two questions:
1. In the MegaPov documentation regarding variable reflection, it states:
-- start quote --
You can make reflection_min less than reflection_max if you want, although
the result is something that doesn't occur in nature.
-- end quote --
Should that read the other way around as the docs indicate that if I'm
looking directly at a plate of glass (for example) I could have no
reflection (reflection_min 0), and if I press my face to the glass and look
at the surface I can get a mirror effect (reflection_max 1) and this would
be reflection_min < reflection_max.
Or am I just misunderstanding the whole thing?
2. Regarding IOR.
Say I am modelling glass, then I would use an IOR of 1.5 which produces the
angular change as light passes into and out of it.
If I want to use blinn highlights, then the example uses an IOR of 20 which
is exceedingly large. Is this just for the example, or do the blinn
highlights require such a high IOR in reality?
Thanks,
Lee Brown
