[tuhopuu-devel] Minnaert shader discussion

[Jorge Bernal (lordloki)]

In the today's meeting (04/04/2005) it has had a discussion about the 
integration of Minnaert shader in the Blender “official” cvs.

The principal problems, that it was indicated to solve before its inclussion, 
are:

Several persons say that the current implementation is “not” a real 
implementation of the minnaert shader and (to avoid confusions) it dont has 
to name “Minnaert”.

Too, the “darkness” factor has to change of name because one did not 
correspond with the “darkness” factor that is into the Minnaert formule. This 
one could make confusion if, by example, somebody try to use “darkness” 
factors of tables, etc.

Moreover, it has been said by another people too that could be better commit 
the “real and the nvidia” shaders by separate.

Too, it has been said that it could be commit with a button to toggle between 
both implementations.

I think that the current “Jonanthan Merritt” implementation is the one that it 
mixed the better of the both implementation by his simplicity and usability.

IMO, i would changed the actual name of the Minnaert shader to something more 
like “velvet-satin-blender” shader to avoid confusions with Minnaert shader.

May be, it can do a document where it puts how introduce “real” darkness 
factor in order to maintain certain compability with Minnaert shader.

What do you think about this?
