[Bf-committers] Material Nodes: No normals in worldspace?

[Tobias Oelgarte]

This sounds really good. As impatient as users always are, I like to see 
it inside blender as soon a possible. ;-)

The minimum I would need is the normal of the material (in world space 
or/and local object space), together with the world space vector of the 
view. Do you have some hints on how you thought it to be implemented 
(how to access the data) after your discussion?

Greetings
Tobias
