Dear c4d fellows,
I'm building polygonal objects using c++ in cinema4d (r20).
I have a small question.
I need to create phong tag to make my polygonal surface smooth.
Do I need to ascribe phong tag to each polygon constituing the surface or a single phong tag to the whole surface?
I scanned through different sources of c4d forums and met no formal math definition of a phong angle.
Does somebody have a good source with explanation of phong angle in cinema 4D?
Also, as far as I understand I can easily set up the normal direction to orient the polygons correctly.
Here is a very self explaining example from sdk:
But I heard that phong tag might override normal tags.
It is quite scary.
Suppose I set up my normals for each polygon of my surface (with love and care). Then I introduce phong tag and ... all my normals will be destroyed?
