[Bf-funboard] Use of bounding box to implement sun shadow mapping in GE.

[pavel siska]

Hi,
I don't know if this is already in development, but my idea was to use
bounding boxes to calculate shadow maps similiar to lamp shadow mapping
implemented in apricot branch but they would be orthographic(or direct).
(1) Every object in a scene would have its own shadow only in resolution of
its bounding box.
(2) Objects with bounding box behind other bigger object would be ignored by
this sun light.
(3) ShadowBuffer size could be set up by global number value or specific
objects could have its own shadow buffer size (like trees..). This can be
handled by groups.
(4) Object far from camera would have a reduced shadow buffer size....


So what do you think? :) Is it a good idea?
