Hi!
I am creating a terrain with many billboard trees
on it. Due to the problems of 'Multiple Transparent Objs', I decide to use
OrderedGroup, and sort the trees according to their 'Z' coordinate at run
time.
So my question is:
Is there an easy and universal way to quickly get
objects 'Z' coordinate in ViewPlatform coordinate system? Otherwise we have to
do a lot of Matrix calculation.
Thanks for any help in advance.
