hi all,
in osg there are various LocalToWorld & WorldToLocal functions.i don't
know if the "Local"and"World" have the same meaning in OpenGL,but i am
indeed confused.take the fuction
osg::Ellipsoid::computeLocalToWorldTransformFromXYZ as example, how can it
compute the localtoworld transform from just a position? does it have
default orientation? and what's the meaning of global function
computeLocalToWorld(const NodePath & nodePath)? could someone give me some
explanation? thanks very much!
