Calculating the perfect bounding sphere is an expensive operation.
You need to calc the convex
Calculating the perfect bounding sphere is an expensive operation.
You need to calc the convex hull which is O(n log n).
osg uses a fast approximation which is generally good enough.

Hi All,
I'm having problem computing the global bounding sphere of my model.
I debugged OSG (2.8.0) and discovered that the bounding sphere of a geode
(BoundingSphere Geode::computeBound()) is
computed as the bounding sphere of the bounding box that includes all its
drawables !?!
Why that?
