Hello OSG masters,
I have a question about BoundingBox (I checked the mailing archives
before).
You know that OSG generate BoundingBox, but it is really a box (all
faces have the same size).
I need the Bounding Parallelepiped of my scene. Not just the bigger
radius from the center applied on
HI Matthieu,
An osg::BoundingBox is an axis aligned bounding box, all faces could
be the same size as in a cube, but this is certainly not constrained
to represent cubes.
Secondly the scene graph uses BoundingBox for the Drawable leaves, and
BoundingSphere for nodes of the scene graph. This

Hi Gordon,
Unfortunately, OSG does not directly support what you want as osg'S
bounding box, is as you have seen is a axially aligned min/max LL/UR
That is not true. OSG's bounding box supports separate xmin/xmax,
ymin/ymax, zmin/zmax values, so it can represent boxes that have
different

For the case of a non-world-aligned bounding box - but still one which is
parallel-sided (i.e., a rectangular volume) - you actually do not need all
eight corners.

The osg::Bounding box only supplies 2 vec3's which effectively gives you 2 corner points and you cannot get the 8 corner
