Base class of 3D spatial entities (topology geometry group)
vsol_spatial_object_3d is the base class of all 3d spatial entities. It provides ref counting, timestamps, a bounding box, ...
Modifications
1995/12/xx JLM
Replaced the SpatialGroup pointer by an IUBox bounding volume.
See the discussion in SpatialGroup.h for the rationale.
The bounding volume is updated according to a timestamp
mechanism similar to that used in 3D display. That is,
if the vsol_spatial_object_3d is modified it is "touched" to
set the timestamp. Then, any request to bounding information
automatically updates the bounding volume if necessary.
1996/12/16 Peter VANROOSE made destructor protected
2000/05/03 Peter TU ported to vxl
2000/05/12 François BERTEL add cast_to_group() because VXL is not compiled
with -frtti :-(
2002/12/12 Peter Vanroose added cast_to_region()
2003/01/08 Peter Vanroose made bounding box "mutable" and changed interface
2003/01/09 Peter Vanroose deprecated set_min_x() etc. and replaced with
more safe set_bounding_box() and add_to_bounding_box().
(The old setup only worked correctly when (0,0) in bbox.)
2004/09/06 Peter Vanroose Added safe cast methods to surface_3d
2004/09/17 MingChing Chang Add cast_to_region().
2004/09/21 Ming-Ching Chang Make clear distinction between 2D and 3D.
Add some missing parts to 3D classes.
2004/09/27 Peter Vanroose added empty_bounding_box(), set_bounding_box(box)
and add_to_bounding_box(box)
2004/11/15 H.Can Aras added inheritance from vsol_spatial_object, which introduces
inheritance from vul_timestamp, ref_count and vsol_flags_id
classes. members related to id, flags and tag are moved to
newly-created vsol_flags_id class.

Allows derived class to be loaded by base-class pointer.
A loader object exists which is invoked by calls of the form "vsl_b_read(os,base_ptr)". This loads derived class objects from the disk, places them on the heap and returns a base class pointer. In order to work the loader object requires an instance of each derived class that might be found. This function gives the model class to the appropriate loader.
