XPrimitive3D interface
This is the basic interface for graphic 3D primitives. They need to be able
- to provide a decomposition consisting of simpler graphic primitives
- to provide a 3D bound rectangle as a 3D range
Retrieve bound rect of primitive
This method calculates the actual bound rect of the area in
world coordinates. Note that for view-dependent primitives,
the necessary pixel adjustments are taken into account. For that reason
the ViewParameters need to be given.
3D View-specific parameter set. The defined but not mandatory
parameters include:
double Time
Defines the point in time for which the geometry is defined. This may
lead to varied results for animated objects. This value is defined in the
range [0.0 .. n[, negative values are not allowed. If not given, a value of
0.0 is implied.

Parameter aViewParameters
3D View-specific parameter set, same as in getDecomposition.
