Algorithm class for computing topological hierarchy of multiple poly data models. The levels of the models are determined according to the models they contain, an outer model always having larger level value than the inner ones. To determine whether a model contains another, their bounding boxes are considered. It is possible to constrain a gap or allow the inner model to protrude the surface of the outer one. The size of this gap or allowance is defined as a factor /sa ContainConstraintFactor of the outer model size. This algorithm can be used to automatically determine optimal opacities in complex scenes.

◆ ContainConstraintFactor
| double vtkTopologicalHierarchy::ContainConstraintFactor |

Constraint factor used when determining if a poly data contains another It defines a 'gap' that is needed between the outer and inner poly data. The gap is computed as this factor multiplied by the bounding box edge length at each dimension. In case of positive value, the inner poly data has to be that much smaller than the outer one In case of negative value, it is rather an allowance by which the inner polydata can reach outside the other
