Detailed Description

extrude polygonal data trimmed by a second input surface

vtkTrimmedExtrusionFilter is a modeling filter. It takes polygonal data as input and generates polygonal data on output. The input dataset is swept along a specified direction forming a "skirt" from the boundary edges 2D primitives (i.e., edges used by only one polygon); and/or from vertices and lines. The extent of the sweeping is limited by a second input: defined where the sweep intersects a user-specified surface.

Capping of the extrusion can be enabled. In this case the input, generating primitive is copied inplace as well as to the end of the extrusion skirt. (See warnings below on what happens if the intersecting sweep does not intersect, or partially intersects the trim surface.)

Note that this filter operates in two fundamentally different modes based on the extrusion strategy. If the strategy is BOUNDARY_EDGES, then only the boundary edges of the input's 2D primitives are extruded (verts and lines are extruded to generate lines and quads). However, if the extrusions strategy is ALL_EDGES, then every edge of the 2D primitives is used to sweep out a quadrilateral polygon (again verts and lines are swept to produce lines and quads).

Warning
The extrusion direction is assumed to define an infinite line. The intersection with the trim surface is along a ray from the - to + direction, however only the first intersection is taken.
Some polygonal objects have no free edges (e.g., sphere). When swept, this will result in two separate surfaces if capping is on and BOUNDARY_EDGES enabled, or no surface if capping is off and BOUNDARY_EDGES is enabled.
If all the extrusion lines emanating from an extruding primitive do not intersect the trim surface, then no output for that primitive will be generated. In extreme cases, it it possible that no output whatsoever will be generated by the filter.
This class has been threaded with vtkSMPTools. Using TBB or other non-sequential type (set in the CMake variable VTK_SMP_IMPLEMENTATION_TYPE) may improve performance significantly.

Specify a strategy for extrusion.

If the strategy is set to "BOUNDARY_EDGES" then the boundary edges of the input polygons and triangle strips are swept. (A boundary edge is an edge used by only one 2D primitive, e.g., polygon or triangle.) Alternatively, all edges can be swept. (This is particularly useful when only sinple disconnected polygons exist in the input and so boundary calculation can be avoided.) By default boundary edges are extruded.

virtual void vtkTrimmedExtrusionFilter::SetCappingStrategy ( int  )
virtual

Specify a strategy for capping.

By default the points of the cap polygons are located where the extrusion intersects the capping surface. However, to preserve planarity, or to place the capping surface at the average/minimum/maximum distance of extrusion, different strategies can be used. By default the average distance is used.

Note if none of the extrusion rays intersect the trim surface, then capping is not performed, nor is an extrusion skirt sent to the output. Also note that if the capping strategy is set to INTERSECTION, and one of the extrusion rays of the generating primitive does not intersect the trim surface, then no output will be generated for that primitive. However if any other capping strategy is used, capping will succeed if at least one extrusion ray strikes the trim surface (although missed extrusion ray intersections will not factor into the determination of final cap location).

Finally, note that any capping strategy other than INTERSECTION may produce more points than expected because the output primitives may have to be "split apart" to satisy the capping constraint.
