generate isosurface from 3D image data (volume)
vtkFlyingEdges3D is a reference implementation of the 3D version of the flying edges algorithm. It is designed to be highly scalable (i.e., parallelizable) for large data. It implements certain performance optimizations including computational trimming to rapidly eliminate processing of data regions, packed bit representation of case table values, single edge intersection, elimination of point merging, and elimination of any reallocs (due to dynamic data insertion). Note that computational trimming is a method to reduce total computational cost in which partial computational results can be used to eliminate future computations.
This is a four-pass algorithm. The first pass processes all x-edges and builds x-edge case values (which, when the four x-edges defining a voxel are combined, are equivalent to vertex-based case table except edge-based approaches are separable in support of parallel computing). Next x-voxel rows are processed to gather information from yz-edges (basically to count the number of y-z edge intersections and triangles generated). In the third pass a prefix sum is used to count and allocate memory for the output primitives. Finally in the fourth pass output primitives are generated into pre-allocated arrays. This implementation uses voxel cell axes (a x-y-z triad located at the voxel origin) to ensure that each edge is intersected at most one time. Note that this implementation also reuses the VTK Marching Cubes case table, although the vertex-based MC table is transformed into an edge-based table on object instantiation.
See the paper "Flying Edges: A High-Performance Scalable Isocontouring
Algorithm" by Schroeder, Maynard, Geveci. Proc. of LDAV 2015. Chicago, IL.
- Warning
- This filter is specialized to 3D volumes. This implementation can produce degenerate triangles (i.e., zero-area triangles).
