| Summary | 0000875: vtkDelaunay3D - inserting points skips points | ||||||||
| Description | The function vtkDelaunay3D performs a walk from an initial tet to the tet containing the point to be inserted. This is done by a clever way, but a depth check prevents some points from being set if the walk isn't successful. This leads to triangulation where the surface isn't correct because points in between are missing, but I need surfaces on two meshes that fit if I put the same points in. I tried a brute force method, searching simply all tets when the depth test failed, it worked so far but I'm not sure if I will get a correct result in all cases. | ||||||||

My humble attempt at a correction doesn't work out and produces segmentation faults. |

Can you please send us a dataset + demo code to reproduce the bug. |

I uploaded a bugdemo.tgz. It contains: pointcloud.vtk : Point data in vtk format created by my code as an input delaunaybug.C : short code that renders the points and writes them to... testgrid.vtk compile: to compile the .C program demo.pvs: Paraview trace to view the bug. You can see points missing in the relatively regular grid. codesnippet.txt : What I tried to control the bug. Works much better now but not correct I think and presume. Replaces some lines in vtkDelaunay3D.cxx |
