Summary | 0016745: Render error in unstructured grids | ||||||||
Description | See attached data for PVSM and PVD files. This is an unstructured 2-D grid with cell-centric properties IntValue and FloatValue. Paraview 5.0.1 and 5.1.0-RC1 render incorrectly: cells are not colored solid; instead they are bisected and shown as two different colors. Paraview 4.3.1 and 4.4.0 render correctly. | ||||||||

It looks like these cells that are rendering weird have duplicate points. I checked this by extracting one of the cells that is rendering weird and then looked at the extracted points. If you create the cells without duplicate points do you get the same behavior? |

I agree with Andy. Running Extract Surface, Clean, and Append Datasets performs the following: 1) converts unstructured grid to polydata, 2) cleans polydata, 3) converts polydata to unstructured grid. I used this pipeline to generate Sample_0_cleaned.vtu. It has 30 fewer points and renders correctly. |

I dug into this and the issue is that there are triangles that have three vertices but where two of the vertices have different ids but the same exact coordinate making them degenerate (as opposed to say a two point "triangle" or a triangle with duplicate point ids) It seems that OpenGL does not increment gl_PrimitiveID for such triangles or it does so inconsistently. Checking for and eliminating these when building the IBO solves the issue but does require analyzing the points when building the IBO making that process slower. I'll push a topic with that change up and we can discuss. |

Asked Utkarsh to test and if appropriate close. I don't know enough about what it should look like to do so. |

Tested using attached dataset (Sample_0_cleaned.vtu). |
