| Summary | 0014350: "Color Map Editor" -> "Enable opacity ..." extremely slow and throws errors | ||||||||
| Description | Bug report is for Paraview 4.0.1-394-g0bf0d74 64bit, git-pull on 2013-10-13 When extracting a slice from an unstructured dataset, coloring it with a variable, opening "Color Map Editor" and checking "Enable opacity ..." get extremely slow and throws gazillions of errors: ERROR: In /tmp/ParaView/VTK/Common/Core/vtkDataArray.cxx, line 469 vtkFloatArray (0x1f1809d0): The number of components do not match the number requested: 3 != 1 Bye, Carsten | ||||||||

Addon: I tried to color on the basis of the velocity field (3d-vector). If I choose a scalar, it works o.k., no errors. |

Workaround: Compute magnitude of the velocity with the calculator, use the result |

Thorenz, I tried to replicate this, and could not. Could you please provide us exact steps how to replicate this error (complete with dataset)? For instance, that works is: Linux, master, local server. Open Can.exo (from the ParaView data), all variables on, apply. Color by ACCL. Color Editor/ Enable Opacity. I tried magnitude, and X, and Y. No errors were thrown, which is very likely that is slowing you down. |

Hi Alan, here are the steps to reproduce: - unpack attached file - load OpenFOAM-dataset "result.foam" - extract slice - Select as "Coloring" cellbased U - Edit colormap - Enable opacity mapping and update Now it should throw some errors. Bye, Carsten |

I did replicate this bug. |

Another way to reproduce: + Sphere, Apply. + RandomVectors, Apply + Color by BrownianVectors + Uncheck "Interpolate Scalars Before Mapping" + Edit colormap + Enable opacity mapping and update The problem is vtkDiscretizableColorTransferFunction::MapScalars(...). It's asssuming scalars is single component as well as it's using the "slow" API to access data. |

Change-Id: I37d96061fcda8498707972ce9e243860b539bbbe VTK commits: commit 92f48c6f056be1041c00f46d8bc9fc6e336bbe69 Author: Dan Lipsa <dan.lipsa@kitware.com> Date: Mon Nov 25 10:27:50 2013 -0500 Test for generating opacity from vectors (multi-component scalars). We either select one component or compute the vector magnitude. We test vtkMapper::InterpolateScalarsBeforeMapping on or off. Change-Id: I9ed01063c6858dca99297311c509e1fea0f2099d commit caf6bf1d44104804422d7e3559dbad6e9914b536 Author: Dan Lipsa <dan.lipsa@kitware.com> Date: Fri Nov 22 14:34:11 2013 -0500 Compute opacity corectly for vectors. Compute either vector magnitude or select the correct component. Use data pointers instead of general api for accessing tuples.

This variable is not set anywhere, only tested. Additional tests are included because of this change : tcl:squadViewer, cxx:RenderNonFinite, SurfacePlusEdges, TestLabelPlacementMapper Change-Id: I1ffa1462d6fb4aed3fb0ee60ec94ffae93b48fe0 |
