Alan, The PLY format is not general enough to save point or cell data. It does support point colors, and it should be possible to export colors mapped through the current lookup table with some work. However, when you load the PLY, it will not have the original variables by which you could color. It will be limited to either solid color or the colors on the surface as they appeared when the file was saved. Would you like to have the functionality of saving the colors in the PLY file? |

Yes, I would like the functionality you describe - adding the ability to save the surface color of the object - into PLY files. You are correct - this file format does not include variable arrays, only surface color at the time the file was saved. |

I think I found the PLY file format spec. It is here: http://paulbourke.net/dataformats/ply/ [^] |

Needed to create products to be ingested by slycat. |

I have another user trying to use this. Processing the output of the new CTH contour functionality. |

MR: https://gitlab.kitware.com/paraview/paraview/merge_requests/713 [^] BUG 0015997: Add ability to save color information in PLY files. The PLY writer now allows user to choose whether color information is to be saved in the output file. When enabled, ParaView uses the data sources coloring state in the active view i.e. the array to color with and the LUT to use, to pass along to the writer so that it can save RGB color values in the output dataset. |

Note that on reloading the PLY file in ParaView, ParaView will by default use a color map for coloring and hence the color will look different. Uncheck "Map Scalars" and you'll see the RGB colors saved in the PLY file which should match the color map used when saving the PLY file. |

Yes, I believe that is what the user wanted. Nice, thanks. Tested local server, master, Linux. |
