If two geometry files are loaded, and they color by same scalars name, here is a problem? #358

Closed ziqiangxu closed 4 years ago

ziqiangxu commented 4 years ago

I have loaded two geometry files, they are like this.

  1. Vessel.vtk image
  2. Segmentation.vtk image

When I show them at the same time and all color by scalars. It will like this, they are rendering by one colormap. image

It seems that they are using the same ~representation~lookupColorTable(I have read the code), is it a deliberate design？

This is by design. Internally, arrays of the same name use the same lookup table. I believe this mimics the functionality of ParaView. (@jourdain please correct me if I'm wrong by any chance.)

OK, thanks for your reply. BTW, now glance's painting has only one 3D mode, actually, the 2D mode may more useful, is it in the TODO list?

Same field name should have a shared color scale otherwise you could not compare the temperature of 2 objects accurately. If you want to get independent coloring for meshes, you should not name your field scalars everywhere. You could use the name of your geometry assuming that one is unique.

They are not using the same representation but the same LookupColorTable to allow user to compare Apple to Apple.

I see, thank you very much.
