Re: [Paraview] ParaView v5.3: Generating textures from scalars and lookup table

Hello everyone, Does anyone have idea how to solve generating textures problem? I continued to decompose the problem and I'm curious, is interpolation of scalars before mapping performed (when OpenGL2 is selected) by shaders (on-the-fly, during display) or is an intermediate texture generated?

Re: [Paraview] ParaView v5.3: Generating textures from scalars and lookup table

David, Thank you very much for your response! I tried what you suggested and it worked, but, I'm getting bad texture, i.e. I get texture 2xN, where N is number of segments in colormap and the exported texture mapped object looks like I turned OFF InterpolateScalarsBeforeMapping flag. I would like

Hi Nenand, You might try vtkMapper::GetColorMapColors/ColorCoordinates/ColorTextureMap. I'm using this in the OSPRay renderer for example. Out of curiosity is this for the p2f3d exporter plugin? cheers David E DeMarle Kitware, Inc. R Engineer 21 Corporate Drive Clifton Park, NY 12065-8662

[Paraview] ParaView v5.3: Generating textures from scalars and lookup table

Hello everyone, I've just started building my ParaView exporter plugin using ParaView v5.3 with OpenGL2 selected for backend rendering (PARAVIEW_RENDERING_BACKEND), however, I'm having troubles with generating textures from scalars used for coloring the meshes. What I'm actually doing here is
