I have a 3D surface (vertices, about 50k plus triangles) with specific vertex colors in matlab. I want to export this surface for visualization in ParaView.
In this context I the following questions / problems: 1) Is it possible to represent data in ParaView as a collection of vertices each with an attached color? I could only find the possibility to select an index variable in 'Coloring' that points to a colormap. In principle I could generate a variable for 'Coloring' that runs from 1 to N (e.g. N=50k) and points to a custom colormap with N entries. However, this seems complicated and inefficient ... 2) I exported my surface from matlab into the VTK format to then read it with ParaView. In the documentation of the vtk format (see e.g. http://bebendorf.ins.uni-bonn.de/teaching/Praktikum_SS13/vtk_file_formats.pdf) I found the feature of 'COLOR_SCALARS' (i.e., unsigned char values directly mapped to color). This sounds like what I want. However, I tried this but 'COLOR_SCALARS' is loaded into ParaView as a vector variable and does not directly determine the color. How can I use this 'COLOR_SCALARS' information to directly determine each vertexes' color? I would be grateful for any advice in this matter!
