[Paraview] ParaviewWeb: True color volume rendering

[Rajvikram Singh]

Hi Sebastien
    Thanks to all the help from you guys we made good progress regarding rendering multi-channel volumes. The users have come back with another request that I've been unsuccessful in resolving.

The original volumes are a stack of RGB images and the users are familiar with seeing them as images. During volume rendering since the lookuptable changes the colors, they are confused by the features and want to render the true color of the voxels. I've been toying with generating a LUT that could map the 16-bit 3-channel RGB color to a linear table and basically the table was so big that my standalone Paraview failed to load it up successfully.

I was wondering if there was any easy way to use access the texture based volume mappers provided by VTK ? I can write code using a vtkVolumeTextureMapper3D class to render the volume with correct colors. If I could access the mapper through ParaviewWeb, I could render true colors.

Any thoughts ?

Thanks
Raj
