Hello everyone,

I would like to know if it is possible to use texture image files in .ktx2 or .basisu format in C++ VTK (not VTK.js).

If it is not implemented yet, how can I approach it?

Is this something the OpenGL driver needs to support or is it a file format VTK needs to be able to read from disk?

Its more about having a image reader for this format that can produce a vtkImageData.
