[question][rendering] Open GLES
I am trying to get VTK to compile with VTK OpenGL ES support on Ubuntu 18.04 arm64 (NanoPC-T4 single board computer).
I am having some confusion when examining classes that fail to compile. For example, vtkRenderingContextOpenGL2 uses OpenGL defines/functions. However, I don't see any CMake to disable this class when GLES is requested (is
ANDROID the keyword to trigger this, or
VTK_OPENGL_HAS_ES?). Should this class compile under GLES?
It's not an ideal notes system, but I've got comments in this thread for extra info: Slicer for arm64
Tagging @ken-martin as I suspect he/you is/are the most likely source for answers.
Kind regards, Adam
