I think I already fixed the text actor by running OSPRay pass for 3D objects only and have another OpenGL pass for the overlay. Regarding the grid, it might be...

I experienced it again. Should we disable OSPRay tests for macos until it's fixed?

It can be addressed of course, but it will take time

It requires a rework of the VTK polydata mapper to sample the HDRI (aka IBL) based on some magic tricks. With PBR, we use the computed specular term to sample...

Let's communicate on the PR, I'll help you there. You can just use the C code for now if you're more familiar with it and we'll move that to C++...

Here's my opinion on this topic: - Functions of the form `instance.function(arg1, arg2)` should look like `function(instance, arg1, arg2)` - Return references should become argument pointers - Returned `std::vector` should...

FYI @snoyer The suggested solution looks good to me, wdyt?

Seems to work fine here Macos arm (VTK 9.3 and VTK master give the same result):  Linux: 

Interesting! Thank you for sharing. I see nothing wrong in your code. I'll try to reproduce locally to take a closer look and let you know.

By default it seems like it's using GLES and I have a blank window. When adding `self.gl_area.set_allowed_apis(Gdk.GLAPI.GL)`, GTK seems to complain it cannot create a GL context, any idea?
