I don't think it's exposed in the API, but I could be wrong. I hard-coded the value here which should apply to both PySide and PyQt backends: https://github.com/vispy/vispy/blob/512a1ce22daccabc1a80356b33ab2d57cad86b22/vispy/app/backends/_qt.py#L300

@astrofrog can you post your whole env (`print(vispy.sys_info()`)? I can't reproduce this with Python 3.11.4 + PyQt 6.6 on an M1 Mac.

That's great @astrofrog - maybe look for a Qt bug but otherwise can you close this issue if you're satisfied?

Thanks @djhoese for all your work, and specifically for patiently helping me get some contributions into the project. I am happy to help where I can. My second child is...

Thanks for checking this out! The gradient magnitude example was just the original inspiration because there are examples you can find online ([example](https://www.kitware.com/2d-transfer-function-support-in-gpuvolumemapper/)). It's apparently good for revealing interfaces or...

That sounds like a separate problem I'd be happy to investigate at some time :). What I meant was I want to make sure _this_ feature doesn't make it significantly...

I'd like to! I think the status was that I need to: * possibly refactor the gradient calculation into a function (shader) * set comprehensive inputs for the transfer function...

I picked this up again today and made most of the changes discussed. One concern I have is that this is pretty similar to what the "snippets" in the volume...

There's an issue with the depth-color TF here. Basically the color is set by the depth within the texture, but ignores the distance between the camera and the texture surface....

I have an idea I think is working. I first calculate the intersection of the ray with a bounding sphere of the cube/volume. This is pretty cheap, and can be...
