This is much more work to implement than anyone will reasonably commit to because selection volumes can be ellipsoids, boxes, and cylinders in addition to spheres, which are all plane-intersection-unfriendly. Taking the selvol's bounding radius into account for each plane test is about the best you can hope for here, but that obviously also has edge cases to consider.

I see.
What about a simple bounding box collision?

With the current box selection implementation you can get some results that are a bit off from a UX point of view. You can have 1/3 of the unit covered visually, but because it doesn't pass the mid point it won't get selected.

I was only suggesting selection volumes because it seemed the more generic solution, but of course if the collision tests are not already implemented it's a lot of work.

A compromise like a bounding box collision would be great

You can add OOBB-based selection handling, but I would start simple and just test more sample points first.
