How to disable picking of back faces?

[makemeunsee]

Hello,

I have noticed that geometries can be picked from their back faces.
I figured that's because the IntersectionMaterial used when picking has default render_states and back face are not culled.
So I tried to force back culling on the material used when picking, alas, it does not work.

Any clue why not, or a suggestion how to disable back faces when picking?

Thanks!

My bad, setting the appropriate culling on the render_states on the IntersectionMaterial works fine. I'll submit a PR as it feels useful to have finer control on the picking.

Thanks for the PR 🙏 Makes sense that you want to control the culling and as it doesn't make sense to control the other render states, I think just passing the cull state as input makes sense.

For the record, if you would want to make a special picking function, the pick and ray_intersect are pure functions, so it's easy to copy those and adjust them any way you want.
