Ray-Bbox collision not working (too few collisions)

BVH depth and recommended stack depth

Fix narrowing conversion from `unsigned __int64` to `size_t`

Possible to add a method to test a bvh by bbox?

Special Case for Volume Rendering

The `[[nodiscard]]` attribute should be used more often

Serialization/deserialization uses `size_t`

Make Install Optional

aboult add remove or modify operation

Using in a gpu context ?
