Made the acronyms more explicit in the glossary
Sorry for taking so long to respond.
I think it might be better to remove the acronyms from the glossary. Existing definitions can be expanded to say something like:
Bounding Volume Hierarchy A hierarchical structure of geometric objects; sometimes abbreviated to :abbr:`BVH (Bounding Volume Hierarchy)`
Any links that were previously made to the acronym can be changed to the written out version. The rendered word can still be abbreviated by using the syntax: :term:BVH <Bounding Volume Hierarchy>
