How to modify BVH of the SelectionManager into an OCCT Viewer

Hello,

I would like to know if it's possible to modify the BVH structure of a SelectionManager or even replace it with my own optimisation structure. I am currently working on some large AIS_Wire ?

I also would like to know if there is an optimisation structure only for the visualization (i guess not with rasterization?) ?

Thanks in advance,

Nathan,
