ability to check if point is in mesh?

hello - is there a way to check if a point is located inside of a mesh? or a workaround for the older function public boolean contains(final WB_Point3d p, final boolean isConvex)?

note: this question comes from @amnon's generative typography w/ processing example on sphere packing

    A working example works better in this case. Check MCVE for more info.

    Link to the example could be also helpful.

    sorry about that. i'll remember to check that out going forward.

    i made a new issue at github.com/wblut/HE_Mesh and wblut/frederik vanhoutte responded to/closed the issue. copying their response here:

    yes,

    HET_MeshOp.isInside(mesh, p);

    But if you want to check many points and the mesh doesn't change, this is a lot better:

    WB_AABBTree tree=new WB_AABBTree(mesh,4); HET_MeshOp.isInside(tree,p);
