Missing faces in some objects of large models. #87

Closed ebknudsen closed 6 months ago

ebknudsen commented 6 months ago

At times, as is the case for the MSBR-model, we find that some faces may be missing from some objects, causing the model to be leaky.

This seems (at least in cases) to be caused by hash code collisions in the surface hash-table

this was fixed by #88 - closing

ebknudsen commented 6 months ago

the hash-code-collisions were caused by the fact that the position of the object was not contributing to the hash-code meaning that for large models it would be likely to have collisions
