i actually try to do some basic research. In other cad software there are some libraries which are doing the tesselation part. For example cad exchanger has the possibilty to use either Netgen or Mefisto to create the triangle mesh out of the CAD boundary representation.
Does someone know, which algorithm is used by the BRepMesh_IncrementalMesh function? I did only find this information page: https://www.opencascade.com/content/mesh-framework
Would be very happy for some more information!
