[Gmsh] Finding coordinates of transformed point in python api

My apologies if this is a dumb question, but I am having difficulty working out how to find the coordinates of a transformed point in the python api.

I have created a point with:

apex_pt = gmsh.model.occ.addPoint(a_epi,0.0,0.0,0,-1)

and transform it (translate and rotate) with a routine that I wrote:


Having inspected the geometry and mesh, I know that the transformation puts the point in the correct position. However, I cannot work out how to find the coordinates of the new point. I have tried using getEntities (for dimension 0 entities) and getNodes for each entity returned, but this does not work for the one particular entity which is my apex_pt.

Any help would be much appreciated.
