monkey patching for conversion from and to OCC <-> Compas

jf--- commented 3 years ago

hi @brgcode cool to catch up on all things OS, BRG & Compas...

Perhaps a convenient way to continue the conversation is by PR?

hereby some thoughts wrt monkey patching pythonocc & compas for smooth interoperability rather than inheriting, I think monkey patching seems pretty convenient here...

sounds good @jf--- and indeed was nice to catch up. we should do that more often :)

to further the discussion, i guess it would be better to focus on stuff that OCC can do for compas behind the scene, rather than the explicit conversions i was experimenting with. the latter are good for understanding how things work but they are not very useful. tried something similar for a sphere as for the box but that clearly doesn't work the same way. can imagine this is like that in most cases...

some ideas

intersections with curves and surfaces
projection of points onto curves or surfaces, along specified direction or to closest point
curvature and normal/tangent at points on curves and surfaces
csg trees with only end result converted to mesh
...

would it make sense to use the control points, knots, ... from rhino to recreate geometries here and compare the results of the above operations?
