Topology finding for patterns

compas_singular

Welcome to compas_singular, a Python library tackles topology finding of patterns, particularly singularities in structured quad meshes. Based on the PhD research of Robin Oval, this library implements data structures for quad mesh modelling, several algorithms for topological exploration and interface with Rhino3D/Grasshopper3D.

compas_singular is based on the COMPAS framework is an open-source, Python-based framework for computational research and collaboration in architecture, engineering, digital fabrication and construction.

compas_singular's Issues

rpc does not always work in all countries

Hey Robin! from features is working well in the workshop and lots of people are excited about it! Maybe one thing to consider, is to reduce the number of procedures that rely on the rpc? It is not always available or does not work in some part of the world. Maybe have a look at compas_cloud, which is a websocket-based implementation of Remote Procedure Calls. It's been working well for us so far.

a screenshot from a workshop participant in India:

literal_eval on integers

This applies to mesh_qad_pseudo.py's data method and any other methods that call literal_eval

consider changing
literal_eval(key)
to
literal_eval(key) if not isinstance(key, int) else key

There is some underlying assumption that dictionary keys of mesh elements will necessarily be strings in many of compas_singular's methods
Perhaps this is because of the way datastructures are serialised in earlier versions of COMPAS, which stringify all keys as json.dump tends to do...
However, this causes issues when the keys are already integers.

Grasshopper user object won't work.

Describe the bug

Hi, I've tried to let the compas_singular GH object to work. However lack of some package defined it couldn't run properly.

One possible issue I've noticed was:

Under
src/compas_singular/rhino/grasshopper.py

in Line 17
from compas_singular.algorithms import surface_discrete_mapping, boundary_triangulation, Skeleton, SkeletonDecomposition

surface_discrete_mapping was not defined. Also the Skeleton might be under src/compas_singular/datastructures ?

I'd really appericate your feedback.

Best regards,
Jeff.
