Research direction

The issue names no files, tests, or entry points. Start by checking the existing Polyscope Python documentation and the mouse-event, mesh-picking, and projection APIs; done would be documented or implemented answers for callbacks, 3D click coordinates, face indices, and closest-vertex picking.

Description

First of all thank you @nmwsharp so much for this super beautiful visualization library cpp+python!
I wanted to ask how a few things which I fail to find the documentation for and I think might be implemented already -

  • How do I attach a callback to a mouse event?
  • How do I get the projection of my click on the mesh (3D coordinates)?
  • How do I get the picking info - like the face index? closest vertex?

I'm currently trying to assign vector constraints on specific faces through UI and these will be very helpful:)

Thank you so much again!
