Description

Originally reported by: John ZuHone (Bitbucket: jzuhone, GitHub: jzuhone)

A number of callbacks do not work properly with non-cartesian datasets:

  • Anything that does vectors, i.e. QuiverCallback, VelocityCallback, MagFieldCallback, etc.
  • Drawing grid or cell lines, i.e. GridBoundaryCallback, CellEdgesCallback
  • Contouring

This will take a substantial, focused effort on the part of one or more people to get working properly.

I'm marking this 3.3 but I'm not sure if that's what we want or not. Open to having it pushed back.

Contributor guide

Research direction
Investigate the callback implementation for non cartesian datasets. Identify where Cartesian assumptions are made and design a generalized approach using coordinate system abstractions.
