Research direction
This is a design decision, not a ready patch: the issue lists three options and asks for mock-ups first. Start by reading #1015 for how the principal-stress arrows and their labels are drawn, then reproduce on the qe-tension test cell (4-atom fcc, CPK spheres) with the Show in viewer option. Done means a maintainer has picked one option and a mock-up or change shows labels readable with atoms not hiding the arrows.
Written by the indexing model from the issue text.
Description
The principal-stress arrows (#1015) are drawn through the cell centre and pass through the atoms of a filled cell; their labels ("+0.484 GPa (+4.840 kbar)") are drawn at the arrow tips and collide with atoms, and the label of the axis pointing at the viewer is unreadable. Seen on the qe-tension test cell (4-atom fcc, hydrostatic tension), CPK spheres.
Options to decide (mock-ups first):
- draw the arrows on top of the atoms (no depth test, or a transparent overlay layer), or offset them outside the cell;
- one label per axis outside the cell, or the values only in the panel table with the arrows unlabelled;
- show arrows only when Show in viewer is ticked and dim the atoms meanwhile.
