It would help a lot if there is a toggle in the Zebra analysis’ panel to switch between the custom mesh and the rendering mesh density. The latter does not require any calculation of the mesh, which is handy when opening files with very detailed geometry. Also, this could be used to boost the framerate when the analysis is applied to detailed models, then the user could revert to the more dense mesh setting when analyzing simpler geometry. Being forced to often change the zebra mesh density from the options is too sluggish.
You can also expand the usability of that functionality by adding an option to choose from a list of user-saved mesh presets. Some of these could be automatically loaded, such like when the user makes a screenshot with “View capture to file”.
The list of custom mesh presets could be evoked by the following tools:
Zebra analysis
Curvature analysis
Draft angle analysis
Emap
View capture to file (Rhino automatically captures a user-set custom mesh density rather than the one used in the viewport)
