Curved mappings

[Mathias Bredholt]

Hi!

I submitted a pull request to webmapper with a curved mapping expression generator. The implementation adds a "Curve" button to the expression editor, which opens a window to edit the curvature of the mapping with a slider. By pressing the "Generate" button, an expression is generated using the range of the source and destination of the mapping.

Hi Mathias – this is great! I pulled in your branch with a few modifications and merged it into master along with the python3 branch.

Hi Joe,

I submitted a new pull request with some cosmetic changes, it looks great now! Great idea with the math expression visualization.

Cheers,

Mathias

Thanks Mathias – I think this is a nice addition to the UI.

I made another change that I hope you will agree with: when the user clicks the “apply to map” button the editor now remains open, and is only closed by clicking outside the editor (we could also add an explicit “close” button if anyone finds this confusing). I think this better supports our usual exploratory workflow, in which a mapping is tweaked and then played with or monitored before being tweaked again. Leaving the editor open allows the mapping designer to see the visual representation of the curve expression while they are playing with the mapping and easily adjust it.

Cheers,

Joe

Hi Joe,

Thanks for the merge! Yes, I totally agree, it makes a lot of sense. It is probably a good idea with the close button also. I’m excited to test the mappings with an actual controller in the coming weeks!

Cheers,

Mathias
