Direction in cyclic spaces

Related to the edition of rotation via 2d gradients, i stumble upon a nice little logical issue: how to pick the shortest path form current value to target one when space is cyclic and not linear. Indeed, rotations are cyclic, PI and PI*3 are not the same angles, ok, but you end up at the

UI for rotation editing #2

First prototype of a widget to edit 3d rotation via a 2d plane. The 3 buttons below the gradient allows plane selection ( XY, YZ or ZX ).The black area in the Y axis is a constrain ( between 90° and 270° ). Still a lot of stuff to be done, like the processing of

UI for rotation editing #1

I wanted to enable rotation editing via a simplified 2D UI for futari-app. I have started by the most obvious way: 3 concentric circles (XYZ axis). Even if the design was cool and super simple, there was a huge problem with this widget: NOTHING is circular in the UI! Obviously this appeared once the graphical
