Trackball Rotation for Bones
Steve:
Raxx: There are 4 coordinate systems that I think might be useful, World, Screen and two "Local"s:
World: defined by the global environment.
Figure Local: relative to the Figure.
Bone Local: this is defined by the X, Y, Z-axis joint rotations.
Screen: defined by the plane of the screen.
Does it make sense to support them all?
Raxx:
Hey Steve. What exactly is "Figure Local"? What kind of uses would it have that's more advantageous than the other coord systems? It seems a bit overkill to have.
"Local" to me means the coordinate system is oriented to the orientation of whatever's selected. Assuming full implementation, that'd mean if I were doing p/e/f mesh editing procedures, the axes would be oriented to the mesh shape's orientation (for example, moving in the positive Z direction is the same as moving in whatever direction its "front" is). Same for the shapes as a whole, and for objects attached to figures, and for scene editor elements when moving, rotating, and scaling. For bones it's along the joint rotations. It's what I expect would replace the old "Object Coordinates" button.
Steve:
OK, that's what I think makes sense, too.
So if you want to rotate (or move) in another plain you can rotate the view so that it's aligned with the screen and use Screen coordinates.

Found a problem in scene mode. Have attached an .an8file.
One figure with three bones and one object attached. I've put it in sequence mode and can rotate bones as normal, but when imported into scene mode, select a bone and try to rotate as per normal. Sorry to say, nothing happening.
Possibly related to slow-down posted by captaindrewi, but its not a slow down here, it just isn't moving. And if a bone is selected and you click on bone with MMB, to rotate on Z axis, the bone just becomes unselected. X and Y do not unselect, but will not move.
nb. Problem occurs on new and old figures. Tested on win7 and xp.

I confirm this happens in scene mode, perhaps its not implemented in scene mode though.
edit: I can add Keys by double clicking the bone then add a key that way, but kinda defeats the whole object of doing so using the trackball rotation system from the GUI
