Hi,

The OrientationView Widget of rock does not follow the standard rock
coordinate frame. (x pointing forward, y pointing left and z pointing
up) and the right-handed positive rotation.
http://en.wikipedia.org/wiki/Cartesian_coordinate_system#In_three_dimensions

For example, if we have a negative pitch angle (along Y-axis) following
right-handle positive rotation the widget should depict the pitch up
w.r.t a level position (because is negative) and right now the
representation is down.

Could someone verify this and tell us where is this representation made?

Thanks,

Javier.
