seems reasonable :D<br>
<br>
no, seriously: currently i don't have an imu, but i think i remeber
this occured also on the sauc-e but we ignored this... (or added an
- sign to the widget)...<br>

<pre>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.
<a moz-do-not-send="true" class="moz-txt-link-freetext" href="http://en.wikipedia.org/wiki/Cartesian_coordinate_system#In_three_dimensions">http://en.wikipedia.org/wiki/Cartesian_coordinate_system#In_three_dimensions</a>
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.
