rqt_pose_view's Issues

Parameter for topic to subscribe to

Hi, I think it would be useful to have an optional node parameter for which topic the node should listen to for Imu messages. Then it will be possible to put pose view in a launch script without having to do the topic drag-and-drop manually while running. Thoughts?

Axes mixed up?

I just tested pose view with a sequence of simple rotations, and the box in the visualization appears to rotate the correct amount around the correct axis, but in the wrong direction.

These are the rotations I tried and the results I got:

roll	pitch	yaw	q.x	q.y	q.z	q.w	result	expectation
15°	0	0	.13	0	0	.99	neg. roll	pos. roll
0	15°	0	0	.13	0	.99	neg. pitch	pos. pitch
0	0	15°	0	0	.13	.99	neg. yaw	pos. yaw
-15°	0	0	-.13	0	0	.99	pos. roll	neg. roll
0	-15°	0	0	-.13	0	.99	pos. pitch	neg. pitch
0	0	-15°	0	0	-.13	.99	pos. yaw	neg. yaw

I'm assuming that the colors in pose view are (red = x), (green = y), (blue = z), and that it uses right-handed rotations. Is that correct?

(I used http://www.andre-gaschler.com/rotationconverter/ to calculate quaternions to test based on roll/pitch/yaw values. Since the rotations are simple, Euler angle convention should not matter, but I had it set to ZYX.)

Attempt to set a screen on a child window.

I try to run it like this:

rqt --standalone rqt_pose_view

I directly get these error or warnings:

and when I try to drag and drop any topic from:

rqt --standalone rqt_topic.topic.Topic

I get this error:

PoseViewWidget.dragEnterEvent(): event.source() has no attribute selectedItems or length of selectedItems is 0
