Wow! And it seems to be relatively fast. Well done!

you can now place the label on the bottom left of an element.

The behavior is still odd. If I change the previous code to 10 visualize ten arcs:
view := RTView new. shape := RTArc new innerRadius: [ :i | i *50]; externalRadius: [ :i | (i * 50) + 4];
alphaAngle: 45; betaAngle: 135; color: Color black.elems := shape elementsOn: (1 to: 10). view addAll: elems.
label := RTLabelled new text: #yourself. label left. elems @ label.
view
The result is this:<labels2.png>
I think this happens because it is trying to put the label at the left-center of the arc (encompassing rectangle?). There is a way to put it at the left bottom?

Looks somewhat odd, still, when you change the angles:
view := RTView new. shape := RTArc new innerRadius: [ :i | i *50]; externalRadius: [ :i | (i * 50) + 4]; alphaAngle: 315; betaAngle: 45; color: Color black. elems := shape elementsOn: (1 to: 2). view addAll: elems.

Hi
There was a problem in #encompassingRectangle in TRArcShape, try again with the last version of Roassal

2015-05-20 13:51 GMT-04:00 Miguel Campusano mcampusa@dcc.uchile.cl: Following this, I tried to add labels to the arcs but It is not working as I expected. My code:
view := RTView new. shape := RTArc new innerRadius: [ :i | i *50]; externalRadius: [ :i | (i * 50) + 4]; alphaAngle: 45; betaAngle: 135; color: Color black. elems := shape elementsOn: (1 to: 2). view addAll: elems.
label := RTLabelled new text: #yourself. label left. elems @ label.
view
and the results is the attached image.<labels.png>
I want the labels to be at the left of the arc line. Maybe I'm doing something wrong? any ideas?
Bests, Miguel

The visualization shows an object with the red line and a grid to understand quickly the position of the object within the range of the sensor (This case, the object is approximately in the center between 2 to 4 meters from the robot) . The visualization is dynamic, ie: the red line is automatically updated overtime ;) <laserscan.png>
