2015-11-19 22:26:07 -0600 answered a question Getting bounding box of model(object)

i just find it on gazebo source code ^^ $ grep "boundingbox" * -ri

use below code:

gazebo::rendering::ScenePtr scene = gazebo::rendering::get_scene();
rendering::VisualPtr visual = scene->GetVisual("your model name");
math::Box boundingBox = visual->GetBoundingBox();

2015-11-18 01:17:06 -0600 asked a question How can simulation multi-layer(vertical) using gpu_ray sensor?

I would like to simulate the Velodyne Laser.

Velodyne sensor vertically and horizontally in a number of Ray information has to be obtained. So, I try to implement as Ray Sensor Plugin, but is very slow.

So, I replace it with a Gpu Ray sensor parameter setting the vertical ranges does not operate. It operates only when set to 1, the Vertical ranges. Is this a bug? All Gpu Ray sensor test code Vertical ranges equals 1.

The following questions look conclusions should be implemented by rotating the Horizontal Laser sensor. http://answers.gazebosim.org/question...

It does not occur under Issue seems. https://bitbucket.org/osrf/gazebo/iss...

Are there any ideas?
