visualizing Pointcloud

Postby basti35 » 08 Jul 2017, 10:32

Hi, I'm trying to show the content of a ros topic of type sensor_msgs/Pointcloud2 into a pointcloud object.
I can't get the function simInsertPointsIntoPointCloud working. What I always get is the error: "One of the function's argument type is not correct.". I tried also to show a list of points defined in the lua (as in the following piece of code), but I got the same result.

Code: Select all

    points = {}
    for i=0,4 do
      table.insert(points, i*0.2)
      table.insert(points, i*0.2)
      table.insert(points, i*0.2)
    end
    simInsertPointsIntoPointCloud(pclHandle,0,points, {100,100,100}, nil)


Is there some example somewhere?

Thanks in advance.

Hello,

your code works perfectly fine. Could it be that your point cloud handle is actually an invalid handle, or a handle to another object? WHat V-REP version are you running?

Cheers

Hello!
There was an issue with my code and the handle was invalid. You're right, it works!
I'm running the 3.4.0.
Thanks for the support.
