Question

Hi all,

I've been trying to simply add a ImageDisplay to the tutorial Libriz, but when I'm doing the same as for a GridDisplay, my image is not in the same window...

What I don't understand is that the function that permits me to add a display in my panel is

rviz::DisplayWrapper* wrapperImRGB = manager_->createDisplay( "rviz/Image", "Camera RGB", true );

I've tried to have another render with another manager but still my ImageDisplay is in another window... I really thought that I just had to have another render_panel and everything would be fine...

I know it's really easy, but I'm not used to use ros or qt... Sorry for the inconvenience...

Thanks for the help.

Hi all, I just realised that I have several warning when I'm just compiling the tutorial librviz

I also tried to add a PointCloud2Display in my grid but whitout success. I suspect all the warning but here the code I wrote to add the point cloud in my grid

// Create a PointCloud display.
  rviz::DisplayWrapper* wrapperPC = manager_->createDisplay( "rviz/PointCloud2", "PointCloud Live", true );
  ROS_ASSERT( wrapperPC != NULL );
  // Unwrap it.
  rviz::Display* displayPC = wrapperPC->getDisplay();
  ROS_ASSERT( displayPC != NULL );
  // Downcast it to the type we think we know it is.
  pointcloud_ = dynamic_cast<rviz::PointCloud2Display*>( displayPC );
  ROS_ASSERT( pointcloud_ != NULL );
  // Configure the GridDisplay the way we like it.
  pointcloud_->setTopic("/voxel_grid/out_put");

where pointcloud_ is a member of Myviz and I can see the pointcloud when I'm running rviz. Anyone has already tried what I'm doing or I'm the first one to intend to use this pluggin?

Thanks

I cant display pointcloud2s either! I use the same configuration file for RVIZ as I do for my rviz::VisualizationPanel (or rviz::VisualizationFrame).
