Rviz time

The VisualizationManager class is the central manager class of rviz, holding all the Displays, Tools, ViewControllers, and other managers. It keeps the current view controller for the main render window. It has a timer which calls update on all the displays. The "protected" members should probably all be "private", as VisualizationManager is not intended to be subclassed.

Add a tool.

Create and add a tool. This will go away in visualization 1. Emitted after a DisplayWrapper has been added and its Display has been created, but before the display is enabled for the first time. Emitted just before a DisplayWrapper is added to the list of displays. Emitted just after a DisplayWrapper is removed from the list of displays, and before it is deleted.

Emitted just before a DisplayWrapper is removed from the list of displays. Emitted by loadDisplayConfig after Displays are loaded. Connect to this signal in order to load your object's state from a Config object when a new display Config is being loaded. Emitted by saveDisplayConfig after Displays are saved.

Connect to this signal in order to save your object's state to a Config object when a display Config is being saved. Emitted by removeAllDisplays just after the list of displays is emptied.

Emitted by removeAllDisplays just before the list of displays is emptied. Return the current ViewController in use for the main RenderWindow. Return the pluginlib::ClassLoader instance to use for loading Display subclasses. Return a reference to the DisplayWrapper array.

Performs a linear search to find the DisplayWrapper holding a given Display. The frame count is just a number which increments each time a frame is rendered. This lets clients check if a new frame has been rendered since the last time they did something. Return the FrameManager instance. Get the PropertyManager which handles Property s of Display s. Return a pointer to the SelectionManager. Return the tool at a given index in the Tool list. If index is less than 0 or greater than the number of tools, this will fail an assertion.

Get the PropertyManager which handles Property s of Tool s. Handle a single key event for a given RenderPanel. If the key is Escape, switches to the default Tool via getDefaultTool. All other key events are passed to the current Tool via getCurrentTool. This just copies the given event into an event queue.

The events in the queue are processed by onUpdate which is called from the main thread by a timer every 33ms. Do initialization that wasn't done in constructor. Sets initial fixed and target frames, adds view controllers and tools, and initializes SelectionManager. Return true if the given DisplayWrapper is currently in the list of displays, false otherwise.

This does not check that the Display has actually been loaded into the DisplayWrapper.

Load the properties of each Display and most editable rviz data. Notify this VisualizationManager that something about its display configuration has changed.This branch is currently contained in the main ros2. The latest release will be available with your ROS 2 download. ROS 2 does not have a wiki yet. The basic documentation can still be found on the RViz wiki page.

For some displays, the documentation is updated. Make sure to read the developer guide below and the migration guide. In RViz for ROS 1 the frames transformation library used is tf2 detailed information about it can be found here. In RViz for ROS 2 the frames transformation library is now pluggable, meaning that different transformation library plugins can be loaded and changed dynamically in the gui. Developers can create and use their own plugins to provide custom transformation behavior.

This plugin is used by default if the tf2 plugin is not available and no other valid plugin is specified. As anticipated, in order for the user to choose the plugin to use, RViz provides a dedicated panel: the Transformation panel. Note: Not all transformation plugins are necessarily compatible with all RViz displays e.

In order to take this possibility into account, the TransformerGuard class is provided. Adding it to a display ensures that the display will be disabled and won't function in case the wrong transformer is used. More detailed information on how to write a transformation plugin and on how to handle transformation specific displays can be found in the plugin development guide.

The simplest way to build from source is to use the official installation guide, since RViz is part of the official ROS 2 repos file.

Note: When building the current ros2 branch from source, the latest ROS 2 release for all dependencies might not be sufficient: it could be necessary to build the ROS 2 master branch. Make sure to have a source build of ROS 2 available see installation procedure above.

The --merge-install flag is optional but ensures a cleaner environment which is helpful for development. Main rationale here is to create code that can be well tested by avoiding highly coupled components. More information on writing plugins can be found in the plugin development guide. Other features: - Filtering of Topic lists by topic type - Message filters - Image transport features.

Currently the latest release beta3 is not sufficient to build rviz so you need to build the ros2 master from source. There will be a setup. The current state of this branch requires a from-source build though. Note Make sure to install all dependencies in either 32 bit or 64 bit version and do not mix.

Dismiss Join GitHub today GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.I am writing an RViz plugin which allows the user to play rosbags and also let's him pause the playing.

The problem with pausing is that the decay time is still the same, so pointcloud data will exceed the decay time even if they should stay while the playing is paused.

Does anybody know how to programmatically change the decay time of this display? Or is there another possibility to hold the current message? Thank you for your answer. I thought it's only available on groovy. At the moment some other functions are more important, but I will come back to your answer the next week. I hope you're still open for questions then, if neccessary I've just found another method to set the display parameters: In your plugin class override onInitialize it doesn't need to do anything, just override it.

The VisualizationManager contains several useful instances, like a ViewController and all the displays you are working with. You can then get the required display and change parameters. If you have any other questions, feel free to ask. Your question might be valid though. Have you tried using the --clock option for rosbag play? More info for clock. RViz does obey this. If the laser decay time does not, please file that as an issue.

Could you explain that? RQT just loads RViz as a subwindow, it should open your default config. The decay time is still in the Laser Display options.

Does RViz show any warning or error? Check with rxgraph if and for which topics rosbag and rviz are connected. If you mean how to enable --clock for RQT-bag I don't see it. I think it's not clear enough what the problem is. The rosbag plays perfectly fine on RViz. But as soon as I pause the rosbag play process, the last published message will disappear due to the decay time.

What I want to do is set the decay time programmatically.

How can RQT help me doing that? How does this help showing the messages? Thanks for helping though. Aaaaaaah, now I get it Thank you very much, that really helped! Now a final question: Is there a way to clear the screen after rosbag has played? I'm no RViz dev, but never saw something that simulates the reset button except for markers.RVIZ is a ROS graphical interface that allows you to visualize a lot of information, using plugins for many kinds of available topics.

To be able to visualize the information published by the ZED camera, it is necessary to correctly configure the Global Options :. By expanding the Links voice, you can see the whole model tree, with all the joints and the links available and the relative position and orientation in the space relative to the fixed frame.

This plugins allows you to visualize the position and the orientation of all the frames that compose the TF Hierarchy. This allows you to concentrate only on the parts that are most important for your current task. To create your own RVIZ configuration, you can use the plugins described below. Global options To be able to visualize the information published by the ZED camera, it is necessary to correctly configure the Global Options : Key parameters: Fixed frame : Indicates the name of the frame used as reference for all the other frames.

You can select every frame available in the combo box. Frame rate : The maximum frequency used to update the 3D view. Available computational power should guide your decision. Grid This plugin allows you to visualize a grid normally associated with the floor plane. TF This plugins allows you to visualize the position and the orientation of all the frames that compose the TF Hierarchy.Contents Turning off hardware acceleration Problems you may encounter Help!

[ROS Q&A] 122 - How to show laser data on Rviz

There are generally three reasons for failure along these lines: You don't have a tf transform tree set up. Find a node that is supposed to be running but actually not, by following steps. Run the following. You have a transform tree. Make sure the Fixed Frame is set to a frame that exists in your system. You can use the TF Display to help see if you have your frames set right. You have a transform tree, and the Fixed Frame exists in it. This is often a timing or frame problem.

See the tf troubleshooting page for more information. Another common reason for nothing showing up is if the data being displayed is not visible from your current view. I have seen two causes for this apparent lack: Running rviz remotely which is not supported Version mismatch between libGL. More details and a fix for the mismatch are at ROS Answers - rviz-in-ros-electric.

This means you don't have OpenGL support available. Running through a virtualization environment that does not support hardware accelerated 3D is a common cause of this, as is not having the correct drivers installed under Linux. In general, if there are proprietary graphics drivers for your hardware in Linux, use them instead of the non accelerated open source ones. One of them seems to relate to the render-to-texture system. Ogre supports 3 different modes, and rviz uses the "PBuffer" mode by default.

Some users have reported some modes cause a segfault during startup, but it is not clear which should be used when. Probably, the GL driver refused to create the texture. Fixed in version 0. The callstack for this crash looks similar to: 0 0xfebda8b in?? In both cases, the error is fatal but intermittent. This is a symptom of a known bug when RViz is used with certain video cards.

See Section 2. There are two workarounds you can try. This setting changes some of the internal details of how the window is rendered. Second, since the problem is intermittent, you can simply try starting RViz again and again until it succeeds. For more detail, see this ticket Multiple Monitors Some graphics drivers don't like when a 3D accelerated application spans multiple monitors.

Some drivers even only accelerate the primary display. In either of these cases rviz may become slow or unresponsive. In the first case, simply prevent the 3D window from spanning multiple monitors.

In the second, open rviz on your primary display. How to make a usable bug report If you haven't found a solution on this page, on ROS Answersor a Google search the Ogre3D package has a great discussion forum for instanceplease follow these instructions when reporting a bug. We need a lot of data about a crash or other failure in order to understand the cause. Please include as much of this data as you can. Include the output of this.
