Hi,

I searched your repository but have not found any file related to markers.
Is it possible to visualize arbitrary Markers (http://wiki.ros.org/rviz/DisplayTypes/Marker)?
Especially dynamically spawning and visualizing arbitrary meshes would be valuable.

Cheers,
Bernd

Hi,

is there some migration guide from ROS#?
Those projects seem to be quite similar, despite possible performance improvements and different visualization plugins, right?

Cheers,
Bernd

I'm able to get iviz to connect (Win 10 Unity) to a laptop's roscore (Ubuntu 18.04/melodic).

I've been having issues with other laptops/robots, however, using 14.04/Indigo and 16.04/Kinetic. I run roscore on the laptops/robots and make sure to set ROS_MASTER_URI , ROS_HOSTNAME, and ROS_IP to whichever ip they are assigned (have tried a combination of hostname/ip changes with no success).

On the Unity side, in the iviz UI AR Scene, I get the following error:

RpcConnectionException Error while calling RPC method 'getSystemState' at http://A.B.C.D:11311/ // removed ip from log to post online, I do have this correct though I believe as I can get it to work with a different IP/melodic

I can't seem to pin down the connection issue/don't have a great networking background. I'm guessing this is a ros_comm issue that has changed from kinetic -> melodic. I can't really upgrade my robots sadly. Any idea where to look would be greatly appreciated.

Hi dear,

Firstly i would like to congratulate you on the development of such a game changer app, second i don't know if my question is relevant in this topic so i apologize if it is not.

I have no knowledge of mobile application development so my question is: will the apk for your application be available soon? or would it take the build of the project on unity to output the mobile application?

Regards,
Lotfi

Hi,
The demonstration of iviz on mobile phones is amazing! Many thanks for your awesome work!

I have a question about ROS_HOSTNAME and ROS_IP:

When the ros master is running on the remote robot, the iviz on the phone can obtain ros messages only when ROS_IP is explicitly specified in the robot hosts file. If just ROS_HOSTNAME is set, then mobile iviz can only get the topic list, which seems to be caused by HOSTNAME not being parsed, as shown in the following screenshot. If it is on a PC, this problem can be easily solved by modifying the local Hosts. But it is difficult to modify Hosts files on Android. Is there a way to directly resolve ROS_HOSTNAME through iviz without specifying ROS_IP in the robot?

Hi,

A problem occurred when I tried to add an AR module:

How to solve it? Thanks.

Thanks for your great jobs, I succesfully made it run in androud phones with ROS melodic. Really nice work!

I wonder if iviz will support ROS2?

And how can we download the app for the iphone or ipad?

Hi,
your work looks very interesting and promising. We want to use iviz with the HoloLens 2. Did you ever run iviz on a HoloLens?
Right know I was not able to build iviz for UWP platforms, I couldn't even import MRTK in the project.
Do you have any suggestions?

Hi everyone,

How can I build a different version of Iviz application in 2D mode to visualize 2D map from laser scan data only?
Thank you guys pretty much.

Hi there,

first of all: great job on this project!
I tried to run iviz on Ubuntu 20.04 with Unity 2019.4.23
When adding a Pointcloud2 topic, I got the follwing error on clicking the topic:

any leads/suggestions how to solve it?

Hey, I downloaded the project today and ran it on Unity 2020.3.3f1. I connected to a different PC that was running a SLAM algorithm on ROS and wanted to visualize the generated point cloud using iviz. The topic I need showed up and I chose it, but I didn't receive any messages on it. I even tried disabling the firewall and echoing the topic in iviz but still nothing. The PC running Unity is running on Windows 10, and the ROS-running PC is on Ubuntu 18.04. Any idea what I might be missing? Thanks

Thank you for your hard work and selfless dedication. I have benefited a lot from this project. But during this period, the program cannot run with the following error:

[NtpChecker] Failed to read NTP clock from the master.System.IO.IOException: Failed to contact host '192.168.1.120'
at Iviz.Ntp.NtpQuery+d__1.MoveNext () [0x00111] in /Users/akzeac/Documents/iviz/iviz_ntp_lib/NtpQuery.cs:44

Looking forward to your reply, thank you。

Thanks for your great job!

My attempt on Windows10 was unsuccessful since the wired connection beteween robot and laptop wire seemed unstable (sometimes the connection can be successful, but most of the time It keeps retrying). So I considered using IVIZ in Ubuntu, but an error occurred when I started UI AR according to the process:

Assets/Application/Controllers/OccupancyGridListener.cs(4,22): error CS0234: The type or namespace name 'Remoting' does not exist in the namespace 'System.Runtime' (are you missing an assembly reference?)

How should I solve this problem?
Thank you!

Hi, i followed the step to open the project in Windows and Unity 2019.4.431f1. I opened the scene UI AR and i press play button. I get the following error: the variabile grandparentCamera of CameraOverlayDisplay has not been assigned. In the screen of app Iviz when i press any button nothing happens.

Hi, thanks for contributing this work for ROS community.
I could not find the apk of android iviz. I found it in log here(https://github.com/KIT-ISAS/iviz/tree/5798e1e17462b20ef3f142f5f3ba70a9910a7f0a/iviz/Binaries). Where is latest apk location in this repo? Thanks

Thank you for your great work. I am trying to import my own robot model to Unity. However, the model failed to be imported with errors. My computer is running win10 and I create a ros_package_path file at c:/users/account/.iviz/ros_package_path. I also enable model service in the setting.

Can this also use an ArUco Tag or similar as reference for the Augmented Reality, instead of just using a surface?
