Nav_msgs/Path Message Problem

Hi there,

I tried to visualize nav_msgs/path messages on ros-rviz. When i made it on Rviz, there is no problem with visualization. It looks like : https://ibb.co/gyV7pCM However when i tried to visualize it via ros-rviz, lines and markers visualizations' are failing. (https://ibb.co/5rr5w6t) What can cause to that? Any idea how to visualize nav_msgs/Path messages in a proper way ? You can find the code i added for Ros-rviz-path below. I also added related things to ros-rviz.html and ros-rviz-display.html.


`

<script> Polymer({ is: 'ros-rviz-path',

  properties: {
    globalOptions: Object,
    isShown: Boolean,
    name: {
      type: String,
      value: 'Path',
    },
    ros: Object,
    tfClient: Object,
    topic: {
      type: String,
      value: '/Visualization_path',
      notify: true,
    },
    viewer: Object,
    _path: {
      type: Object,
      value: null
    },
  },

  observers: [
    '_optionsChanged(viewer, topic, ros)',
  ],

  destroy: function() {
    // Nothing to destroy.
  },

  // TODO: all "destroys" should just be detaches
  detached: function() {
    this.hide();
  },

  hide: function() {
    if (this._path) {
      this._path.unsubscribe();
    }
  },

  show: function() {
    if (this._path) {
     
      
    }
  },

  _optionsChanged: function(viewer, topic, ros) {
    this.hide();
    this._updateDisplay();
  },

  _updateDisplay: function() {
    if (!this.viewer || !this.topic || !this.ros) {
      return;
    }

    var that = this;
    
this._path = new ROS3D.Path({
  ros: this.ros,
  topic: this.topic,
  tfClient: this.tfClient,
  rootObject: this.viewer.scene,
  
});


    
    
  },
});

</script> `

Hi @mhakca,

It's a bit hard to tell just by looking at this.
Have you tried checking what RViz does to show the paths? That might give you a clue in case there's any correction to apply.

Hi there, problem is still existing. I saw that there is no problem with path visualization. Situation is that, i need to visualize 4 paths, 2 markers, 1 robot model and 1 marker array messages. I can visualize some combinations without any problems like 2 markers,1 robot model, 1 marker array or 2 paths,1 markers, 1 robot model, 1 marker array etc. When i tried to visualize more than that system becomes problematic. Problem is that everything on screen acts for different times. For example, 1 path message acts the move in 10th second other path message acts the move in 8th second and at the same time marker acts the move in 7th second. What can cause to that problem any idea ? You can see the screenshot of the viewer when it works in proper way with 2 path messages, 1 marker and 1 marker array
