I'm doing a project with E4 and JavaFX, I want to display a graph using Zest2 but following the example AbstractZestExample need a Stage and do not see how I can use the FXViewer without creating a new scene. I want to put the viewer in a SplitPane in a specified position of the application.
By Alexander NyßenFriend
In GEF4 MVC 0.1.0, FXViewer was responsible for creating the scene, so that your use case can not be realized by using it. We have changed this for 0.2.0 (Mars.1), having exactly this use case in mind, so that the responsibility for creating the scene now lies within the responsibility of the client.
The respective changes to FXViewer are documented in https://wiki.eclipse.org/GEF/New_and_Noteworthy/3.10.1 (Fixed that FXViewer could not share a JavaFX scene) as well as https://bugs.eclipse.org/bugs/show_bug.cgi?id=472646.

I'm trying to create a custom 3D viewer that can show up a rigged model created with blender. Particulary, the model will be a mechanical one, so in need to move them with an IK solver: i ll move/rotate a single bone (which will be the motor axes) and all other components must follow it.
I've already done the Blender part (see link below), but now i'm stuck on how to make a stand-alone viewer (ideally a single executable file) that can communicate with another application/process (maybe with TCP socket?) and move the 3d model based on the information sent by it. I'm working on Win10.
Does anyone have any ideas?
(sorry my bad english, I hope explanation was thorough)

I have a requirement where I need to highlight the buildings around my current location on a map. I am using Xamarin and was wondering if anyone can point me to a correct library or control that can fulfill my requirement.
I am currently using Mapsui for Xamarin but I don't think it has the feature I am looking for.
If you have access to the geometries of the buildings there are many ways you could implement highlighting.
One way that comes to mind. Create a layer on top of your background layer with the same geometries as data source. Use a ThemeStyle to show only the selected geometry. The ThemeStyle class is created with a callback method which determines the style. In that method you should return no style unless the feature id is the same as selected feature id.
You can take a look at the ThemeStyle sample for a more general use of themes (no highlighting).
Also you could look at Mapsui.Sample.Wpf.Editing. Here is a screenshot of that sample:
I am trying to understand how the WebAudio API would work. I have two objects; one representing the listener and one the source. And have used the below link as an example. I am able to move the source and the sound position changes.
https://mdn.github.io/webaudio-examples/panner-node/
The command to change the orientation has been provided: viz this.panner.setOrientation or this.listener.setOrientation. The question I have is: if I have a source or listener object (in canvas mode using ThreeJS viz. we know its position and rotation) how do I change the orientation of either the panner or listener (as the case may be) via JS.
An example would greatly help. Thanks
Any reason not to use THREE's PositionalAudio object? https://threejs.org/docs/index.html#api/audio/PositionalAudio. That lets you add a sound to mesh object, and THREE will take care of moving it. If you want to source a different sound than an AudioBuffer, just connect the audio source to the .gain of the PositionalAudio object.
I'm making an isometric city builder using Monogame Extended and Tiled. I've got everything set-up and now i need to somehow access the specific tiles so i can change them at runtime as the user clicks on a tile to build an object. The problem is, i can't seem to find a "map.GetLayer("Layername").GetTile(x,y) or .SetTile(x,y) function or something similar.
Now what i can do is edit the xml(.tmx) file which has a matrix in it that represents the map and it's drawn tiles. The problem with this is that i need to build the map in the content pipeline again after editing for the changes to be displayed. I can't really build at runtime or can i?
Thanks in advance!
Something like this will get you part way there.
var tileLayer = map.GetLayer<TiledMapTileLayer>("layername");
TiledMapTile tile;
if(tileLayer.TryGetTile(x, y, out tile))
{
// do something with tile
}
However, there's only a limited amount of things you can actually do with the tile once you've got it from the map.
There's no such thing as a SetTile method because changing tile data at runtime is not currently supported. This is a limitation of the renderer, which has been optimized for rendering very large maps by building static geometry that can't be changed once it's loaded into the graphics card.
There has been some discussion about building another renderer that would handle dynamic map changes but at this stage nothing like that has been implemented in the library. You could always have a go at implementing a simple renderer yourself, a really basic one is not as hard as you might think.
An alternative approach to dealing with this kind of problem might be to pre-process the map data before giving it to the renderer. The idea would be to effectively separate the layers of the map that are static from those that are dynamic and render the dynamic tiles as normal sprites. Just a thought, I'm not sure about the details of how this might work.
I plan to eventually revisit the Tiled API in the next major version of MonoGame.Extended. Don't hold your breath, these things can take a lot of time, but I am paying attention to the feedback and kinds of problems people are experiencing with the existing API.
Since the map data is stored in a XML (or csv) file which runs through the Content Pipeline you can not change it at runtime.
Anyways, in a city builder you usually do not change existing tiles but you place object on top of existing tiles.
I am trying to formulate how to create an ADF, drop an object in it, then have that object always be there when I run the app again, after localization occurs, of course. Do I have to save off the locations of virtual objects into a separate file when the user is done "dropping" objects into the scene and then reload them on subsequent runs? Or is there a way to save them into the ADF?
We cannot save objects with ADF, instead while loading ADF, object can be added (after recognition of ADF) to the recognised coordinate.
I did something like this and got it working, but found placed objects oscillating and not get placed exactly on the same place in the subsequent ADF loading. Because whenever Tango connection is established, that location is considered as origin(0,0,0) and objects get placed related to this origin. So it is hard to see those objects exactly on same places.
There's no good way to save it into ADF, unless you hack some of the ADF's meta data. But hacking meta data is not suggested.
I did what you say.
You have to write coordinates of Objects into a separated file then when you reload scene and recognized your room (thanks to the adf), just put back objects at same coords.
Of course every coord (x y z) must refer to the ADF Tango pose -> base = TangoEnums.TangoCoordinateFrameType.TANGO_COORDINATE_FRAME_AREA_DESCRIPTION
On Unity it's very simple, you just have to check to "true" the "Use Area description poses" on your ARCamera tango script and same on your PointCloud script if you use it also.
