Havard,
We do not yet have centralized documentation for all meshing related data objects, though you can see the code comments for the datatypes the
VertexMesh and EdgeMesh and their IMesh superclass in the org.eclipse.eavp.modeling bundle and an example of working with them (the EAVP Mesh Editor) in the org.eclipse.eavp.javafx.mesh bundle. We have documentation related to using the Mesh Editor
on the wiki and the MeshEditorTutorial in the docs folder of the
ICE repo, but these are related to using EAVP's default Mesh Editor rather than setting up your own.
In the ICE repo you can find VisualizationCompleteModel in org.eclipse.ice.demo, which shows how the EAVP Mesh Editor can be instantiated, but it uses an ICE specific class (MeshComponent) that isn't available in EAVP.
You can see an example of a mesh being changed in real time
here. I should mention that moving vertices with the mouse as seen in the video is a function of the FXMeshViewer (a part of our default Mesh Editor implementation) and not of the core EAVP data structures themselves.
Here is an example of setting up a truely minimal FXCanvas of your own.
//Get the ControllerProviders from the factory. We would normally get this factory from the IVizService, but we instantiate it here for simplicity.
FXMeshControllerProviderFactory factory = new FXMeshControllerProviderFactory();
IControllerProvider<FXVertexController> vertexProvider = factory.createProvider(new VertexMesh());
IControllerProvider<FXEdgeController> edgeProvider = factory.createProvider(new LinearEdgeMesh());
//Create a vertex at the origin
VertexMesh vertexMesh1 = new VertexMesh();
FXVertexController vertex1 = vertexProvider.createController(vertexMesh1);
vertex1.updateLocation(0.0, 0.0, 0.0);
//Create a second vertex at (100,100)
VertexMesh vertexMesh2 = new VertexMesh();
FXVertexController vertex2 = vertexProvider.createController(vertexMesh2);
vertex2.updateLocation(100.0, 100.0, 0.0);
//Create an edge connecting the two vertices
LinearEdgeMesh edgeMesh = new LinearEdgeMesh(vertex1, vertex2);
FXEdgeController edge = edgeProvider.createController(edgeMesh);
//Get the Groups containing the pieces' JavaFX shapes
Group vertex1Group = (Group) vertex1.getRepresentation().getData();
Group vertex2Group = (Group) vertex2.getRepresentation().getData();
Group edgeGroup = (Group) edge.getRepresentation().getData();
//Add the groups to your FXCanvas as normal...
//Animate the edge by moving its endpoint
vertex2.updateLocation(200.0, 200.0, 0);
To create a more complex shape, simply start adding more vertices and connecting them with edges, as seen above.
