Re: [eavp-dev] EAVP architecture
|
Torkild,
We don't currently have any documentation on the high level architecture of the project. However, here's a quick explanation. Capabilities in EAVP are added by realizing the IVizService interface. The IVizService will create an ICanvas (for parts the user will interact with heavily) or an IPlot (for parts which exist mostly just to display a visualization of a pre-existing file.) These will in turn draw whatever is necessary in a Composite you give them. These IVizServices can have a many-to-one relationship with the rendering engines. For example, JavaFX has both the FXGeometryVizService for a 3D shape editor and the FXMeshVizService for a 2D mesh editor. By contrast, VisIt has just one, because we don't do anything with VisIt except send it files and user input from ICE and receive images back from it to display. How a rendering engine is used is left to the individual IVizService, with, for example, JavaFX code simply being called in EAVP classes and ParaView being run as its own separate instance that EAVP communicates with.
ParaView's code is going to be receiving a lot of maintenance this week, and Jay may be able to tell you more about plans for longer term development.

Subject: [eavp-dev] EAVP architecture
Hi guys,
I’m curious about the EAVP architecture, in particular how various rendering engines are plugged in. JavaFX 3D vs ParaView for example. I’ve been looking around but cannot find documentation on this, is there any? Also what are the plans for supporting ParaView? I believe this feature is in particular interesting.
Best regards,
Torkild
