Today we are pleased to announce version 3.0 of our WPF Diagrams framework is now available. Download the free trial version from here, or if you are a customer, upgrade from your account page. For those who don’t know, the diagrams framework provides support for rendering and editing diagrams consisting of nodes and connections. The framework includes model diagram classes, visual components and controls for adding and editing the various parts of a diagram. The built-in model componenets can be extended to provide your own business logic, and the visual elements can be fully customized to create stunning effects that suit your application.

Huge Performance Boost

The main addition to version 3.0 is the immensely improved performance. The diagram rendering engine can now support thousands upon thousands of diagram elements. This is mostly noticable by the dramatically improved loading time. All other operations such as panning, editing and exporting have also been improved for large diagrams.

Connection Bridges

Another nice improvement to the framework is the ability to render bridges over intersecting connections. Managing the potentially large number of intersecting points has been made possible thanks to performance improvements mentioned above.

The connection intersections are always calculated, but by default the bridges are not rendered – all you need to do is switch them on. This is done by using a CorneredPathBuilder which is responsible for taking the logical connection model and generating the path geometry. To use this, you create a new connection style in the usual way and set the PathBuilder to be a CorneredPathBuilder with the IsIntersectionBridgingEnabled property set to true. Below is a simple example of how to do this:

<ms:CorneredPathBuilder x:Key="PathBuilder" IsIntersectionBridgingEnabled="True" CornerRadius="0" />
 
<Style x:Key="ConnectionPathStyle" TargetType="Path">
  <Setter Property="Stroke" Value="Black" />
  <Setter Property="StrokeThickness" Value="2" />
</Style>
 
<Style x:Key="ConnectionStyle" TargetType="ms:DiagramConnectionElement">
  <Setter Property="PathBuilder" Value="{StaticResource PathBuilder}" />
  <Setter Property="PathStyle" Value="{StaticResource ConnectionPathStyle}" />
</Style>
 
<ms:FixedStyleSelector x:Key="ConnectionStyleSelector" Style="{StaticResource ConnectionStyle}" />
 
<ms:DiagramFormatter x:Key="Formatter"
                     ConnectionStyleSelector="{StaticResource ConnectionStyleSelector}" />

Last of all you would set the Formatter of the DiagramSurface to be the DiagramFormatter in the code above.

Other Changes

Like most major releases, there are a few breaking changes in Diagrams 3.0. These changes are all very minor and you can see how to work around them in the Release Notes section of the help docs. One change that will most likely impact you is that we removed DiagramSurface.ShowConnectionPoints property. To work around this, you simply don’t need to set this property to True anymore so it can be removed.

Also, as always, there’s a bunch of bug fixes and general improvements.

Get it now!

You can download the free trial version of WPF Diagrams 3.0 from here. Or if you are already a Diagrams 2.0 customer with active subscription, then you can upgrade for free by going to your account page. If you have any questions about this new release you can drop by the forum.

Happy Coding :)

Our WPF Diagrams framework includes a few connection routing algorithms each with different speed and collision-detection preferences. The most impressive router of them all is the AStarPathfinder. As the name suggests, this pathfinder uses the well known A* algorithm to route the connections around all the nodes in the diagram. This algorithm is paired with a custom built data collection which functions similar to a quad-map to minimize the collision detections and thus improve performance.

The first version that was released a couple of years ago performed very well and was great at routing connections while avoid collisions with nodes and minimizing the number of bends in each connection. The main thing that it was missing however is that it did not consider parallel connection collisions. This can easily occur when there are multiple connections on a single node that follow the same path as seen in the image below. This makes it difficult for the user to follow the connections in this kind of diagram.

A little later, we upgraded this path router to consider parallel connections. This was done by updating the A* algorithm to think of clusters of connections as obstacles to route around. This feature is enabled by passing a number into the constructor to specify the desired distance between parallel connections. This produced great results for the customer who requested this feature.

Although the results were great, the performance for much MUCH larger diagrams was almost unusable. There were also some bugs around the ordering of the connections which could cause lots of perpendicular overlaps. Considering each connection cluster as an obstacle to route around was just too much for the algorithm to handle. So we reverted the connection considerations and did some research into a 3-phase routing algorithm:

• Phase 1: Create an imaginary grid of horizontal and vertical lines around the nodes.
• Phase 2: For each connection, run the A* algorithm on the grid from phase 1.
• Phase 3: Iterate through each cluster of parallel connections and order/separate them.

The first 2 phases were already in our pathfinder. The problem with the 3rd phase is that it requires the first 2 phases to have already been applied to the entire diagram in order for it to work. This would cause bad performance when dragging a node because all 3 phases would need to be re-run on the whole diagram model. We managed to solve this issue be implementing another custom data collection that could cache the post A* connection paths and very quickly return them for a given area of the diagram. This made it possible to run the 3rd phase only on the parts of the diagram that changed.

The result was a huge boost to both the performance and outcome of the AStarPathfinder on large diagrams such as the extreme case below. (Click on the image to get a better look at the magnitude of the diagram I was using for testing! :-).

Got a diagram with lots of connection that needs a powerful path router? Grab these improvements right now from the current nightly build. Remember to pass in the desired connection separation value into the constructor of the AStarPathfinder your connections are using.

Thanks for reading! Happy coding :)
