This is "Connector", a sort of visual debugging or data browsing tool for the Verse network platform. Connector was written by Eskil Steenberg. The Verse homepage is at <http://www.blender.org/modules/verse/>, and the project page at Blender, where you can find out how to access the code in CVS, is at <http://projects.blender.org/projects/verse/>. The following documentation is by the author, Eskil (slightly edited): --- * --- Connector Connector is a Verse application that lets you view and modify Verse data using a schematic view. You can create, delete and modify all Verse nodes, it includes built-in editors for the material node as well as for the curve node. USAGE Connector has a special interface that is somewhat different from other applications, but it has been designed to be easy to use (at least easier relative to my other apps). Connecting Once you have started Connector you will see a short animated intro. At any time you can click anywhere in the window to display the connect interface. Either you can click on "localhost", to connect to a local host, or you can type in the address of a non-localhost (IP address or DNS name) and name and password if needed. Switching Modes Once you have connected, you find yourself viewing a white desktop. This is where you can arrange your nodes and view their links. At the moment it is empty because you need to select some nodes to work with. In order to do this you must go to the node list. Click in empty space to switch to the node list. Now some nodes will appear. To get out of a node simply click in empty space in the node list to return to the desktop. Node List In the node list, all nodes on the host are visible in rows from top to bottom. The nodes are visualized as circles that look like different planets. Each node type is visualized as a different type of planet. For instance object nodes are visualized as suns, and geometry nodes are Saturn-like planets with rings surrounding them. By clicking on one of the nodes, you return to the desktop but now the node is available on the desktop. In each node you can also read the name of the node. The top row of nodes are actually not real nodes but if you click on one of them you will create a new node and show place it on the desktop. If you have nodes they wont all fit on the screen at once so in order to scroll the list up or down, simply click and drag the background. Note that there is a difference between clicking on the background (to return to desktop) and dragging the background (to scroll). By clicking on a node in the node list using the middle mouse button, you display it on the desktop without actually returning to the desktop. The Desktop Once you return to the desktop you can rearrange your nodes by clicking and dragging them. You can also scroll the desktop by grabbing it and dragging it. If you grab the desktop at the far left or right edge of the window you can zoom in and out of the desktop.
