VaMEx-RGE working meeting

From 29.08. – 31.08. an internal RGE working meeting took place at the University of Bremen. Participants were members of the working group for Cognitive Neuroinformatics, the working group for High-Performance Visualization and DFKI. At times, Andre and Roland from the Computer Graphics and Virtual Reality working group were also present. Together, we clarified many questions on key areas such as SLAM, trajectory planning, VTB connection, mission control and the network architecture.

We see the first deployment of two ubiquity access points as a special milestone. This enabled us to send the first ROS2 messages via a network between the two access points.

Other highlights included a visit to the “MARS findet Stadt” exhibition at the Kulturkirche St. Stephani and dinner at the Pannekoekschip Admiral Nelson.

New Node editor plugin library for CosmoScout VR released

In order to enable the interactive analysis of satellite data in the Mission Control tool in the medium term, a new plugin library for CosmoScout VR has been developed in recent weeks. The plugin library allows to model complex data flows using a node editor.

The node editor uses a web server that provides a web page on a specific port via HTTP. The user can access this frontend with a web browser and start creating a node diagram. For each node or connection created, a C++ counterpart is instantiated by the plugin library.

All data flow takes place on the C++ side, the web frontend is “only” a visualization of the graph. This separation allows the graph to be displayed both in the UI of CosmoScout VR (since the UI is rendered using web technologies) and on external devices.
