Our group develops software frameworks in different research and application areas which contribute essentially to our research projects. Please find an overview of our current developments here.

Avango/Guacamole

Avango/Guacamole is a Python/C++ framework for the development of complex virtual reality applications. It provides

  • a modern scene graph,
  • rapid application development in Python,
  • support for various input devices,
  • an efficient multi-GPU rendering back-end for different geometry types (including large point cloud rendering based on Lamure),
  • 3D-reconstructions from RGBD-sensors,
  • a programmable shading-pipeline for sophisticated rendering effects,
  • and a network-distribution layer.
