Algorithms for Computer Graphics

In 3D assisted simulation and test environments, it is often required to interactively navigate in highly complex 3D scenes that are partly generated at run time. To render such 3D scenes in real time, we develop rendering algorithms that reduce the amount of data to be processed in such a way that fluent navigation is possible.


The “DigiChemLab” project aims to develop a virtual learning platform for chemical-technical education using virtual reality technology. It represents a supplementary offer for students to prepare for internships in chemical laboratories, for example. The overarching goal is the integration of digital collaboration formats in teaching and studying.

Chemistry Lab

An exemplary “laboratory” use case in the technical environment looks like this: Students are to carry out an experiment in a virtual laboratory according to the instructions in their teaching materials. To do this, they enter the virtual lab with the VR headset. They interact with the 3D world with the help of two controllers that they have on their hands. With these, they can grasp and operate objects in the 3D world. For an experiment, they take the necessary devices out of cupboards, place them on the virtual work table and prepare their use. Materials are processed virtually with the devices, and experimental trials can be carried out in the virtual world. The student also receives assistance or instructions on how to conduct the experiment correctly from the VR system. Accordingly, the VR system can react interactively to the student’s actions. A virtual experiment can be carried out by several students or lecturers in the room. The persons meet in the 3D room, see each other as avatars and communicate with each other.

Modelled working environment

An interesting aspect here is that the people acting in the virtual lab can be in different locations in the real world. This is also about designing new mobility patterns (virtual and mixed mobility) and improving digital and intercultural skills.

Together with partners from chemistry, we are developing the necessary VR environment and are trying to make it available as an infrastructure so that it is possible for users without domain-specific knowledge from the VR field to set up corresponding laboratory environments.

Automatic generation of landscapes based on road data

For virtual simulation environments, it is often necessary to
create large, complex 3D landscapes. The manual creation of
such landscapes is often very time consuming and expensive.
In cooperation with dSPACE GmbH by the Software Innovation
Lab of Paderborn University, we develop methods for automa-
tically generating landscapes for driving simulations. The goal
is to generate fitting, plausible landscapes based on raw road
data that can be used for virtual driving simulations.
