Computer Graphics & Simulation Lab

Our research focus is mainly related to applications in personalized health-care, digital prototyping, modeling of mechanical systems, computer games, and robotics. Our work combines advanced mathematical modeling with data-driven approaches, physics and numerical methods. We have a wide range of expertise in numerical solutions of partial differential equations, numerical optimization, computational meshing, geometry processing and more.

Computational Healthcare

Computational Health Care
We work mainly with biomechanical modeling of humans for clinical design. Applications are for decision support systems for prognosis and diagnose of various pathologies as well as systems for progress monitoring for surgical decisions or rehabilitation, and surgical training. Our research topics cover advanced tissue modeling using finite element techniques, statistical models for shape and growth variation, kinematical models of human motion, patient-specific modeling and other topics. We are the coordinator and main PI on the European MSC-ITN RAINBOW, Rapid Biomechanical Modeling for Personalized Clinical Design and we collaborate with companies such as Kitware, 3Shape, Anybody ApS and more.

Robotics

Robotics
Our focus is on robotics simulation and how it can be used for artificial intelligence (AI). We work on soft robots combined with depth range and computer vision systems. Our focus is on creating high fidelity simulators that are extremely computationally efficient. Our research core is on developing novel numerical methods that are highly efficient and exploit modern parallel hardware and on the modeling of constitutive equations such as friction models and stress-strain relationships. Our vision is to make simulation models more data-driven to enable simulators to better bridge the reality gap. We have an ongoing collaboration with NVIDIA working on the FleX simulator, and an MSC-IF EMISSIR project working with multi-level methods.

Digital Prototyping and Computational Mechanics

Digital Prototyping & Contact Mechanics
A large area of focus is on macroscopic friction modeling for simulation of mechanical systems. Applications are a risk assessment of jamming in hoppers or part feeders or similar mechanical systems, robots grasping objects or other kinds of interaction with the environment, and computational fabrication of designed surfaces. Our research involves deriving new novel mathematical models for various frictional effects for various materials such as anisotropic and very stiff materials. The models are derived from micro-scale simulations, or from data-driven approaches where we design measurement equipment and collect data to inspire new models, or from tribology theory about friction models. The focus is fundamental and covers basic research activities in collaboration with other researchers around the world. Examples of our work can be found on our blog.

Films, Computer Games and Innovation

Flamingo Engine Editor
We have a strong and long-term collaboration with the  Alexandra Institute. Through joint positions and projects, we seek to innovate and apply our research in industry. For instance, we have a long-term project on character animation with IO-Interactive and Alexandra Institute. In this work, we supervise industrial PhDs and provide the project with knowledge and experience in frontier research results and skills in solving problems with a scientific approach. We are involved in the national academy of digital interactive entertainment, DADIU. Preparing the next generation of game programmers to use more data-driven models and methods in game production.
