Realistic Object Relighting (WiSe 2025/26)

Project Description:

With this project, we would like to gain hands-on experience with the reconstruction of relightable 3D scenes. This involves not only the computation of scene geometry, but also the correct separation of lighting information and object material properties. 

Building upon the insights gained during the summer term project entitled “Realistic Relighting of Point Clouds”, this semester we will investigate practical ways to quickly capture environmental maps in order to better support the disambiguation between lighting and material properties. 

We want to focus our attention on exploring state-of-the-art relighting methods for various geometric representation such as triangular meshes and 3D Gaussians. As a part of the practical experience, we will also generate our own 3D reconstructions of real-world objects varying in complexity with respect to their geometric and material properties. This will allow us to systematically analyze and compare the chosen relighting algorithms and identify their limits.

In the later stages of the project, we want to focus on design and implementation of possible algorithms modifications aiming to overcome some of the limits identified during the algorithm testing stage. While the accurate material estimation remains the main goal, algorithm improvements for the sake of computational or rendering efficiency will also be considered as a secondary objective.
