Point-Based 3D Reconstruction from Sparse Views under Known Illumination
Magnus Kaufmann Gjerde, Joakim Bruslund Haurum, Jeppe Revall Frisvad +3
Sparse view 3D reconstruction is commonly addressed with neural implicit surfaces or dense point-based representations such as Gaussian splatting. Surface-aware splatting methods i…
Differentiable Voxelization of Surface Representations
Tobias Djuren, Ugo Finnendahl, Markus Worchel +2
Different shape representations facilitate different computations. Surface representations, in particular meshes, are often used for modeling, whereas volume representations are us…
As-Rigid-As-Possible Regularization for Implicit Surfaces
Tobias Djuren, Markus Worchel, Ugo Finnendahl +1
Implicit surface representations have regained popularity because of their use in machine learning. A common component in optimization is regularization, penalizing the deviation o…
Radiative Backpropagation with Non-Static Geometry
Markus Worchel, Ugo Finnendahl, Marc Alexa
Radiative backpropagation-based (RB) methods efficiently compute reverse-mode derivatives in physically-based differentiable rendering by simulating the propagation of differential…
