Spatiotemporally Consistent Indoor Lighting Estimation with Diffusion Priors
Mutian Tong, Rundi Wu, Changxi Zheng
Indoor lighting estimation from a single image or video remains a challenge due to its highly ill-posed nature, especially when the lighting condition of the scene varies spatially…
Gbake: Baking 3D Gaussian Splats into Reflection Probes
Stephen Pasch, Joel K. Salzman, Changxi Zheng
The growing popularity of 3D Gaussian Splatting has created the need to integrate traditional computer graphics techniques and assets in splatted environments. Since 3D Gaussian pr…
Trust-Region Eigenvalue Filtering for Projected Newton
Honglin Chen, Hsueh-Ti Derek Liu, Alec Jacobson +2
We introduce a novel adaptive eigenvalue filtering strategy to stabilize and accelerate the optimization of Neo-Hookean energy and its variants under the Projected Newton framework…
Stabler Neo-Hookean Simulation: Absolute Eigenvalue Filtering for Projected Newton
Honglin Chen, Hsueh-Ti Derek Liu, David I. W. Levin +2
Volume-preserving hyperelastic materials are widely used to model near-incompressible materials such as rubber and soft tissues. However, the numerical simulation of volume-preserv…
