ArtLang: Structured Language-to-Kinematics Grounding for Articulated 3D Actuation
Sylvia Yuan, Dan Wang, Ravi Ramamoorthi +1
Articulated-object reconstructions recover explicit geometry and kinematics, but their parts often remain semantically anonymous and must be controlled through part indices and num…
ArtMesh: Part-Aware Articulated Mesh Fields with Motion-Consistent Dynamics
Sylvia Yuan, Dan Wang, Ravi Ramamoorthi +1
We present ArtMesh, a mesh-native method for reconstructing articulated objects explicitly as connected triangle meshes with per-part rigid motion from multi-view images in start a…
Instant Expressive Gaussian Head Avatars at Over 100 FPS
Kaiwen Jiang, Xueting Li, Seonwook Park +3
Portrait animation has witnessed tremendous quality improvements thanks to recent advances in video diffusion models. However, these 2D methods often compromise 3D consistency and…
MS-GS: Multi-Appearance Sparse-View 3D Gaussian Splatting in the Wild
Deming Li, Kaiwen Jiang, Yutao Tang +3
In-the-wild photo collections often contain limited volumes of imagery and exhibit multiple appearances, e.g., taken at different times of day or seasons, posing significant challe…
A Generalizable Light Transport 3D Embedding for Global Illumination
Bing Xu, Mukund Varma T, Cheng Wang +5
Global illumination (GI) is essential for realistic rendering but remains computationally expensive due to the complexity of simulating indirect light transport. Recent neural meth…
Differentiable Light Transport with Gaussian Surfels via Adapted Radiosity for Efficient Relighting and Geometry Reconstruction
Kaiwen Jiang, Jia-Mu Sun, Zilu Li +3
Radiance fields have gained tremendous success with applications ranging from novel view synthesis to geometry reconstruction, especially with the advent of Gaussian splatting. How…
