Fracture-Based Cut Computation for Parametrization

Ziyu Wei, Dylan Rowe, Oded Stein

Under Review

We introduce a method for making cuts to manifold surfaces of arbitrary topology in order to make them flattenable for UV parametrization.

SplatPose: On-Device Outdoor AR Pose Estimation Using Gaussian Splatting

Weiwu Pang, Rajrup Ghosh, Jiawei Yang, Ziyu Wei, Branden Leong, Yue Wang, Ramesh Govindan

In Proceedings of the 33rd ACM International Conference on Multimedia Sep 2025

We develop SplatPose, a novel pose estimation technique that uses a data-driven 3D modeling technique called Gaussian Splatting. SplatPose uses a trained Gaussian Splatting model to render an image at an estimated device location, then matches features with the camera image to estimate pose.

Circle Numbers for Multi-Material Surface Completion

Ziyu Wei, Christian Hafner, Aleksei Kalinov, Peter Synak, Chris Wojtan

In Preparation

We present a new algorithm for completing curves or surfaces from partially available boundary data, founded on the idea that each piece of the boundary geometry gives us some confidence that points to one side will lie inside the enclosed object, and points to the other side, outside. The algorithmn can be used in multi-material settins and for various applications such as surface comepetion and point cloud reconstruction.
