The DataVis Lab at Clemson University focuses on the analysis and visualization of large, multifaceted scientific data.
Our research interests include:
  • Topological approaches for scientific visualization
  • Mesh processing for scientific data analysis
  • High performance computing for data visualization
  • Multivariate and ensemble data visualization
We are also part of the Visual Computing Lab at Clemson University.

Congratulations to Guoxi Liu for his paper accepted to IEEE VIS 2023. In this work we apply a producer-consumer paradigm for efficiently computing topological relations on unstructured meshes. The proposed data structure can support scientific visualization algorithms using a fraction of the memory required by other data structures with no loss in time performance.

Congratulations to Xin Xu for his paper published in the International Journal of Applied Earth Observation and Geoinformation. In this work we propose a new algorithm to segment trees in LiDAR point clouds acquired from the ground. Thanks to techniques rooted in computational topology, the proposed approach is robust to noise and requires only one parameter to work as opposed to many user-parameters required by existing methods.

Congratulations to Xin Xu for his paper published in Geoinformatica. In this work we propose a new algorithm to segment trees in airborne LiDAR point clouds. The proposed appproach adopts topological techniques to reduce the effect of noisy samples and improve the segmentation accuracy, speed, and easeness of use.
