Hi, I’m Zhiyuan Ma (马致远), a third year Ph.D. student in the Department of Computing (COMP) at Hong Kong Polytechnic University (PolyU). I am jointly advised by Prof. Lei Zhang at PolyU and Prof. Zhen Lei, Xiangyu Zhu at Institute of Automation, Chinese Academy of Sciences (CASIA).
My research interest is 3D generation.

📝 Publications

Zhiyuan Ma, Xinyue Liang, Rongyuan Wu, Xiangyu Zhu, Zhen Lei, Lei Zhang
- First work to adapt Stable Diffusion as a text-to-mesh generator without 3D data as ground truths.
- Achieved sub-second text-to-mesh generation in 4 steps.
- Introduced only 2.6% more parameters to the original Stable Diffusion model.
