⌨️ About Me

Welcome to Zhenyu’s website!

I am Zhenyu Sun, a graduate of South China University of Technology (SCUT), where I earned a GPA of 3.97/4.00 (rank:1/76)).

Here is my CV for specific information.

My research so far has concentrated on Next-Generation 3DV, aiming at exploring modern 3D/4D Foundation Architecture, while enhancing the spatial intelligence.

I will spend the Ph.D journey supervised by esteemed Prof. Yuanbo Xiangli, in SAI, SJTU, from 2026 fall！

CGGS: Consistency-Augmented Geometric Gaussian Splatting for Ego-centric 3D Scene Generation

Zhenyu Sun, Xiaohan Zhang, Qi Liu*, Huan Wang*

• We propose CGGS, a new framework for ego-centric 3D scene generation from textual description. With the novel insight in MV-LDM and 3D Gaussian optimization, our method surpasses previous counterparts in terms of semantic alignment, perceptual quality, and rendering fidelity when producing realistic, domain-free 3D scenes.

GarmentX: Autoregressive Parametric Representations for High-Fidelity 3D Garment Generation

Jingfeng Guo, Jinnan Chen, Weikai Chen, Zhenyu Sun, Lanjiong Li, Baozhu Zhao, Lingting Zhu, Xin Wang, Qi Liu*

• We propose GarmentX, an image-guided 3D garment generator that produces editable garment parameters, decodes valid sewing patterns, and simulates wearable 3D garments. By adjusting garment parameters, users can easily modify the shape, style, and even category of the garments. The generated garments are diverse, high-fidelity, and physically plausible.

Toy-GS: Assembling Local Gaussians for Precisely Rendering Large-Scale Free Camera Trajectories

Xiaohan Zhang, Zhenyu Sun, Yukui Qiu, Junyan Su, Qi Liu*

• We propose Toy-GS, a novel method that adaptively assembles local Gaussians to enhance rendering quality and reduce GPU memory usage for large-scale free camera trajectories.

ArXiv 2024

Aerial-NeRF: Adaptive Spatial Partitioning and Sampling for Large-Scale Aerial Rendering

Xiaohan Zhang, Yukui Qiu, Zhenyu Sun, Qi Liu*

• We propose Aerial-NeRF with three innovative modifications for jointly adapting NeRF in large-scale aerial rendering. Our model allows us to perform rendering over 4 times as fast as compared to multiple competitors.
