报告题目：Efficient Representations for 3D Generative Modeling
报告摘要：
This presentation delves into the world of 3D generation models, with a spotlight on the critical significance of representations and data structures. We will survey a range of representation methods and data structures across voxel-based, mesh-based, point cloud-based, and implicit function-based domains, shedding light on their respective merits and applications. Alongside addressing the delicate balance between accuracy and efficiency, I will also share my own contributions, demonstrating how my work intersects with these foundational components. This talk will include our publications 3DILG in NeurIPS 2022 and 3DShape2VecSet in SIGGRAPH 2023.

报告题目：SDF fields meet 3D shape generation
报告摘要：
Easily creating 3D shapes to fit human’s fabulous imaginations and match the designer’s creative ideas is one of the ultimate goals in computer graphics. The rapid development of generative neural networks, such as generative adversarial networks, diffusion models, autoregressive networks, and flow-based models, achieves great progress in text, image, and video generation. These techniques have been adopted for generating 3D shapes with different kinds of 3D representations and greatly reduce the workload of 3D generation. However, there exists a large quality gap between the synthesized shapes and the dataset the generator was trained on. Moreover, existing approaches lack intuitive control and convenient ways to control the shape generation process to satisfy users’ intentions. This talk will cover two works, the first is SDF-StyleGAN, a StyleGAN2-based deep learning approach for 3D shape generation, with the aim of reducing visual and geometric dissimilarity between synthesized shapes and the shape collection, and the second is LAS-Diffusion, a diffusion-based 3D generation framework to model plausible 3D shapes via 2D sketch image input.
