The aim of this project is to investigate and to contribute to shape modeling and geometry processing for personal fabrication---a trend that currently receives intensified attention in the science and industry. Our goal is to contribute novel algorithmic solutions for fabrication-aware shape processing and interactive modeling. In particular, we want to research following aspects: (i) We want to address the currently pending problem of high-level shape understanding, (ii) we want to research novel high-level shape modeling methods for interactive creation of plausible and aesthetically appealing shapes, and finally, (iii) we want to address optimization problems related to instant desktop 3D printing, such that modeled objects can be directly fabricated. The outcome of the project will be a set of algorithmic solutions for high-level shape modeling for instant personal fabrication.

Research Areas

  • The advent of consumer-grade 3D printing has recently sparked interest in fabrication-aware shape design and optimization. We use techniques from computer graphics and engineering to develop new computational tools to facilitate the design process of physical artifacts.

We present Points2Surf, a method to reconstruct an accurate implicit surface from a noisy point cloud. Unlike current data-driven surface reconstruction methods like DeepSDF and AtlasNet, it is patch-based, improves detail reconstruction, and unlike Screened Poisson Reconstruction (SPR), a learned prior of low-level patch shapes improves reconstruction accuracy. 
Note the quality of reconstructions, both geometric and topological, against the original surfaces. The ability of Points2Surf to generalize to new shapes makes it the first learning-based approach with significant generalization ability under both geometric and topological variations.
