Double-Freeform Lens Design for Angular-Spatial Control of Light Fields
Yuou Sun, Bailin Deng, Juyong Zhang
Precise simultaneous control of both angular and spatial light-field distributions remains a longstanding challenge in optical design, often requiring complex multi-element configu…
Computational Caustic Design for Surface Light Source
Sizhuo Zhou, Yuou Sun, Bailin Deng +1
Designing freeform surfaces to control light based on real-world illumination patterns is challenging, as existing caustic lens designs often assume oversimplified point or paralle…
Shape from Semantics: 3D Shape Generation from Multi-View Semantics
Liangchen Li, Caoliwen Wang, Yuqi Zhou +2
Existing 3D reconstruction methods utilize guidances such as 2D images, 3D point clouds, shape contours and single semantics to recover the 3D surface, which limits the creative ex…
End-to-end Surface Optimization for Light Control
Yuou Sun, Bailin Deng, Juyong Zhang
Designing a freeform surface to reflect or refract light to achieve a target distribution is a challenging inverse problem. In this paper, we propose an end-to-end optimization str…
Scalable and High-Quality Neural Implicit Representation for 3D Reconstruction
Leyuan Yang, Bailin Deng, Juyong Zhang
Various SDF-based neural implicit surface reconstruction methods have been proposed recently, and have demonstrated remarkable modeling capabilities. However, due to the global nat…
