报告摘要：

Designing a freeform surface that reflects or refracts light to achieve a target distribution is a challenging inverse problem. In this talk, I will present two recent works on optimizing freeform lenses represented as triangle meshes to create desired caustic patterns. The first work introduces a differentiable rendering model that calculates caustics from a mesh surface without the need for sampling. This model enables direct optimization based on the difference between the target and resulting caustic images, leading to single-sided freeform lens designs with caustics closely matching the target. In the second work, we propose a technique that simultaneously optimizes both sides of a freeform lens, using a bijective correspondence between the two sides to control light refraction paths. Our preliminary results are promising, suggesting new possibilities for freeform optics design.
