Back in 2016, I wrote about the potential to use partial evaluation, a technique from the world of compilers, to optimize the rendering of SDFs. Using compiler techniques is appealing because SDFs render 3D scenes as code. Matt Keeter had commented at the time to share that interval arithmetic can be used to achieve this purpose. However, the downside is that to make this work, you have to implement a whole compiler for your SDFs. There are also potentially simpler techniques, such as using bounding volumes to determine which objects in the world can intersect with your view frustum and avoid evaluating an SDF corresponding to the entire scene. Still, even if you can constrain the number of objects being sampled, SDFs can still remain expensive to render.

何淇丹说“大厂有些安全性、隐私性还有法律风险方面的顾虑，总是会担心各方都不能接受，只能让大模型放到一个很受限的场景里面去用。但是彼得自己做给自己用的，他就觉得为啥不能尝试？就给你所有的权限，看看大模型到底能做到什么程度。结果意外证明了，这个思路跑得通，大家其实能认可”。
