Stochastic Gradient Estimation for Higher-order Differentiable Rendering
Zican Wang, Michael Fischer, Tobias Ritschel
We derive methods to compute higher order differentials (Hessians and Hessian-vector products) of the rendering operator. Our approach is based on importance sampling of a convolut…

Neural Bounding
Stephanie Wenxin Liu, Michael Fischer, Paul D. Yoo +1
Bounding volumes are an established concept in computer graphics and vision tasks but have seen little change since their early inception. In this work, we study the use of neural…
