Gradient Informed Proximal Policy Optimization
Abstract
We introduce a novel policy learning method that integrates analytical gradients from differentiable environments with the Proximal Policy Optimization (PPO) algorithm. To incorporate analytical gradients into the PPO framework, we intr...

Differentiable Hybrid Traffic Simulation
Abstract
We introduce a novel differentiable hybrid traffic simulator, which simulates traffic using a hybrid model of both macroscopic and microscopic models and can be directly integrated into a neural network for traffic control and flow op...

Precise Hausdorff distance computation for freeform surfaces based on computations with osculating toroidal patches
Abstract
We present an efficient algorithm for computing the precise Hausdorff Distance (HD) between two freeform surfaces. The algorithm is based on a hybrid Bounding Volume Hierarchy (BVH), where osculating toroidal patches (stored in the le...

Surface--surface-intersection computation using a bounding volume hierarchy with osculating toroidal patches in the leaf nodes
Abstract
We present an efficient and robust algorithm for computing the intersection curve of two freeform surfaces using a Bounding Volume Hierarchy (BVH), where the leaf nodes contain osculating toroidal patches. The covering of each surface...

Efficient minimum distance computation for solids of revolution
Abstract
We present a highly efficient algorithm for computing the minimum distance between two solids of revolution, each of which is defined by a planar cross-section region and a rotation axis. The boundary profile curve for the cross-sect...
