Many functions of the SG-Lib are based on analytical geometry and could be parallelized or accelerated via a GPU or external GPU (eGPU) with CUDA interface. CUDA seems to be a product of NVIDA, so that AMD products currently do not seem to be usable for GPU applications with Matlab. However, links are collected here to accelerate solutions for specific challenges such as collision/contact detection, rolling motion or Boolean operations on solid models.
