Markus Tavenrath is a senior developer technology engineer at NVIDIA, focused on rendering technologies that bring high interactivity to complex scenes. This work includes both GPU and CPU strategies to solve typical scene-graph operations related to rendering. In addition, Markus works on various Vulkan projects, including Vulkan-Hpp, the C++ bindings for Vulkan. Previously, he implemented parts of OptiX, improved SceniX, NVIDIA's scene-graph technology, and developed several ray-tracing demos. He also worked in close cooperation with external partners to improve rendering performance and scene-graph usability. Upon first joining NVIDIA, Markus worked primarily on GPU ray-tracing for SceniX. He finished his studies in computer science with a focus on computer graphics in 2008, and was one of the first using ray-tracing on CUDA for his diploma thesis.
