DescriptionEfforts from CompBioMed are directed towards creating a virtual human – a personalized digital representation of a human’s biophysical processes. Part of this is HemeLB, a highly scalable, 3D fluid dynamics code that is developing high-resolution simulations of blood flow throughout human-scale vasculature.
Visualizing the results is a significant challenge, particularly due to the complexity and volume of the data. We use Intel OSPRay Studio for visualizing the resulting data directly on the production machine – LRZ’s supercomputer SuperMUC-NG - and producing outputs from 2D to Virtual Reality. We have created a custom plugin to map the data to the highly memory-efficient VDB volumes of Intel Open VKL for delivering visualization at native resolution and interactive frame rates, eliminating data pre-processing. In our exploratory video, we outline our approach that allows the full domain simulated by HemeLB to be visualized at a glance, a challenging task with existing techniques.
