The BIM HVACTool supports OSPray from Intel as an additional rendering engine. The goal with the new rendering engine is to blend realistic VR representations with simulation results.
OSPray is an open-source, scalable, and portable ray tracing engine developed by Intel that can generate high-quality visualizations of complex 3D scenes. It can be used for a variety of applications, including rendering photorealistic images and visualizing large-scale scientific data sets. OSPray is designed to be highly parallel and optimized for modern CPUs, making it well-suited for use on clusters and supercomputers.
