%description
Intel OSPRay is an open source, scalable, and portable ray tracing engine for
high-performance, high-fidelity visualization on Intel CPUs, Intel Xe GPUs,
and Aarch64/ARM64 CPUs.

The purpose of OSPRay is to provide an open, powerful, and easy-to-use
rendering library that allows one to easily build applications that use ray 
tracing based rendering for interactive applications (including both surface-
and volume-based visualizations). OSPRay runs on anything from laptops, to 
workstations, to compute nodes in HPC systems.
