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

OSPRay internally builds on top of Intel Embree and Intel ISPC (Implicit SPMD
Program Compiler), and fully exploits modern instruction sets like Intel SSE4,
AVX, AVX2, AVX-512 and NEON to achieve high rendering performance, thus a CPU
with support for at least SSE4.1 is required to run OSPRay on x86_64 or a CPU
with support for NEON is required to run OSPRay on ARM64 architectures.
