+Intel® Embree is a collection of high-performance ray tracing kernels, developed at Intel. The target users of Intel® Embree are graphics application
+engineers who want to improve the performance of their photo-realistic rendering application by leveraging Embree's performance-optimized ray tracing
+kernels. The kernels are optimized for the latest Intel® processors with support for SSE, AVX, AVX2, and AVX-512 instructions. Intel® Embree supports
+runtime code selection to choose the traversal and build algorithms that best matches the instruction set of your CPU. We recommend using Intel®
+Embree through its API to get the highest benefit from future improvements.
