description         collection of high-performance ray tracing kernels
long_description    Embree is a ${description}, developed at Intel. It \
                    contains algorithms optimized for incoherent \
                    workloads (e.g. Monte Carlo ray tracing \
                    algorithms) and coherent workloads (e.g. primary \
                    visibility and hard shadow rays). It also supports \
                    dynamic scenes by implementing high-performance \
                    two-level spatial index structure construction \
                    algorithms.
