ray

Rhino package · v0.1.1 · updated 11/11/2026

New

ray: GPU/CPU ray engine for single-ray environmental analyses in Grasshopper (incident radiation, direct sun hours, sky view, view factors, sky matrix). Python3 Script components backed by the bundled native ray_engine module (Embree on CPU); no Python packages are downloaded. Windows x64: OptiX on NVIDIA GPUs (Turing or newer), Embree CPU fallback. macOS 13+ on Apple Silicon: CPU (Embree). New in 0.1.1: study nodes output plain points and numbers by default, a drop-in for the LBT node; set the new compact_ input to True for a compact results object on very large meshes. Ray Deconstruct Results now needs compact_ True; Ray Result Stats also takes plain numbers. OptiX on NVIDIA GPUs, else Embree on the CPU. Most components take Ladybug Tools inputs (sky matrix, sun vectors, location); Ray Sky Matrix covers EPW-only use. Free to use under the Ray Freeware Licence (LICENSE.txt in the package); contact pablo@klimatica.tech.
