Installation

Raytools requires MacOS or Linux operating system with python >=3.7. For windows you can consider using docker (https://www.docker.com/products/docker-desktop/ ). raytools can be installed in the python:3.9 container.

The easiest way to install raytools is with pip:

pip install --upgrade pip
pip install raytools

or if you have cloned this repository:

cd path/to/this/file
pip install .

Note: raytools depends on a small subset of Radiance executables (rcalc, vwrays, getinfo, pvalue). If these are not available in the $PATH at the time of installation, then those precompiled (macos or linux) binaries will be installed to the same bin/ as the current python (and raytools), which could be in a virtualenv. This avoids overriding the existing install of these programs, but it does require that you make sure that the enviroment at installation is the same as when using raytools.

Getting Started

After installation, the raytools executable should be available from the command line. See “raytools –help” and “raytools metric –help” for usage.
