goray / Home


goray is a raytracer written in Go, based on the Yafaray rendering engine. It is released under the GNU Lesser General Public License v3 and is written by Ross Light.

goray is beta quality software and is not ready for production use. Many features are missing, some things may not work right, and the behavior of the program is not well-documented.
