• Zoom: Use two fingers on a touchscreen or the wheel on your mouse
• Reset: Press number 5 to reset both the camera position and the object rotation.

Notes:

A ray set is a collection of rays each characterized by their position, direction and the amount of flux they transport. They are usually traced by an optical simulation software that propagates light rays from a light source through a catadioptric system. They represent the complete distribution of light that such an optical system emits and can be used as a substitute for this complex light source.

This viewer aims at visualizing the distribution of millions of rays written in several formats: the IES-TM-25 file format (.TM25RAYS), the ASCII format with a single header line (.TXT), the SPEOS ray format (.RAY) and the Ray Jack One format (.RJ1DIS). If you wish to visualize such a dataset, please open your own or pick one from the

OSRAM catalog of light sources

. The viewer also computes and shows the resulting intensity distribution which you would usually get as an IES or LDT file from the light source manufacturer.
