Example of daylight simulation with a lightpipe. The lightpipe has a mirror
finish, and extends through several doorways towards the outside above the
window in the far wall. A heliostat was modeled and placed at the pipe
aperture outside. It is aligned towards the sun, reflecting sunlight
directly into the pipe, which is then conveyed through the pipe towards the
viewer. A mirror inclined at 45 degrees (seen from the back) decouples light
from the lightpipe and directs it to the ceiling, illuminating the room
indirectly.

photons and 1000000 caustic photons. Photon ports were
defined for the window, pipe aperture, and the
heliostat.

ambient value.
