# modeling-env-mapping-1: Environment Mapping

# Environment Mapping can be used to simulate reflection, using a particular texture
# called a "sphere map".
# You can create such texture from a panorama using e.g. the Polar coordinate
# effect of Gimp.


# Imports and inits Soya (see lesson basic-1.py).

soya.init()
soya.path.append(os.path.join(os.path.dirname(sys.argv[0]), "data"))
