Very simple ray tracing engine in (almost) pure Python. Depends on NumPy and Matplotlib. Diffuse and specular lighting, simple shadows, reflections, no refraction. Purely sequential algorithm, slow execution.

Resuming an existing Devstack installation on Ubuntu after reboot (assuming you have NOT run unstack.sh). IP addresses are the defaults used by stack.sh. In this example I'm using postgres as the database backend rather than the default mysql.

	sudo ip addr flush dev br-ex
	sudo sysctl -w net.ipv4.ip_forward=1
	sudo ip addr add 172.24.4.225/28 dev br-ex
	sudo ip link set br-ex up
	sudo route add -net 10.0.0.0/24 gw 172.24.4.226
	sudo service rabbitmq-server start
	sudo service postgresql start
	sudo service apache2 start
	export SERVICE_TOKEN=password
	export OS_TENANT_NAME=demo

	### MATPLOTLIBRC FORMAT

	# This is a sample matplotlib configuration file - you can find a copy
	# of it on your system in
	# site-packages/matplotlib/mpl-data/matplotlibrc. If you edit it
	# there, please note that it will be overridden in your next install.
	# If you want to keep a permanent local copy that will not be
	# over-written, place it in HOME/.matplotlib/matplotlibrc (unix/linux
	# like systems) and C:\Documents and Settings\yourname\.matplotlib
	# (win32 systems).
