Usage: raytracer2 [-uSch] [--cluster="ip"] [--res=width,height] [--ssaa=nb] [--soft=nb]
       		  [--fov=nb] [--dof=nb] [--tesla=nb] [--depth=nb] [--stereo] scene_file

Renders the scene for the provided scene_file.

  -u
	Live updates the rendered part of the image as the laoding progresses.
  -S
	Enables stereoscopic anaglyph 3D rendering. This flag may disable some effects such as depth of field or anti-aliasing.
  -c
	Enable cluster mode as the master server, clients can then connect and start computing parts of the image
  -h
	Displays this help message

  --cluster="ip"
	ip: an ip address (i.e.: 192.168.1.11)
	Enable cluster mode as a client and tries to connect to the specified ip address

  --res=width,height
	Sets the resolution of the rendered image to the one specified

  --ssaa=nb
	Enables SSAA (SuperSampled Anti-Aliasing) with the specified resolution multiplier

  --soft=nb
	Enables soft shadows with the specified number of samples per shadow computation

  --fov=nb
	Sets the fov to the specified value

  --dof=nb
	Enables depth-of-field with the specified number of samples per pixel

  --tesla=nb
	Generates an image with the specified value as the size of the rendered pixels.
	The image is then re-rendered at a higher level of detail, until the tesselation level equals 1.

  --depth=nb
	Sets the limit for how much reflection and refraction can a single ray perform to the specified value.

  --stereo
	The effect is the same as the "-S" flag. Enables stereoscopic anaglyph 3D rendering.
