BasicExample

Rnders an image with some predefined settings.

MengerSpongeExample

Renders a menger sponge (like in the picture above). The program is executed using command line and has the following options:

 -i, --iterations    (Default: 3) Number of iterations in range [1, 6]
 -s, --samples       (Default: 300) Number of render samples
 -r, --resolution    (Default: 500) Resolution of rendered image
 -p, --path          (Default: image.png) Path where rendered image will be saved
 -l, --light         (Default: false) Add a light in the middle of the sponge
 -c, --color         (Default: Cyan) White, Gray, Black, Cyan, Yellow, Red, Green, Blue
 -d, --denoiser      (Default: false) Use median filter to reduce noise
 --help              Display the help screen.
 --version           Display version information.
