Global Illumination

• For Linux/Mac OS users:

  • Make sure you have g++ compiler installed
  • Open your terminal.
  • cd to source/SimplePT
  • Type: make
  • In the same folder. You will get a binary file naned "a.out"
  • Type: ./a.out 20 (It means take 20 samples for each sub-pixel)
  • Wait some minutes, until the image is 100% rendered
  • There will be an image.ppm file. You can open it.

• For Windows Users:

  • Open the solution in Visual Studio
  • Set to Release build mode. Then build it.
  • Run it.
  • You can get a result( image.ppm ), but you might not be able to open it.
  • There is an online image converter here: http://www.sciweavers.org/free-online-image-converter
  • Convert the .ppm file, then you can see the image.

Have fun!

This is a screenshot of the rendering result:
