• Here is a link to how to do it on the different platforms https://wiki.libsdl.org/Installation
• This program should be run on a linux OS, we didn't try on others one, feel free to try and give feedback :)

• Usage using command line:

  • Go in the "build" directory
  • run "cmake .."
  • run "make"
  • run the program ( options are written below )

• Program options :

  • You need at least the -n option with another option such as -i for the input file or -r to randomly generate items
  • Format : ./bin/synthese_image -n [level to load] -i [input file] -o [output file] -r [number of elements] -s[value]
  • -n [value] : level to load
  • -i [input file] : The input file contains the scene that you want to load
  • -o [output file]: The output file is the name of the file for ppme format export
  • -r [value]: The number of elements is the number of elements you want to randomly generate
    • If the -r option is active , the input file wont be red
  • If the level number is superior to 2 , the output file wont be created
  • The levels 1 & 2 require an output file
  • -s [value] : AA(Anti aliasing) value can be 0 (default), 2, 4, 8, 16 no other values
  • -h : show this usage

For a material :

• material name coefRelfection transparence indiceRefraction brillance
  • Example : material wood 100 50 100 0 For the camera :
• camera depth position orientation
  • Exemple : camera 50 (-5 0 0) (1 0 0) For any other object :
• type position rotation scale color angle material
  • Example : sphere (3 -3 3) (0 0 1) (1.0 1.0 1.0) (255 0 0) 0 wood

• Program commands once launched (All have been done with a QWERTY keyboard, some controls can feel weird on an AZERTY layout):
  • Camera movement :
    • E : Move FORWARD
    • D : Move BACKWARD
    • S : Move LEFT
    • F : Move RIGHT
    • Q : Move UP
    • A : Move DOWN
  • Camera rotation :
    • W : Rotate LEFT
    • R : Rotate RIGHT
    • T : Rotate UP
    • G : Rotate DOWN

Here are some examples :

• ./bin/Synthese_Image -n 3 -r 100 -s 4
  • This will create 100 random items in the scene, with AA set to 4
• ./bin/Synthese_Image -n 2 -i myFile -o anotherFile.ppm
  • This will read the file, generate the objects and export the file to ppm format.
