RT

Eye (Camera Position)

• Object <eye>
• Restrictions : Only one eye is defined
• Parameters
  • [position] X Y Z (pixels)
  • [rotation] X Y Z (in degrees)

Lights Sources

• Object <light>
• Parameters:
  • [position] X Y Z (pixels)
  • [rotation] X Y Z (in degrees) -> if not (0,0,0), defines parallel light source
  • [color] 0xABCDEF : Color of specular lighting

Scene Parameters

• Object <scene>
• All global scene parameters are set here
• Parameters

Object types

• Available objects <sphere> <plane> <cylinder> <cone> <paraboloid> <disc>
• Parameters:
  • [position] X Y Z (pixels)
  • [rotation] X Y Z (in vector direction)
  • [color] 0xABCDEF (Hexadecimal)
  • [size] in pixels except for <paraboloid> and <cone> in degrees. For disc, if < 0 : Plane with hole
  • [Spec/Diff/Amb] Phong coefficients (must all be between 0 and 1):
    • Specular
    • Diffuse
    • Ambient
  • [R/T/Rf] Descartes coefficients:
    • Reflection (0 : No reflection at all. 1 : Fully reflective. Must be between 0 and 1)
    • Transparency (0 : Fully opaque. 1 : Fully transparent. Must be between 0 and 1)
    • Refraction (1 : No ray refraction. Must be between 1 and 2)
  • [perturbation] See below
  • [texture] See below

Cutters

• All objects can be cut. Cutter type is <plane> by default.
• By default, Phong and Descartes coefficients are the same as cut object.
• Only non transparent objects are cut (T = 0)
