Checkpoint 1

For the first checkpoint of the Ray Tracer I am building for CSCI-711 Global Illumination, here are two pictures of the scene. Picture on the left is the scene from the expected viewpoint, the picture on the right is just the same scene from a different angle.

For the scene I’m using two spheres and a scaled cube as a floor.

The parameters of the scene:

  • Green Sphere
    • Scaled in (x, y, z) -> (0.4,0.4,0.4).
    • Translated in (x, y, z) -> (0,0.1,-2) .
  • Red Sphere
    • Scaled in (x, y, z) -> (0.3,0.3,0.3), smaller than the green on.
    • Translated in (x, y, z) -> (-0.5,-0.2,-2.5), comparing with the green one this one is to the left, below and in the back of the green sphere.
  • Floor
    • Scaled in (x, y, z) -> (3,0.1,6), small on y and large on x and z.
    • Translated in (x, y, z) -> (-0.7,-0.8,-4), below the spheres and moved a bit to the left.
  • Phong illumination model
    • Position (x, y, z) -> (0.5, 2.5, 0.0), essentially above and a little to the right of the camera
    • Intensity (x, y, z) -> (1.0, 1.0, 1.0)
    • Ambient light (x, y, z) -> (0.5, 0.5, 0.5)
  • Camera (left picture)
    • World position (x, y, z) -> (0,0,0)
    • Look at (x, y, z) -> (0.0,0.0,-1.0)
