Prism

Date: 2005/06/21
Resolution: 500 x 500
Objects/Polygons: 8 / 15
Rays Per Pixel: 10000
Max Path Length: 10 jumps

Scene: Box with dispersive prism
Details: A room with dispersive prism refracting a light source. The light is a rectangle at the center of the far end of the room. The bottom of the image shows a slice through the middle of the image split into the three colour components. The effect of dispersion can be easily seen by the shift of parts of the image.

Water

Date: 2005/06/19
Resolution: 400 x 400
Objects/Polygons: 10 / 19
Rays Per Pixel: ?
Max Path Length: 10 jumps

Scene: Cornell box with (fake) water
Details: Cornell box with a thin bumpmapped box giving a fake water-like effect.

Chromatic Aberration

Date: 2005/06/15
Resolution: 400 x 400
Objects/Polygons: 9 / 7
Rays Per Pixel: 5000
Max Path Length: 10 jumps

Scene: Diamond sphere from Cornell box
Details: Images showing chromatic aberration from the sphere. A different refractive index is given for the red, green and blue components of a particular object. When a coloured photon hits the object it is split into the three components and each traced separately. The refractive indices in this exaggerated case are 2.42, 2.32 and 2.22.
