Prerendered Images

In the project's data directory are some prerendered images. These images were generated by using different values for the lighting parameters of the crystal ball and table. In the description below, I use following acronyms:

• cb-refr - Crystal ball refractive index
• cb-refl - Crystal ball reflective factor
• cb-tran - Crystal ball transparency factor
• tb-refl - Table reflective factor

The image files are as follows:

• cb.1.ppm.Z - This is a rendering of the scene with the default values, which are: cb-refr 1.3, cb-refl 0.0, cb-tran 0.6, tb-refl 0.3.

• cb.2.ppm.Z - This scene uses the values of: cb-refr 1.5, cb-refl 0.3, cb-tran 0.6, tb-refl 0.3.

• cb.3.ppm.Z - This scene uses the values of: cb-refr 1.3, cb-refl 0.3, cb-tran 0.4, tb-refl 0.5.
