The Curse of Prince Lambert
Frequently Asked Questions and Problem Clarifications
| Q. What should I do if my software does not support tm25? A. Please contact your vendor and ask them to contact the illumination guild (illuminationguild@iodc.org). The guild will work with the vendor to provide a file that you can use. |
| Q. Why do the Duke Radiance files use exiting rays that vary from 500 to 700 nm? A. The story uses blue rays, but wavelength does not matter for solving the problem. In the text files, wavelength was incremented by 0.01 for each ray (e.g., 500.01, 500.02, 500.03, … 700.00). That was done so that you can compare the wavelength of the rays to verify that you are comparing the same ray from the two files. |
| Q. Problem statement says “As a wizard, you can cut and polish and assemble to sub nanometer precision, with perfect optical surfaces.” Does this mean planar cuts only, or can we grind and polish curved surfaces? A. Polished curved surfaces are allowed. |
| Q. Could you provide a summary of the problem that does not use Old-English? A. Please download ‘TheCurseOfPrinceLambert_V5.pdf. |
Q. Can the deadline be extended to May 1st?
