Abstract:
1. A method of forming a computer generated image that includes characteristic information of pixels, wherein the characteristic information of at least a portion of the pixels is determined at least in part by sampling noise data defined by a scene including a three-dimensional model of an object, the method comprising: creating first noise data using a processor; constraining the first noise data using a processor such that the first noise data has a frequency spectrum contained substantially between first and second frequency values; wherein a sum of the frequency spectrum of the first noise data and a copy of the frequency spectrum of the first noise data is substantially flat, wherein the copy of the frequency spectrum is translated in frequency by the difference between the first and second frequency values wherein the frequency spectrum of the first noise data diminishes abruptly outside of a range between the first and second frequency values, wherein the frequency spectrum of the first noise data diminishes from a significant magnitude to approximately zero within a power of two from the first and second frequency values.
