Flowchart depicting rendering algorithm. A) Texel frequency distribution, with “Central Pitch” (4.5 cycles/mm $\approx 6.5$ dB) and “Irregularity” (0.1 cycles/mm $=$  $-$10 dB) parameters indicated. B) First texel with stochastically drawn frequency using a 1-mm texel length. Note that the starting phase of oscillation of the first texel is chosen randomly. C) Nine additional texels with stochastically drawn frequencies. Note that the phase of oscillation is continuous between the borders between adjacent texels. Adapted from a figure in Burns et al.
