pigment / normal attributes

Nom

Exemple

frequency
// oscillation freq. of radial, ripples, waves, etc
lambda
// change surface perturbation property
// makes turbulence more "swirly"
turbulence
// Takes a float or vector, see also octaves, //omega, lambda, frequency

octaves
// increases the "folds" in turbulence changes
omega
// change surface perturbation property
// makes turbulence more "krinkly"
phase
// change the phase of ripples, etc.
// Animation note:
// As phase DECREASES,
// ripples move OUTWARD.

frequency 2.0



lambda 1.2
// (1.0...5.0) [2.0]

turbulence <0, 1, 0.5>

// how much to turbulate the texture

//(0...1 or more)
octaves 3

// (1...10) [default is 6]
omega 1.2

// (0.0...2.0) [default is 0.5]

phase 0.5
