Well wave type can give you a start:
ramp_wave : goes 0 to 1 linearly. Default for gradient and onion.
triangle_wave : goes from 0 to 1, then back to 0 linearly. Have a
periodicity of 2. Default for wood and marble.
sine_wave : use a sinusoidal curve scaled and shifted to the 0..1 range.
Have a periodicity of 2. Default for wave and ripples.
scallop_wave : Use the absolute value of the sin.
cubic_wave : zero slope at 0 and 1, maximum slope at 0.5 with smooth
poly_wave Value : Use Value as an exponent. If value is >1, it start
with no slope at 0 and increase exponentially toward 1. If Value <1, it
start sharply and the slope diminishes toward 1 (think of the graph of a
square or cubic root). Using Value = 0 should return 1 everywhere.
