In the 'Value phasing' section you can modify the way how values are mapped to colors.
This can be useful whenever the tree is shaded continuously, e.g. whenever any topology-related values are vizualized.
Basically this allows to modify mapping-frequency and -offsets.
The frequency scaler defines how often the color-range is mapped to the value-range:
the default frequency is 1.
a frequency of 2 means: the first half of the value-range is displayed in the same colors as the second half.
a frequency of 0.5 means: the value-range is only mapped to the first half of the color-range.
The two offset scalers (pre- and post-shift) define linear offsets applied during mapping:
the default values for both are zero.
pre-shift operates on values and
post-shift operates on colors.
As long as frequency is 1, they behave quiet similar. For other frequencies they act differently: one shifts local, the other global.
The 'Alternate?' toggle defines how to repeat color-ranges (this only applies if frequency is greater 1!). If checked, each 2nd repeated color-range will be mapped in reverse order.
Example: If the used color-range contains continuous colors from red to green, and 'Alternate?' is checked, the color will fade from red to green and back to red (if unchecked it would fade from red to green, then jump back to red and again fade to green).
If you select a cyclic color-range (eg. the 'Rainbow' range) you might want to try frequencies > 1 without checking 'Alternate?'.
