Tree shading

ARB_NT/Tree/Tree shading...

Allows to select if and how to shade the tree.

First select the shader to use from the selection list. To configure specific setting of the selected shader press 'Configure'.

Generic settings (valid for all shaders) are described in the following sections.

In the 'Active color range' section you can select which color-range to use for the selected shader. The available color-ranges depend on the (current) dimension of the shader (which is displayed below).

In the 'Overlay' section you can define whether to overlay the tree shading with

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.

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.

The settings described above are shader-specific (ie. each shaders remembers these settings and restores them when the shader is selected again).
