Caldera Node

Caldera generates a volcanic caldera landscape.

Inputs

Name	Type	Description
dr	VirtualArray	Displacement with respect to the domain size (normal direction).

Outputs

Name	Type	Description
output	VirtualArray	Caldera heightmap.

Parameters

Name	Type	Description
center	Vec2Float	Reference center within the heightmap.
noise_r_amp	Float	Noise amplitude for the radial displacement.
noise_ratio_z	Float	Noise amplitude for the vertical displacement.
Gain	Float	Mid-centered gain transformation applied to the elevation values. This is a non-linear recurve operator centered around the mid elevation (typically 0.5). Increasing the gain pushes values toward the minimum and maximum elevations, creating flatter low/high regions with a steeper transition around the midpoint.
Gamma	Float	Standard gamma correction applied to the elevation values. This is a monotonic power-law remapping that shifts emphasis toward low or high elevations, making the overall shape sharper or bulkier without changing its ordering.
Invert Output	Bool	Inverts the output values after processing, flipping low and high values across the midrange.
Remap Range	Value range	Linearly remaps the output values to a specified target range (default is [0, 1]).
Saturation Range	Value range	Modifies the amplitude of elevations by first clamping them to a given interval and then scaling them so that the restricted interval matches the original input range. This enhances contrast in elevation variations while maintaining overall structure.
Smoothing Radius	Float	Defines the radius for post-processing smoothing, determining the size of the neighborhood used to average local values and reduce high-frequency detail. A radius of 0 disables smoothing.
radius	Float	Crater radius.
sigma_inner	Float	Crater inner lip half-width.
sigma_outer	Float	Crater outer lip half-width.
z_bottom	Float	Crater bottom elevation.
