Inputs

|---|---|---|
| control | VirtualArray | Global control heightmap that defines the overall shape of the output. |
| dx | VirtualArray | Displacement with respect to the domain size (x-direction). |
| dy | VirtualArray | Displacement with respect to the domain size (y-direction). |
| envelope | VirtualArray | Heightmap used as a post-process amplitude multiplier for the generated noise. |

| out | VirtualArray | TODO |
Parameters
| Name | Type | Description |
|---|---|---|
| displacement | Float | Maximum displacement of segments. |
| eps | Float | Used to bias the area where points are generated in cells. |
| Spatial Frequency | Wavenumber | Base spatial frequencies in the X and Y directions. The frequencies are defined with respect to the entire domain: for example, kw = 2 produces two full oscillations across the domain width (and similarly for the Y direction). |
| noise_amplitude_proportion | Float | Proportion of the amplitude of the control function as noise. |
| 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. |
| primitives_resolution_steps | Integer | Additional resolution steps in the primitive resolution. |
| resolution | Integer | Number of resolutions in the noise function. |
| Seed | Random seed number | Random seed number. The random seed is an offset to the randomized process. A different seed will produce a new result. |
| slope_power | Float | Additional parameter to control the variation of slope on terrains. |
| subsampling | Integer | Function evaluation subsampling, use higher values for faster computation at the cost of a coarser resolution. |
