| 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. |

Parameters
| Name | Type | Description |
|---|---|---|
| angle | Float | No description |
| base_noise_amp | Float | No description |
| elevation | Float | No description |
| k_smoothing | Float | No description |
| 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). |
| Octaves | Integer | The number of octaves for fractal noise generation. More octaves add finer details to the terrain. |
| 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. |
| rugosity | Float | No description |
| 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. |
