Inputs
| Name | Type | Description |
|---|---|---|
| dr | VirtualArray | Displacement relative to the domain size (radial direction). |
| input | VirtualArray | The input heightmap. |
Outputs
| Name | Type | Description |
|---|---|---|
| output | VirtualArray | The filtered heightmap result. |
Parameters
| Name | Type | Description |
|---|---|---|
| Distance Function: | Enumeration | Determines the method used for distance calculation. Options: Chebyshev, Euclidean, Euclidean/Chebyshev, Manhattan. |
| 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. |
| Mix Factor | Float | Mixing factor for blending input and output values. A value of 0 uses only the input, 1 uses only the output, and intermediate values perform a linear interpolation. |
| Mix Method | Enumeration | Method used to combine input and output values. Options include linear interpolation (default), min, max, smooth min, smooth max, add, and subtract. |
| 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. |
| Falloff Exponent | Float | Controls the shape power law. |
