Extractors

The mask extractor devices extract mask weightmap data.
This weightmap data is typically used in terrain layers and splatmaps.


Altitude Extractor
Creates a mask that is between the low and high altitudes.

Altitude Extractor

Low – the low altitude value.
High – the high altitude value.
Falloff – a falloff of greater than 0 provides a gradient inclusion of the altitudes lower than Low and higher than High. For example, a properties selection of Low=40, High=60, Falloff=20, results in a mask that contains values between altitudes of 20 (40-20) and 80 (60+20). The datamap altitudes that are between 40 and 60 will be white (255) in the mask, and the datamap altitudes between 20 to 40, and 60 to 80, will be gradient mask values from black to white, and white to black.
Invert – invert the mask.


Concavity Extractor
Creates a mask that is the concave (lower indented) regions of the datamap.

Concavity Extractor

Detail – the concavity detail radius, 0 is none, 1 is small detail, 256 is large detail.
Strength – the amount of concavity depth to show on the mask.
Invert – invert the mask.


Convexity Extractor
Creates a mask that is the convex (higher bump) regions of the datamap.

Convexity Extractor

Detail – the convexity detail radius, 0 is none, 1 is small detail, 256 is large detail.
Strength – the amount of convexity depth to show on the mask.
Invert – invert the mask.


Direction Extractor
Creates a mask that is the surfaces of the datamap that are facing the specified direction.

Direction Extractor

Direction – the compass direction, with North up and South down.
Flat – exclude the flatter regions.
Falloff – include a percentage of the two surrounding directions.
Invert – invert the mask.


Flowline Extractor
Creates a mask that is the water flow through the heightmap valleys.

Flowline Extractor

Slope Minimum – the minimum terrain slope used to determine a valley.
Slope Maximum – the maximum terrain slope to determine a valley.
Invert – invert the mask.
Normalize – normalize the mask.


High Frequency Extractor
Creates a mask that contains the high frequency data in the datamap.

High Frequency Extractor

Detail – the high frequency detail radius, 0 is none, 1 is small detail, 50 is large detail.
Strength – the amount of high frequency data to show on the mask.
Invert – invert the mask.


Low Frequency Extractor
Creates a mask that contains the low frequency data in the datamap.

Low Frequency Extractor

Detail – the low frequency detail radius, 0 is none, 1 is small detail, 50 is large detail.
Strength – the amount of low frequency data to show on the mask.
Invert – invert the mask.


Slope Extractor
Creates a mask that contains the data between two slope limits.

Slope Extractor

Minimum – the minimum terrain slope in degrees.
Maximum – the maximum terrain slope in degrees.
Falloff – a falloff of greater than 0 provides a gradient inclusion of the slopes lower than Minimum and higher than Maximum. For example, a properties selection of Min=30, High=60, Falloff=10, results in a mask that contains values between slope degrees of 20 (30-10) and 70 (60+10). The datamap slopes that are between 30 and 60 will be white (255) in the mask, and the datamap slopes between 20 to 30, and 60 to 70, will be gradient mask values from black to white, and white to black.
Invert – invert the mask.


Steepness Extractor
Creates a mask that is the steep slopes of the terrain.

Steepness Extractor

Brightness – adjust the brightness of the mask.
Contrast – adjust the contrast of the mask.
Intensity – adjust the intensity of the mask.
Invert – invert the mask.


Uphill Extractor
Creates a mask that is the uphill valleys of the terrain.

Uphill Extractor

Brightness – adjust the brightness of the mask.
Contrast – adjust the contrast of the mask.
Intensity – adjust the intensity of the mask.
Invert – invert the mask.
