Filled Generators

The filled generators create a filled shape on the terrain heightmap.
The filled generators can be used as a starting terrain heightmap shape, or saved as a terrain heightmap file and used in conjunction with many modifiers that utilize external heightmap or mask or weightmap files.

Common Features

The filled generator dialogs maintain the last control settings for the current session. This allows for a quick repeat of the last settings.

OK button: accept the dialog settings.
Cancel button: cancel the dialog.
Random button: randomize all of the dialog values


Filled Circle
Generates a filled circle shape.

Filled Circle Generator

Center X: the filled circle center X coordinate.
Center Y: the filled circle center Y coordinate.
Radius: the filled circle radius.
Circle value: the altitude value of the filled circle region.
Outside value: the altitude value of the area outside of the filled circle.
Fill outside: whether to fill the outside area with the outside value.


Filled Quadrilateral
Generates a filled quadrilateral shape of four sides.

Filled Quadrilateral Generator

X0,Y0: a quadrilateral corner coordinate pair.
X1,Y1: a quadrilateral corner coordinate pair.
X2,Y2: a quadrilateral corner coordinate pair.
X3,Y3: a quadrilateral corner coordinate pair.
Quad value: the altitude value of the filled quadrilateral region.
Outside value: the altitude value of the area outside of the filled quad.
Fill outside: whether to fill the outside area with the outside value.


Filled Rectangle
Generates a filled rectangle shape

Filled Rectangle Generator

X offset: the filled rectangle top-left X coordinate.
Y offset: the filled rectangle top-left Y coordinate.
Width: the filled rectangle width.
Length: the filled rectangle length.
Rect value: the altitude value of the filled rectangle region.
Outside value: the altitude value of the area outside of the filled rectangle.
Fill outside: whether to fill the outside area with the outside value.


Filled Square
Generates a filled square shape

Filled Square Generator

X offset: the filled square top-left X coordinate.
Y offset: the filled square top-left Y coordinate.
Size: the filled square size (width and length).
Square value: the altitude value of the filled square region.
Outside value: the altitude value of the area outside of the filled square.

Filled Triangle
Generates a filled triangle shape.
Two styles of triangle generation are provided, an isosceles triangle and a trigon specified by three coordinate pairs.

Filled Triangle Generator

Style: whether to create an isosceles or coordinate trigon filled shape.

Direction: the pointing direction of the isosceles triangle.
X offset: the isosceles triangle bounding box X offset coordinate.
Y offset: the isosceles triangle bounding box Y offset coordinate.
Width: the isosceles triangle bounding box width.
Length: the isosceles triangle bounding box length.

X0,Y0: a trigon corner coordinate pair.
X1,Y1: a trigon corner coordinate pair.
X2,Y2: a trigon corner coordinate pair.

Triangle value: the altitude value of the filled triangle region.
Outside value: the altitude value of the area outside of the filled triangle.
Fill outside: whether to fill the outside area with the outside value.
