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.

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.

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

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

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.

Fill outside: whether to fill the outside area with the outside value.

**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.

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.
