HUD Controls
The HUD contains the following control: Color.
Concentric Shapes
The Concentric Shapes generator creates a repeating pattern of shapes.
Concentric Shape Circles
Concentric Shape Polygons
Parameters in the Inspector
Shape: Specifies the concentric shapes. There are two choices:
• Circles: Creates concentric circles.
• Polygons: Creates concentric polygons with a minimum of three sides.
Number of Sides: Available when Polygons is selected from the Shape pop-up menu,
determines the number of sides on the polygonal shape. A polygon must have at least
three sides.
Rotation: Available when Polygons is selected from the Shape pop-up menu, determines
the orientation of the polygonal shapes.
Center: Sets the center point of the generator in the Canvas. The left value slider represents
X; the right value slider represents Y. To access individual X and Y controls, click the
disclosure triangle.
Inner Cutoff: Defines a center stopping area for the generator. A value greater than 0
creates a hole in the middle of the generator; the greater the value, the larger the hole.
Objects composited below the generator in the project appear in the cutoff areas.
Outer Cutoff: Defines an outer stopping area for the generator. The lower the value, the
more the outer edges of the generator are cut off. Objects composited below the generator
in the project appear in the cutoff areas.
Color Type: Specifies color type. There are two choices:
• 2 Color: Creates two-color concentric shapes. When 2 Color is chosen from the Color
Type pop-up menu, the Color 1, Color 2, and Contrast parameters become available.
• Gradient: Adds additional gradient parameters to the Inspector: the Gradient editor
and Gradient Handling pop-up menu.
