The Ellipse component generates an ellipse or a circle. The colors of the ellipse and the background can be customized using the Color and Background parameters. This is a map component, it can be located in the Patterns category on the Components Bar. This component can output HDR colors. You cannot freely control the ellipse coordinates because this component is seamless. A similar non-seamless component with unrestricted coordinates, Free Ellipse, can be used instead.
Defines the ellipse color. This input can accept HDR colors. Color is a so-called 'seamlessizer input' – it can safely accept connections from non-seamless components without preventing the resulting filter from generating seamlessly-tiled results.
Defines the background color. This input can accept HDR colors.
Radius: Map Input
Defines the length of the ellipse's semimajor axis. Since Radius is a map input, its value can be controlled separately for different image areas by connecting a map component.
Rotation: Map Input
Specifies the angle of rotation in degrees. Since Rotation is a map input, its value can be controlled separately for different image areas by connecting a map component.
Squash: Map Input
Specifies how the ellipse is squashed, i.e. the non-uniformity of flattening along the axes. The value of 0 corresponds to the circle, while negative values squash the ellipse horizontally, and positive values squash it vertically. Since Squash is a map input, its value can be controlled separately for different image areas by connecting a map component to this input.
Bevel Width: Map Input
Defines the width of the ellipse bevel. The less the bevel width, the sharper the ellipse edges. When Bevel Width is zero, the transition zone between Color and Background disappears completely. When Bevel Width is 100, it fills the entire ellipse area. Since Bevel Width is a map input, its value can be controlled separately for different image areas by connecting a map component to this input.
Bevel: Curve Input
Defines the bevel profile of the ellipse (the transition between Color and Background). When Bevel Width is zero, this parameter has no effect. Three predefined bevel profiles are available: Linear, Smooth, and Contours. To customize the bevel profile, connect a curve component to this input.
For best results, the curve connected to the Bevel input should start at 0 and end at 100% – curves like Linear, Step, Gain and Stairs are perfect choices, while curves like Noise or Wave will require additional adjustments or modifications (for example, you can use the Fade component to force the start and end of any curve into desired positions).
