Star Layer¶

About Star Layers¶

A Star Layer is a geometric object that is made by the filling the region resulting from connecting the points of two concentric circles with straight lines. The number of points on which the circles are divided defines the number of peaks of the star. The points over the circles are spread regularly over both circles but one of them has the points rotated N/360/2 degrees from the other circle (being N the number of peaks or points).

Parameters of Star Layers¶

The parameters of the star layers are:

Name	Value	Type
Z Depth Parameter	0.000000	real
Opacity	1.000000	real
Blend Method	Composite	integer
Color		color
Origin	0.500000u,0.000000u	vector
Inver Parameter		bool
Antialiasing		bool
Feather	0.500000u	real
Type of Feather	Fast Gaussian Blur	integer
Winding Style	Non Zero	integer
Outer Radius	1.500000u	real
Inner Radius	0.500000u	real
Angle	0.00	angle
Points	5	integer
Regular Polygon		bool

The parameters of the star layers are the same as the majority of the shape-like objects but it has specific parameters for its own properties.

Outer Radius¶

Defines the radius of the circle where the peaks of the star lay.

Inner Radius¶

Defines the radius of the circle where the valleys of the star lay.

Angle¶

Is the rotation angle for the first peak of the star. Its default value is 90 degrees.

Points¶

Defines the number of divisions done in the circles and therefore the number of points and peaks in the star.

Playing Around¶

Crazy Radii¶

The Outer Radius shouldn’t be greater than Inner Radius. It only changes the star’s orientation:

Inner Radius = 40; Outer Radius = 60	Inner Radius = 60; Outer Radius = 40

You can also play with negative values:

Inner Radius = -40; Outer Radius = 60	Inner Radius = 40; Outer Radius = -60

Winding Style Hacks¶

You can even play with the |Winding_Style_Parameter| and negative values to obtain some effects:

Inner Radius = 40; Outer Radius = -60; WS=even/odd	Inner Radius = -40; Outer Radius = 60; WS=even/odd

Regular 2N-sided Polygons¶

Also you can Linking both radii to create a 2*N sided regular Polygon Layer, where N is the number of points (3 points for this case (six sides)):
