Detailed Description

vrvGraphics implementation of an overlay spider web

A spider web is defined by: 1) An origin vertex, 2) a radius, 3) the number of spokes, and 4) the number of rings

The drawn spider web has the following geometric parameters:

Number of Spokes: Change the number of spokes the spider web has
Number of Rings: Change the rings the spider web has
Position: Change the position of the spider web's origin
Radius: Change the radius of the circle used to draw the spider web
Max Angle Segment: Affects the number of vertices used to draw each ring of the spider web. If you want to use X vertices to draw each ring of the spider web, then Max Angle Segment is equal to (2*PI) / X.
Scale: Change the numeric factor that the spider web is scaled by

The drawn spider web has the following style properties:

Line Color
Line Stipple Pattern
Line Width
Number of Spokes
Number of Rings

Special Considerations:

The spokes and rings will be drawn equally distanced from each other
The spokes indicate the number of diameter length spokes, i.e. there will be 2 times the number of radius length spokes.
