Detailed Description

Interface for an Arc Model instance.

An arc with the following geometric parameters:

Start Angle: Change which part of the ellipse is used to draw the arc
End Angle: Change which part of the ellipse is used to draw the arc
Position: Change the position of the arc's origin
Dimensions: Change the dimensions of the ellipse used to draw the arc
Max Angle Segment: Affects the number of vertices used by changing the angular difference between vertices along the arc. If you want to use X vertices to draw the arc, then set Max Angle Segment equal to PI / X

An arc with the following geometric parameters:

Line Width: Change the width of all of the arc's line segments
Line Color: Change the color of all of the arc's line segments
Line Stipple Pattern: Change the stipple pattern of all of the arc's line segments

Special Considerations:

In a 2D plane, the positive Y-Axis is 0 radians with clockwise being the positive direction
If the start and end angle are 0 and 2 * PI respectively, an ellipse is drawn
If the height of the arc is 0, a line is drawn

virtual

Set the position of a vertex in the arc When vtx is 0,.

The passed in vertex becomes the origin of the arc

When vtx is 1,

The passed in vertex becomes the end vertex of the arc

The origin of the arc is updated to be the midpoint between the start/end vertices
The x-dimension is set to be the distance between the start and end vertices

When vtx is 2,

The passed in vertex is used to infer the height of the arc via calculateHeight()
NOTE: This call requires a setPosition(1, [SomeVertex]) call first to define the arc 'normal'
