public class SolidPolygonArrow
extends AbstractCompositeShape

A 3D arrow shape composed of a cylindrical body and a conical tip.

The arrow points from a start point to an end point, with the tip located at the end point. The arrow's appearance (size, color, transparency) can be customized through the constructor parameters.

Usage example:

// Create a red arrow pointing from origin to (100, -50, 200)
SolidPolygonArrow arrow = new SolidPolygonArrow(
    new Point3D(0, 0, 0),      // start point
    new Point3D(100, -50, 200), // end point
    8,                         // body radius
    20,                        // tip radius
    40,                        // tip length
    16,                        // segments
    Color.RED                  // color
);
shapeCollection.addShape(arrow);

// Create a semi-transparent blue arrow
SolidPolygonArrow seeThroughArrow = new SolidPolygonArrow(
    new Point3D(0, 100, 0),
    new Point3D(0, -100, 0),
    10, 25, 50, 12,
    new Color(0, 0, 255, 128)  // blue with 50% transparency
);

Constructor Details

SolidPolygonArrow

public SolidPolygonArrow(Point3D startPoint,
 Point3D endPoint,
 double bodyRadius,
 Color color)

Constructs a 3D arrow pointing from start to end with sensible defaults.

This simplified constructor automatically calculates the tip radius as 2.5 times the body radius, the tip length as 5 times the body radius, and uses 12 segments for smoothness. For custom tip dimensions or segment count, use the full constructor.

Parameters:

startPoint - the origin point of the arrow (where the body starts)

endPoint - the destination point of the arrow (where the tip points to)

bodyRadius - the radius of the cylindrical body; tip dimensions are calculated automatically from this value

color - the fill color (RGBA; alpha controls transparency)
