public class WireframeArrow
extends AbstractCompositeShape

A 3D wireframe 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 wireframe consists of:

• Body: Two circular rings connected by lines between corresponding vertices
• Tip: A circular ring at the cone base with lines to the apex

Usage example:

// Create a red arrow pointing from origin to (100, -50, 200)
LineAppearance appearance = new LineAppearance(2, Color.RED);
WireframeArrow arrow = new WireframeArrow(
    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
    appearance
);
shapeCollection.addShape(arrow);

Constructor Details

WireframeArrow

public WireframeArrow(Point3D startPoint,
 Point3D endPoint,
 double bodyRadius,
 LineAppearance appearance)

Constructs a 3D wireframe 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

appearance - the line appearance (color, width) used for all lines

WireframeArrow

public WireframeArrow(Point3D startPoint,
 Point3D endPoint,
 double bodyRadius,
 double tipRadius,
 double tipLength,
 int segments,
 LineAppearance appearance)

Constructs a 3D wireframe arrow pointing from start to end with full control over all dimensions.

The arrow consists of a cylindrical body extending from the start point towards the end, and a conical tip at the end point. If the distance between start and end is less than or equal to the tip length, only the cone tip is rendered.

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

tipRadius - the radius of the cone base at the tip

tipLength - the length of the conical tip

segments - the number of segments for cylinder and cone smoothness. Higher values create smoother arrows. Minimum is 3.

appearance - the line appearance (color, width) used for all lines
