public class WireframeSphere
extends AbstractCompositeShape

A wireframe sphere approximation built from rings of connected line segments. The sphere is generated using parametric spherical coordinates, producing a latitude-longitude grid of vertices connected by lines.

The sphere is divided into 20 longitudinal slices and 20 latitudinal rings (using a step of PI / 10 radians). Adjacent vertices within each ring are connected, and corresponding vertices between consecutive rings are also connected, forming a mesh that approximates a sphere surface.

Usage example:

LineAppearance appearance = new LineAppearance(1, Color.WHITE);
WireframeSphere sphere = new WireframeSphere(new Point3D(0, 0, 300), 100f, appearance);
shapeCollection.addShape(sphere);

Constructor Details

WireframeSphere

public WireframeSphere(Point3D location,
 float radius,
 LineAppearance lineFactory)

Constructs a wireframe sphere at the given location with the specified radius. The sphere is approximated by a grid of line segments generated from parametric spherical coordinates.

Parameters:

location - the center point of the sphere in 3D space

radius - the radius of the sphere

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