Surface

public class Cone

extends AbstractSurface

A Cone object represents a cone in 3d space.

Constructor Summary

Cone()
Constructs a Cone object that represents a cone with a base radius of 1.0, centered at the origin, that is black.

Cone(Vector location, double radius)
Constructs a Cone object that represents a cone with the specified base radius, and the specified location, that is black.

Cone(Vector location, double radius, RGB color)
Constructs a Cone object that represents a cone with the specified base radius, location, and color.

Method Summary

Vector	getNormalAt(Vector point) Returns a Vector object that represents the vector normal to this cone at the point represented by the specified Vector object.
boolean	intersect(Ray ray) Returns true if the ray represented by the specified Ray object intersects the cone represented by this Cone object in real space.
Intersection	intersectAt(Ray ray) Returns an Intersection object representing the points along the ray represented by the specified Ray object that intersection between the ray and the cone represented by this Cone object occurs.
