Surface

public class Cylinder
extends AbstractSurface

A Cylinder object represents a cylinder in 3d space.

Constructor Summary

Cylinder()
Constructs a Cylinder object that represents a cylinder with a base radius of 1.0, with base at the origin, that is black.

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

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

Method Summary

Vector	getNormalAt(Vector point) Returns a Vector object that represents the vector normal to the 3d surface at the point represented by the specified Vector object.
boolean	intersect(Ray ray) Returns true if the ray intersects the 3d surface 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 cylinder represented by this Cylinder object occurs.
