public class Cone

extends javax.media.j3d.Shape3D

A simple cone that uses triangles.

The created cone does not have any capabilities set except for the ability to write the geometry - needed so that we can modify the geometry when you change the height or radius. If you know that you are not going to be changing the geometry you can turn this off.

As we assume you may want to use this as a collidable object, we store the GeometryData instance that is used to create the object in the userData of the underlying TriangleArray. The geometry does not have texture coordinates set.

Constructor Detail

Cone

public Cone()

Construct a default cone with no appearance set. The default size of the cone is:
Height: 2.0
Radius: 1.0
Faces: 16

Cone

public Cone(javax.media.j3d.Appearance app)

Construct a default cone with the given appearance. The default size of the cone is:
Height: 2.0
Radius: 1.0
Faces: 16

Parameters:

app - The appearance to use

Cone

public Cone(int faces)

Construct a default cone with no appearance set and a custom number of faces.
Height: 2.0
Radius: 1.0

Parameters:

faces - The number of faces to use around the side

Cone

public Cone(float height,
            float radius)

Construct a default cone with no appearance set. The height and radius as set to the new value and uses the default face count of 16.

Parameters:

height - The height of the cone

radius - The radius of the base of the cone

Cone

public Cone(int faces,
            javax.media.j3d.Appearance app)

Construct a default cone with the given appearance and a custom number of faces.
Height: 2.0
Radius: 1.0

Parameters:

faces - The number of faces to use around the side

app - The appearance to use

Cone

public Cone(float height,
            float radius,
            javax.media.j3d.Appearance app)

Construct a default cone with the given appearance. The height and radius as set to the new value and uses the default face count of 16.

Parameters:

height - The height of the cone

radius - The radius of the base of the cone

app - The appearance to use

Cone

public Cone(float height,
            float radius,
            int faces,
            javax.media.j3d.Appearance app)

Construct a cone with all the values customisable

Parameters:

height - The height of the cone

radius - The radius of the base of the cone

faces - The number of faces to use around the side

app - The appearance to use

Method Detail

setDimensions

public void setDimensions(float height,
                          float radius)

Change the radius and height of the cone to the new values. If the geometry write capability has been turned off, this will not do anything.

Parameters:

height - The height of the cone

radius - The radius of the base of the cone

setFacetCount

public void setFacetCount(int faces)

Set the facet count of the cone to the new value. If the geometry write capability has been turned off, this will not do anything.

Parameters:

faces - The number of faces to use around the side
