Constructor Detail

Object3DBranch

public Object3DBranch()

Object3DBranch

public Object3DBranch(java.lang.Object item,
                      Home home,
                      UserPreferences preferences,
                      java.lang.Object context)

Method Detail

getHome

public Home getHome()

Returns home instance or null.

getUserPreferences

public UserPreferences getUserPreferences()

Returns user preferences.

getContext

public java.lang.Object getContext()

Returns the context in which this object is used.

update

public abstract void update()

Updates this branch from the home object.

getHomeTextureClone

protected javax.media.j3d.Texture getHomeTextureClone(javax.media.j3d.Texture texture,
                                                      Home home)

Deprecated. Use getContextTexture(Texture, Object) which context parameter may be equal to different contexts for a given home

Returns a cloned instance of texture shared per home or the texture itself if home is null. As sharing textures across universes might cause some problems, it's safer to handle a copy of textures for a given home.

getContextTexture

protected javax.media.j3d.Texture getContextTexture(javax.media.j3d.Texture texture,
                                                    java.lang.Object context)

Returns a cloned instance of texture shared per context or the texture itself if context is null. As sharing textures across universes might cause some problems, it's safer to handle a copy of textures for a given context.

getShape

protected java.awt.Shape getShape(float[][] points)

Returns the closed shape matching the coordinates in points array.

getMaterial

protected javax.media.j3d.Material getMaterial(java.lang.Integer diffuseColor,
                                               java.lang.Integer ambientColor,
                                               float shininess)

Returns a shared material instance matching the given color.

getTextureAttributes

protected javax.media.j3d.TextureAttributes getTextureAttributes(HomeTexture texture)

Returns shared texture attributes matching transformation applied to the given texture.

getTextureAttributes

protected javax.media.j3d.TextureAttributes getTextureAttributes(HomeTexture texture,
                                                                 boolean scaled)

Returns shared texture attributes matching transformation applied to the given texture and scaled if required.

getTextureAttributesFittingArea

protected javax.media.j3d.TextureAttributes getTextureAttributesFittingArea(HomeTexture texture,
                                                                            float[][] areaPoints,
