Constructor Detail

SelectableUniverse

SelectableUniverse()

Creates a locale, a single ViewingPlatform, and and a Viewer object (both with their default values).

See Also:

Locale, Viewer, ViewingPlatform

SelectableUniverse

SelectableUniverse(javax.media.j3d.Canvas3D canvas)

Creates a locale, a single ViewingPlatform (with default values), and and a Viewer object. The Viewer object uses default values for everything but the canvas.

Parameters:

canvas - The canvas to associate with the Viewer object. Passing in null will cause this parameter to be ignored and a canvas to be created by the utility.

See Also:

Locale, Viewer, ViewingPlatform

SelectableUniverse

SelectableUniverse(javax.media.j3d.HiResCoord origin,
                   int numTransforms,
                   javax.media.j3d.Canvas3D canvas,
                   java.net.URL userConfig)

Creates the "view" side of the scene graph. The passed in parameters override the default values where appropriate.

Parameters:

origin - The origin used to set the origin of the Locale object. If this object is null, then 0.0 is used.

numTransforms - The number of transforms to be in the MultiTransformGroup object.

canvas - The canvas to draw into. If this is null, it is ignored and a canvas will be created by the utility.

userConfig - The URL to the user's configuration file, used by the Viewer object. Passing in null causes the default values to be used.

See Also:

Locale, Viewer, ViewingPlatform, MultiTransformGroup

SelectableUniverse

SelectableUniverse(ViewingPlatform viewingPlatform,
                   Viewer viewer)

Creates the "view" side of the scene graph.

Parameters:

viewingPlatform - The viewingPlatform to use to create the "view" side of the scene graph.

viewer - The viewer object to use to create the "view" side of the scene graph.
