Constructor Detail

TransformOnlyDisplayRendererJ3D

public TransformOnlyDisplayRendererJ3D()

This is the DisplayRenderer used for the TRANSFORM_ONLY api. It is used for only transforming data into VisADSceneGraphObject but not rendering (and hence no interaction).

Method Detail

Create scene graph root, if none exists, with Transform and direct manipulation root; create 3-D box, lights and MouseBehaviorJ3D for embedded user interface.

Specified by:

createSceneGraph in class DisplayRendererJ3D

Parameters:

v -

vpt -

c -

Returns:

Scene graph root.
