javax.media.j3d.TransformGroup
Group node that contains a transform. The TransformGroup node specifies a single spatial transformation, via a Transform3D object, that can position, orient, and scale all of its children.
The specified transformation must be affine. Further, if the TransformGroup node is used as an ancestor of a ViewPlatform node in the scene graph, the transformation must be congruent-only rotations, translations, and uniform scales are allowed in a direct path from a Locale to a ViewPlatform node.
Note: Even though arbitrary affine transformations are allowed, better performance will result if all matrices within a branch graph are congruent, containing only rotations translation, and uniform scale.
The effects of transformations in the scene graph are cumulative. The concatenation of the transformations of each TransformGroup in a direct path from the Locale to a Leaf node defines a composite model transformation (CMT) that takes points in that Leaf node's local coordinates and transforms them into Virtual World (Vworld) coordinates. This composite transformation is used to transform points, normals, and distances into Vworld coordinates. Points are transformed by the CMT. Normals are transformed by the inverse-transpose of the CMT. Distances are transformed by the scale of the CMT. In the case of a transformation containing a nonuniform scale or shear, the maximum scale value in any direction is used. This ensures, for example, that a transformed bounding sphere, which is specified as a point and a radius, continues to enclose all objects that are also transformed using a nonuniform scale.
