Interface TransformPickTarget

All Superinterfaces:

PickTarget

All Known Implementing Classes:

PixelTransform, TransformGroup

public interface TransformPickTarget
extends PickTarget

A picking target that contains a local transformation service.

This interface is used by programmers that require fairly complex implementation logic at the point of picking (eg a billboarded object that should be pickable from any direction, even though it is represented as a plane facing the current viewpoint location).

Implementor Guidelines

There is no requirement that the picking and rendering subgraphs look the same. There may be less pickable children than renderable children, so don't automatically assume that there is.

Typically this is combined with the GroupPickTarget to represent transformed sets of children, such as the TransformGroup node.
