Detailed Description

Abstract base class for 3D transform interface.

This base class defines the interface that runtimes can implement to transform objects in 3D, for a given selection item. These include operations like:

translating an item
rotating an item
scaling an item
translating an item's rotate pivot point
translating an item's scale pivot point
returning the inclusive matrix of the item (including the item's local transformation)
returning the exclusive matrix of the item (excluding the item's local transformation)

Each operation has two calls, one with undo capability, and one without. Providing undo capability typically involves code complexity, and using undo capability incurs runtime cost in processing and memory. Therefore, non- interactive use of this interface should use calls without undo capability.

All operations on the item are done in its local coordinate system, and are absolute. It is the responsibility of the application to convert operations done in any other coordinate system (e.g. world, or another object's coordinate system) back into a UFE item's local coordinates. Similarly, the application must convert relative transformations back into absolute for the UFE item.

As with the rest of UFE, observation is done through the Observer Pattern. Observers can be added to an individual scene item, to be notified when an object's transformation changes.

To avoid the memory-consuming "one proxy object per scene object" approach, Transform3d interface objects should be obtained and used within a local scope, and not stored. Transform3d interfaces should be considered stateless, and can be bound to new selection items.
