Interface TransformationManager

All Known Implementing Classes:

TransformationManagerImpl

public interface TransformationManager

This is an interface for a transformation manager. The transformation manager is used to manage transformation applied to vertex data sent for drawing. Coordinate are in first multiplied by the matrix at the top of ModelView matrix stack. And then, the result is multiplied by the matrix at the top of Projection matrix stack. 'Projection' and 'ModelView' name refers to OpenGl 1.1. The rendered vertex are in the box [-1, 1]??.
