public interface Transformation

This interface represents affine 3D coordinate transformations for an object in a graph. The preTransform is applied to the post-transformation of the object's parent in the scene hierarchy in order to obtain the transformation of the object. The postTransform is applied to this transformation in order to obtain the object's post-transformation.

Method Summary

void	postTransform(java.lang.Object object, boolean asNode, Matrix4d in, Matrix4d out, Matrix4d parent, GraphState gs) Implements the change from object's transformation in to the object's post-transformation out.
void	preTransform(java.lang.Object object, boolean asNode, Matrix4d in, Matrix4d out, GraphState gs) Implements the change from the parent's post-transformation in to the object's transformation out.

Method Detail

postTransform

void postTransform(java.lang.Object object,
                   boolean asNode,
                   Matrix4d in,
                   Matrix4d out,
                   Matrix4d parent,
                   GraphState gs)

Implements the change from object's transformation in to the object's post-transformation out.

Parameters:

object - the object for which the transformation is computed

asNode - is object a node or an edge?

in - the transformation of the object

out - the post-tranformation of the object to be computed

parent - the post-transformation of the object's parent

gs - the graph state in which the computation has to be done

preTransform

void preTransform(java.lang.Object object,
                  boolean asNode,
                  Matrix4d in,
                  Matrix4d out,
                  GraphState gs)

Implements the change from the parent's post-transformation in to the object's transformation out.

Parameters:

object - the object for which the transformation is computed

asNode - is object a node or an edge?

in - the post-transformation of the object's parent

out - the tranformation of the object to be computed

gs - the graph state in which the computation has to be done
