Graphic, SpaceNode, TransformNode

public interface MatrixTransformNode

extends TransformNode

A stateful transform node based on matrix multiplication. In matrix notation the transform is M*g, where "M" is the transform matrix and "g" is the geometry of this graphic entity and its descendants. Of the transform node interfaces this is the most general (least constrained).

Method Detail

setGraphicTransform

public void setGraphicTransform(Matrix4 matrix)

Sets the geometric transformation matrix of this graphic entity. If the graphic is spatially constrained, some or all of the transformation may be ignored.

Parameters:

matrix - Value of the transformation. Never null.

getGraphicTransform

public Matrix4 getGraphicTransform(Matrix4 retVal)

Gets the transformation matrix of this graphic entity. If the graphic is spatially constrained, it will be reflected in the return value.

Specified by:

getGraphicTransform in interface TransformNode

Parameters:

retVal - Return value object. The matrix. Never null.

Returns:

Reference to retVal. Never null.
