Method Details

getTransformation

public double[] getTransformation()

Description copied from interface: ILcd3DMeshNode

Returns a transformation matrix that applies to this node and its children. The matrix should be 4x4 elements in column-major order. This is the same convention used by OpenGL functions such as glLoadMatrix(). null can be returned and represents the identity matrix.

Specified by:

getTransformation in interface ILcd3DMeshNode

Overrides:

getTransformation in class TLcdOpenFlightNode

Returns:

a 4x4 column-major transformation matrix, possibly null

setTransformation

public void setTransformation(double[] aMatrix4x4)

Sets this node's transformation matrix. The matrix must be 4x4 elements and be in column major form. null values are allowed, and will be more efficient than specifying an identity matrix.

Parameters:

aMatrix4x4 - a 16-element double array defining a 4x4 transformation matrix

accept

public void accept(ALcdOpenFlightSceneVisitor aVisitor)

Description copied from interface: ILcdOpenFlightNode

Accepts an OpenFlight visitor. A typical implementation of this method should call aVisitor.visit(this).

Specified by:

accept in interface ILcdOpenFlightNode

Overrides:

accept in class TLcdOpenFlightNode

Parameters:

aVisitor - the visitor to accept
