Class ShapeDifference

java.lang.Object
  gov.nist.microanalysis.NISTMonte.ShapeDifference

All Implemented Interfaces:

ITransform, MonteCarloSS.Shape

public class ShapeDifference
extends java.lang.Object
implements MonteCarloSS.Shape, ITransform

Implements the MonteCarloSS.Shape interface to define a Shape that represents the volume in the primary Shape that is not within the volume of the delta Shape. Creates a Shape by removing one Shape from another. ShapeDifference does not implement TrajectoryVRML.IRender as it is hard to imagine how to do this in a reasonably simple manner.

ShapeDifference

public ShapeDifference(MonteCarloSS.Shape primary,
                       MonteCarloSS.Shape delta)

MCSS_ShapeDifference - Create a Shape that represents the the primary Shape minus any overlapping regions in the delta Shape.

Parameters:

primary - Shape

delta - Shape

Method Detail

contains

public boolean contains(double[] pos)

contains - See MonteCarloSS.contains

Specified by:

contains in interface MonteCarloSS.Shape

Parameters:

pos - double[]

Returns:

boolean

getFirstIntersection

public double getFirstIntersection(double[] pos0,
                                   double[] pos1)

getFirstIntersection - See MonteCarloSS.getFirstIntersection.

rotate

public void rotate(double[] pivot,
                   double phi,
                   double theta,
                   double psi)

Description copied from interface: ITransform

rotate - Rotate the object around the specified point by phi about the z-axis followed by theta round the y-axis followed by psi around the z-axis. These is the standard Euler angle rotation. The rotation matrix is...

[	cos(phi)*cos(th)*cos(psi)-sin(phi)*sin(psi)	-sin(phi)*cos(th)*cos(psi)-cos(phi)*sin(psi)	sin(th)*cos(psi)	]
[	sin(phi)*cos(psi)+cos(phi)*cos(th)*sin(psi)	-sin(phi)*cos(th)*sin(psi)+cos(phi)*cos(psi)	sin(th)*sin(psi)	]
[	-cos(phi)*sin(th)	sin(th)*sin(phi)	cos(th)	]

Specified by:

rotate in interface ITransform

Parameters:

pivot - double[] - a three-vector specifying the point around which the rotation is performed

phi - double

theta - double

psi - double

translate

public void translate(double[] distance)

Description copied from interface: ITransform

translate - Translate this object by the distance specified.

Specified by:

translate in interface ITransform

Parameters:

distance - double[] - A three-vector specifying how much to translate
