Constructor Detail

PickCylinder

public PickCylinder()

Constructs an empty PickCylinder. The origin of the cylinder is initialized to (0,0,0). The radius is initialized to 0.

Method Detail

getOrigin

public void getOrigin(Point3d origin)

Gets the origin point of this cylinder object.

Parameters:

origin - the Point3d object into which the origin point will be copied

getRadius

public double getRadius()

Gets the radius of this cylinder object

Returns:

the radius in radians

getDirection

public void getDirection(Vector3d direction)

Gets the direction of this cylinder.

Parameters:

direction - the Vector3d object into which the direction will be copied

intersect

abstract boolean intersect(Bounds bounds,
                Point4d pickPos)

Return true if shape intersect with bounds. The point of intersection is stored in pickPos.

Specified by:

intersect in class PickShape

pointInPolytope

static boolean pointInPolytope(BoundingPolytope ptope,
                      double x,
                      double y,
                      double z)

getStartPoint

Point3d getStartPoint()

Specified by:

getStartPoint in class PickShape

getPickType

int getPickType()

Specified by:
