Constructor Detail

PickConeSegment

public PickConeSegment()

Constructs an empty PickConeSegment. The origin and end point of the cone are initialized to (0,0,0). The spread angle is initialized to PI/64 radians.

PickConeSegment

public PickConeSegment(Point3d origin,
                       Point3d end,
                       double spreadAngle)

Constructs a finite cone pick shape from the specified parameters.

Parameters:

origin - the origin of the cone

end - the end of the cone along the direction vector

spreadAngle - the spread angle of the cone in radians

Method Detail

set

public void set(Point3d origin,
                Point3d end,
                double spreadAngle)

Sets the parameters of this PickCone to the specified values.

Parameters:

origin - the origin of the cone

end - the end of the cone

spreadAngle - the spread angle of the cone in radians

getEnd

public void getEnd(Point3d end)

Gets the end point of this PickConeSegment.

Parameters:

end - the Point3d object into which the end point will be copied.
