RectangularComponent

public RectangularComponent(int componentId,
 double width,
 double length,
 double thickness)

Initializes a RectangularComponent centered on the origin with the direction vector parallel with the y-axis, the midpoint at the origin, the plane on the upstream face with the normal anti-parallel to the z-axis, and the line passing through the midpoints of the top and bottom faces.

Parameters:

componentId - the id of the component

width - the length along the x-axis

length - the length along the y-axis

thickness - the length along the z-axis

RectangularComponent

public RectangularComponent(int componentId,
 Point3D p0,
 Point3D p1,
 Point3D p2,
 Point3D p3,
 Point3D p4,
 Point3D p5,
 Point3D p6,
 Point3D p7)

Initializes a RectangularComponent from the given points. The line will be from the middle of the bottom face to the middle of the top face. The midpoint will be at the midpoint of the line. The direction vector will parallel the line.

Parameters:

componentId - the id of the component

p0 - 1st point of the bottom face

p1 - 2nd point of the bottom face

p2 - 3rd point of the bottom face

p3 - 4th point of the bottom face

p4 - 1st point of the top face

p5 - 2nd point of the top face

p6 - 3rd point of the top face

p7 - 4th point of the top face

Method Details

getType

public String getType()
