// .NAME vtkPlaneSource - create an array of quadrilaterals located in a plane
// .SECTION Description
// vtkPlaneSource creates an m x n array of quadrilaterals arranged as
// a regular tiling in a plane. The plane is defined by specifying an
// origin point, and then two other points that, together with the
// origin, define two axes for the plane. These axes do not have to be
// orthogonal - so you can create a parallelogram. (The axes must not
// be parallel.) By default, the plane is centered at the origin and
// perpendicular to the z-axis, with width and height of length 1. The
// resolution of the plane (i.e., number of subdivisions) is
// controlled by the ivars XResolution and YResolution.
//
// There are three convenience methods that allow you to easily move the
// plane. The first, SetNormal(), allows you to specify the plane
// normal. The effect of this method is to rotate the plane around the center
// of the plane, aligning the plane normal with the specified normal. The
// rotation is about the axis defined by the cross product of the current
// normal with the new normal. The second, SetCenter(), translates the center
// of the plane to the specified center point. The third method, Push(),
// allows you to translate the plane along the plane normal by the distance
// specified. (Negative Push values translate the plane in the negative
// normal direction.) Note that the SetNormal(), SetCenter() and Push()
// methods modify the Origin, Point1, and/or Point2 instance variables.
// .SECTION Caveats
// The normal to the plane will point in the direction of the cross product
// of the first axis (Origin->Point1) with the second (Origin->Point2). This
// also affects the normals to the generated polygons.
