Detailed Description

create an array of quadrilaterals located in a plane.

Revision:
1.45

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 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 ivars.

Warning:
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.

Member Function Documentation

virtual const char* vtkPlaneSource::GetClassName   [virtual]
 

Return the class name as a string. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkPolyDataSource.

virtual int vtkPlaneSource::IsA const char *    type [virtual]
 

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkPolyDataSource.

int vtkPlaneSource::IsTypeOf const char *    type [static]
 

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkPolyDataSource.

vtkPlaneSource* vtkPlaneSource::New   [static]
 

Construct plane perpendicular to z-axis, resolution 1x1, width and height 1.0, and centered at the origin.

Reimplemented from vtkPolyDataSource.

void vtkPlaneSource::PrintSelf ostream &    os,
vtkIndent    indent
[virtual]
 

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkSource.

void vtkPlaneSource::Push float    distance
 

Translate the plane in the direction of the normal by the distance specified. Negative values move the plane in the opposite direction.

vtkPlaneSource* vtkPlaneSource::SafeDownCast vtkObject   o [static]
 

Will cast the supplied object to vtkObject* is this is a safe operation (i.e., a safe downcast); otherwise NULL is returned. This method is defined in all subclasses of vtkObject with the vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkPolyDataSource.

void vtkPlaneSource::SetCenter float    x,
float    y,
float    z
 

Set/Get the center of the plane. Works in conjunction with the plane normal to position the plane. Don't use this method to define the plane. Instead, use it to move the plane to a new center point.

void vtkPlaneSource::SetNormal float    nx,
float    ny,
float    nz
 

Set/Get the plane normal. Works in conjunction with the plane center to orient the plane. Don't use this method to define the plane. Instead, use it to rotate the plane around the current center point.

virtual void vtkPlaneSource::SetOrigin float   ,
float   ,
float   
[virtual]
 

Specify a point defining the origin of the plane.

void vtkPlaneSource::SetPoint1 float    x,
float    y,
float    z
 

Specify a point defining the first axis of the plane.

void vtkPlaneSource::SetPoint2 float    x,
float    y,
float    z
 

Specify a point defining the second axis of the plane.

void vtkPlaneSource::SetResolution const int    xR,
const int    yR
 

Set the number of x-y subdivisions in the plane.

virtual void vtkPlaneSource::SetXResolution int    [virtual]
 

Specify the resolution of the plane along the first axes.

virtual void vtkPlaneSource::SetYResolution int    [virtual]
 

Specify the resolution of the plane along the second axes.
