vtkPlane provides methods for various plane computations. These include projecting points onto a plane, evaluating the plane equation, and returning plane normal. vtkPlane is a concrete implementation of the abstract class vtkImplicitFunction.
|
Return the distance of a point x to a plane defined by n(x-p0) = 0. The normal n[3] must be magnitude=1. |
|
Quick evaluation of plane equation n(x-origin)=0. |
|
Evaluate plane equation for point x[3]. Implements vtkImplicitFunction. |
|
Evaluate function gradient at point x[3]. Implements vtkImplicitFunction. |
|
Project a point x onto plane defined by origin and normal. The projected point is returned in xproj. NOTE : normal does NOT have to have magnitude 1. |
|
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 vtkImplicitFunction. |
|
Given a line defined by the two points p1,p2; and a plane defined by the normal n and point p0, compute an intersection. The parametric coordinate along the line is returned in t, and the coordinates of intersection are returned in x. A zero is returned if the plane and line are parallel. |
|
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 vtkImplicitFunction. |
|
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 vtkImplicitFunction. |
|
Construct plane passing through origin and normal to z-axis. Reimplemented from vtkObject. |
|
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 vtkImplicitFunction. |
|
Project a point x onto plane defined by origin and normal. The projected point is returned in xproj. NOTE : normal assumed to have magnitude 1. |
|
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 vtkImplicitFunction. |
|
Set/get plane normal. Plane is defined by point and normal. |
|
Set/get point through which plane passes. Plane is defined by point and normal. |
