implicit function for convex set of planes
vtkPlanes computes the implicit function and function gradient for a set of planes. The planes must define a convex space.
The function value is the closest first order distance of a point to the convex region defined by the planes. The function gradient is the plane normal at the function value. Note that the normals must point outside of the convex region. Thus, a negative function value means that a point is inside the convex region.
There are several methods to define the set of planes. The most general is to supply an instance of vtkPoints and an instance of vtkDataArray. (The points define a point on the plane, and the normals corresponding plane normals.) Two other specialized ways are to 1) supply six planes defining the view frustrum of a camera, and 2) provide a bounding box.

See vtkCamera::GetFrustumPlanes() documentation.
void vtkPlanes::SetBounds | ( | const double | bounds[6] | ) |
An alternative method to specify six planes defined by a bounding box.
The bounding box is a six-vector defined as (xmin,xmax,ymin,ymax,zmin,zmax). It defines six planes orthogonal to the x-y-z coordinate axes.

double | zmin, | ||
double | zmax | ||
) |
An alternative method to specify six planes defined by a bounding box.
The bounding box is a six-vector defined as (xmin,xmax,ymin,ymax,zmin,zmax). It defines six planes orthogonal to the x-y-z coordinate axes.
int vtkPlanes::GetNumberOfPlanes | ( | ) |
Return the number of planes in the set of planes.
Create and return a pointer to a vtkPlane object at the ith position.
Asking for a plane outside the allowable range returns NULL. This method always returns the same object. Use GetPlane(int i, vtkPlane *plane) instead.
If i is within the allowable range, mutates the given plane's Normal and Origin to match the vtkPlane object at the ith position.
Does nothing if i is outside the allowable range.
