Revision:
1.2

vtkQuadric evaluates the quadric function F(x,y,z) = a0*x^2 + a1*y^2 + a2*z^2 + a3*x*y + a4*y*z + a5*x*z + a6*x + a7*y + a8*z + a9. vtkQuadric is a concrete implementation of vtkImplicitFunction.

Member Function Documentation

float vtkQuadric::EvaluateFunction float    x[3] [virtual]
 

Evaluate quadric equation.

Implements vtkImplicitFunction.

void vtkQuadric::EvaluateGradient float    x[3],
float    g[3]
[virtual]
 

Evaluate the gradient to the quadric equation.

Implements vtkImplicitFunction.

virtual const char* vtkQuadric::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 vtkImplicitFunction.

virtual int vtkQuadric::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 vtkImplicitFunction.

int vtkQuadric::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 vtkImplicitFunction.

vtkQuadric* vtkQuadric::New   [static]
 

Construct quadric with all coefficients = 1.

Reimplemented from vtkObject.

void vtkQuadric::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 vtkImplicitFunction.

vtkQuadric* vtkQuadric::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 vtkImplicitFunction.

void vtkQuadric::SetCoefficients float    a[10]
 

Set / get the 10 coefficients of the quadric equation.
