Detailed Description

evaluate implicit quadric function.

Date:
2000/12/10 20:08:17
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

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.

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.

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.

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::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::New   [static]
 

Construct quadric with all coefficients = 1.

Reimplemented from vtkObject.

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

Evaluate quadric equation.

Reimplemented from vtkImplicitFunction.

float vtkQuadric::EvaluateFunction float    x,
float    y,
float    z
[inline]
 

Reimplemented from vtkImplicitFunction.

Definition at line 70 of file vtkQuadric.h.

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

Evaluate the gradient to the quadric equation.

Reimplemented from vtkImplicitFunction.

void vtkQuadric::SetCoefficients float    a[10]
 

Set / get the 10 coefficients of the quadric equation.

void vtkQuadric::SetCoefficients float    a0,
float    a1,
float    a2,
float    a3,
float    a4,
float    a5,
float    a6,
float    a7,
float    a8,
float    a9
 

virtual float* vtkQuadric::GetCoefficients   [virtual]
 

virtual void vtkQuadric::GetCoefficients float    data[10] [virtual]
