Detailed Description
implicit function for an halo
vtkImplicitHalo evaluates to 1.0 for each position in the sphere of a given center and radius Radius*(1-FadeOut). It evaluates to 0.0 for each position out the sphere of a given Center and radius Radius. It fades out linearly from 1.0 to 0.0 for points in a radius from Radius*(1-FadeOut) to Radius. vtkImplicitHalo is a concrete implementation of vtkImplicitFunction. It is useful as an input to vtkSampleFunction to generate an 2D image of an halo. It is used this way by vtkShadowMapPass.
- Warning:
- It does not implement the gradient.

| static vtkImplicitHalo* vtkImplicitHalo::New | ( | ) | [static] |
Center=(0.0,0.0,0.0), Radius=1.0, FadeOut=0.01
Reimplemented from vtkObject.
| static int vtkImplicitHalo::IsTypeOf | ( | const char * | name | ) | [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] |
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.
| virtual double vtkImplicitHalo::EvaluateFunction | ( | double | x[3] | ) | [virtual] |
Evaluate the equation.
Implements vtkImplicitFunction.
| virtual double vtkImplicitHalo::EvaluateFunction | ( | double | x, |
| double | y, | ||
| double | z | ||
| ) | [inline, virtual] |
Evaluate the equation.
