treat a volume as if it were an implicit function
vtkImplicitVolume treats a volume (e.g., structured point dataset) as if it were an implicit function. This means it computes a function value and gradient. vtkImplicitVolume is a concrete implementation of vtkImplicitFunction.
vtkImplicitDataSet computes the function (at the point x) by performing cell interpolation. That is, it finds the cell containing x, and then uses the cell's interpolation functions to compute an interpolated scalar value at x. (A similar approach is used to find the gradient, if requested.) Points outside of the dataset are assigned the value of the ivar OutValue, and the gradient value OutGradient.

Construct an vtkImplicitVolume with no initial volume; the OutValue set to a large negative number; and the OutGradient set to (0,0,1).
unsigned long vtkImplicitVolume::GetMTime | ( | ) |
Returns the mtime also considering the volume. This also calls Update on the volume, and it therefore must be called before the function is evaluated.
double vtkImplicitVolume::EvaluateFunction | ( | double | x[3] | ) |
Evaluate the ImplicitVolume. This returns the interpolated scalar value at x[3].
|
inline |
Evaluate the ImplicitVolume. This returns the interpolated scalar value at x[3].

Evaluate ImplicitVolume gradient.
