Detailed Description

implicit sum of other implicit functions

vtkImplicitSum produces a linear combination of other implicit functions. The contribution of each function is weighted by a scalar coefficient. The NormalizeByWeight option normalizes the output so that the scalar weights add up to 1. Note that this function gives accurate sums and gradients only if the input functions are linear.

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.

◆ SetNormalizeByWeight()

virtual void vtkImplicitSum::SetNormalizeByWeight ( vtkTypeBool  )

virtual

When calculating the function and gradient values of the composite function, setting NormalizeByWeight on will divide the final result by the total weight of the component functions.
