Detailed Description

splat points into a volume with an elliptical, Gaussian distribution

vtkGaussianSplatter is a filter that injects input points into a structured points (volume) dataset. As each point is injected, it "splats" or distributes values to nearby voxels. Data is distributed using an elliptical, Gaussian distribution function. The distribution function is modified using scalar values (expands distribution) or normals (creates ellipsoidal distribution rather than spherical).

In general, the Gaussian distribution function f(x) around a given splat point p is given by

f(x) = ScaleFactor * exp( ExponentFactor*((r/Radius)**2) )

where x is the current voxel sample point; r is the distance |x-p| ExponentFactor <= 0.0, and ScaleFactor can be multiplied by the scalar value of the point p that is currently being splatted.

If points normals are present (and NormalWarping is on), then the splat function becomes elliptical (as compared to the spherical one described by the previous equation). The Gaussian distribution function then becomes:

f(x) = ScaleFactor *
          exp( ExponentFactor*( ((rxy/E)**2 + z**2)/R**2) )

where E is a user-defined eccentricity factor that controls the elliptical shape of the splat; z is the distance of the current voxel sample point along normal N; and rxy is the distance of x in the direction perpendicular to N.

This class is typically used to convert point-valued distributions into a volume representation. The volume is then usually iso-surfaced or volume rendered to generate a visualization. It can be used to create surfaces from point distributions, or to create structure (i.e., topology) when none exists.

Warning
The input to this filter is any dataset type. This filter can be used to resample any form of data, i.e., the input data need not be unstructured.
Some voxels may never receive a contribution during the splatting process. The final value of these points can be specified with the "NullValue" instance variable.
This class has been threaded with vtkSMPTools. Using TBB or other non-sequential type (set in the CMake variable VTK_SMP_IMPLEMENTATION_TYPE) may improve performance significantly.
