Detailed Description
performs piecewise linear ray integration.
vtkUnstructuredGridLinearRayIntegrator performs piecewise linear ray integration. Considering that transfer functions in VTK are piecewise linear, this class should give the "correct" integration under most circumstances. However, the computations performed are fairly hefty and should, for the most part, only be used as a benchmark for other, faster methods.

Given a set of intersections (defined by the three arrays), compute the peicewise integration of the array in front to back order.
/c intersectionLengths holds the lengths of each peicewise segment. /c nearIntersections and /c farIntersections hold the scalar values at the front and back of each segment. /c color should contain the RGBA value of the volume in front of the segments passed in, and the result will be placed back into /c color.

Integrates a single ray segment.
color is blended with the result (with color in front). The result is written back into color.
