// integration functions that can be used within a

// Given a set of intersections (defined by the three arrays), compute

// /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.
