43 // Suppose that T(t) is a time-variant 4-by-4 transformation matrix
44 // whos values at certain points, given in the vector DataPoints, are
45 // given in the vector DataValues. This operation, then, interpolates
46 // to find the values of T at the intermediate points given in the
47 // vector InterpolationPoints.
48 //
49 // The interpolated values are found in two different ways depending
50 // on the value of the InterpolationMethod string:
51 // 1. InterpolationMethod == "closest point": In this case, the
52 // value at a given point is set to the value at the nearest
53 // neighboring point with a known value.
54 // 2. InterpolationMethod == "linear": In this case, the rotation
55 // part of the transformation matrix is found using the slerp
56 // (spherical linear interpolation), while the translation part
57 // is found using ordinary linear interpolation.
