Most of the Gems in this section are concerned with transformations: how to compose, decompose, and manipulate them. The first Gem describes how to interpolate between two orientations using the quaternion representation, and adds the wrinkle of extra spins at the end of the interpolation. The fifth Gem is a useful companion to the first, in that it discusses issues relating to the choice of transformations upon which the interpolation occurs. The seventh Gem describes an alternative technique for interpolation, using Bézier curves.
The second and third Gems discuss how to decompose complex transformations into simpler components. The fourth and sixth Gems in this section describe two complementary ...
