[I can always be wrong about boost it is HUGE] But the Gnu scientific library, has the structure for coordinate transforms (all the matrix stuff + differentuals). And the octave library, (which needs a little care to extract) has a host of coordinate transforms. Coordinate System Library? 15 Years Ago by daviddoria Anyone know a good, simple set of classes to do thing like cartesian to spherical conversion, coordinate system transformations, etc?
