Frank Dellaert 707627fb3a Rot2 "named constructors" (http://www.parashift.com/c++-faq-lite/ctors.html#faq-10.8):
/** Named constructor from angle == exponential map at identity */
  static Rot2 fromAngle(double theta) { return Rot2(cos(theta),sin(theta));}

  /** Named constructor from cos(theta),sin(theta) pair, will *not* normalize! */
  static Rot2 fromCosSin(double c, double s);

  /** Named constructor that behaves as atan2, i.e., y,x order (!) and normalizes */ 
  static Rot2 atan2(double y, double x);

which are a bit more verbose, but at least won't cause hours of bug-tracking :-(

I also made most compose, inverse, and rotate functions into methods, with the global functions mostly calling the methods. Methods have privileged access to members and hence are typically much more readable.

Frank Dellaert c40760485d I think we might have a problem: is expmap<Pose2> correct? Uncomment the new test in testPose2. It does not match what is said in http://www.cis.upenn.edu/~cis610/cis610lie1.ps. 2010-02-26 06:00:58 +00:00
Richard Roberts b82d054aaa Definitions of Lie::between, Pose2::compose, expmap, and derivatives were not correct. Fixed, but changes some behavior (iSAM and CitySLAM already fixed), will send email about this change. 2010-01-26 20:00:17 +00:00

Richard Roberts 2b82ff65e7 Deriving Lie objects from a base class Lie<T>, which provides member functions to access global functions, for use in MATLAB. 2010-01-09 23:15:06 +00:00
Richard Roberts 19a3e228d7 Large refactoring - made several Lie group functions global, which used to be member functions, to treat Lie groups more uniformly. Also created Lie.h, and a preprocessor flag in numericalDerivative to change the coordinate frame derivatives are reported in. gtsam and easylib build and pass unit tests, but this will probably break other projects, which will require a few small changes to work again. Email coming in a few minutes to describe the changes. 2010-01-08 00:40:17 +00:00
Frank Dellaert 22d66df766 added manifold test 2010-01-05 14:13:51 +00:00
Richard Roberts 92b60a8543 Made 'between' derivatives in the tangent space of the solution instead of tangent space of identity, this makes Pose2 an "origin-free" manifold. 2009-12-21 16:43:23 +00:00
Richard Roberts 7161878285 Small changes: standardized constructors, added log() and unit tests, removed +,- ops, angle() changed to theta(), print functions 2009-12-18 00:09:54 +00:00
Richard Roberts 83c95f2343 Changed constructor used from Pose2(t,R) to Pose2(R,t) 2009-12-16 21:39:03 +00:00

Richard Roberts c4b60bfd65 Closing # 118: Made Pose2 use Rot2, added 'compose' for Pose2, made slight modifications to Rot2. Also added additional unit tests. This change shouldn't break anything but let me know if it does. 2009-12-14 03:02:05 +00:00
