Richard Roberts bf7f58112c Merge branch 'feature/isam2-cleaner-solve'		2014-02-22 20:24:17 -05:00
CppUnitLite	Swiched from isnan() check to isfinite() check for DOUBLES_EQUAL - also handles infinite case	2013-08-02 19:04:52 +00:00
cmake	Reverted reduced debug info in Profiling mode (seems to prevent inspecting source code). Fixed Profiling build not receiving build type postfixes.	2014-02-21 17:18:36 -05:00
doc	Moved coordinate frames document into GTSAM	2014-02-21 15:47:51 -05:00
examples	Added dogleg mode switch in SolverComparer	2014-02-22 17:14:20 -05:00
gtsam	Removed namespace-functions for ISAM2 optimize* and gradient*, these were only there to try to maintain a consistent interface for linear but really were not correct anyway since ISAM2 is a nonlinear object. They instead caused confusion and made the code complicated since they used a complicated system for updating and caching various components that go into calculating the solution. Replaced all this with much simpler code directly inside updateDelta, which uses clearly-defined functions in the ISAM2::Impl class to calculate the components that go into the solution. Also removed the redundant deltaUpToDate flags - now just checks whether deltaReplacedMask is empty.	2014-02-22 16:46:38 -05:00
gtsam_unstable	Removed some commented-out includes	2014-02-18 13:44:25 -05:00
matlab	covarianceEllipse now returns the matlab handle for the lines object to allow for additional formatting by the user	2014-02-09 20:34:18 -05:00
package_scripts	Parallel compilation flags in package scripts	2013-05-13 17:55:06 +00:00
tests	Removed namespace-functions for ISAM2 optimize* and gradient*, these were only there to try to maintain a consistent interface for linear but really were not correct anyway since ISAM2 is a nonlinear object. They instead caused confusion and made the code complicated since they used a complicated system for updating and caching various components that go into calculating the solution. Replaced all this with much simpler code directly inside updateDelta, which uses clearly-defined functions in the ISAM2::Impl class to calculate the components that go into the solution. Also removed the redundant deltaUpToDate flags - now just checks whether deltaReplacedMask is empty.	2014-02-22 16:46:38 -05:00
wrap	Working on standardizing/simplifying building unit tests and examples. Much simpler cmake function to add a glob of tests, doing away with convenience libraries, and removing other options that we never change from their defaults.	2014-02-13 01:34:31 -05:00
.cproject	Particle factor scaffold	2013-12-19 17:14:40 +00:00
.gitignore	Ignore Mac system files	2014-01-25 11:03:37 -05:00
.project	…
CMakeLists.txt	Fixed examples not being built due to branch "adding-scripts-simplify"	2014-02-22 17:14:01 -05:00
INSTALL	Final cleanup of text files - README.md, LICENSE*, USAGE, and INSTALL.	2014-01-30 14:42:23 -05:00
LICENSE	Final cleanup of text files - README.md, LICENSE*, USAGE, and INSTALL.	2014-01-30 14:42:23 -05:00
LICENSE.BSD	Final cleanup of text files - README.md, LICENSE*, USAGE, and INSTALL.	2014-01-30 14:42:23 -05:00
README.md	README.md edited online with Bitbucket	2014-01-30 20:37:58 +00:00
THANKS	…
USAGE	Final cleanup of text files - README.md, LICENSE*, USAGE, and INSTALL.	2014-01-30 14:42:23 -05:00
gtsam.h	new constructor, getBasis->basis, rotate and distance	2013-12-18 03:11:58 +00:00
gtsam_extra.cmake.in	Some cleanup in compiling wrappers	2013-12-12 18:37:27 +00:00

matlab.h	removed redundant shared_ptr typedefs in Cal3_S2 and Cal3_S2Stereo	2013-05-08 19:21:00 +00:00

README - Georgia Tech Smoothing and Mapping library

What is GTSAM?

GTSAM is a library of C++ classes that implement smoothing and mapping (SAM) in robotics and vision, using factor graphs and Bayes networks as the underlying computing paradigm rather than sparse matrices.

On top of the C++ library, GTSAM includes a MATLAB interface (enable GTSAM_INSTALL_MATLAB_TOOLBOX in CMake to build it). A Python interface is under development.

Quickstart

In the root library folder execute:

#!bash
$ mkdir build
$ cd build
$ cmake ..
$ make check (optional, runs unit tests)
$ make install

Prerequisites:

Boost >= 1.43 (Ubuntu: sudo apt-get install libboost-all-dev)
CMake >= 2.6 (Ubuntu: sudo apt-get install cmake)

Optional prerequisites - used automatically if findable by CMake:

Intel Threaded Building Blocks (TBB) (Ubuntu: sudo apt-get install libtbb-dev)
Intel Math Kernel Library (MKL)

Additional Information

See the INSTALL file for more detailed installation instructions.

GTSAM is open source under the BSD license, see the LICENSE and LICENSE.BSD files.

Please see the examples/ directory and the USAGE file for examples on how to use GTSAM.
