This is the source of the Cornucopia library. This library is intended for developers who need to turn a mouse or tablet sketch stroke into a smooth curve. The basic algorithm is described in: Ilya Baran, Jaakko Lehtinen, Jovan Popovic "Sketching Clothoid Splines Using Shortest Paths", Eurographics 2010. --------- LICENSING --------- All of the source is distributed under the GNU GPL. If you would like to use it under a different license, contact me at baran37@gmail.com and I will likely grant an exemption. If you use the library for research, please cite the above paper. -------- BUILDING -------- Cornucopia itself requires Eigen 3 (http://eigen.tuxfamily.org/). As of 11/21/2010, the latest Eigen development build should work. The demonstration UI (DemoUI) was tested with Qt 4.6. There are no other dependencies. The library was tested with GCC and Visual C++ 2008 and 2010. Both 32 and 64 bits should work. The meta-build system is CMake, so standard instructions apply: make a separate build directory, run cmake from it and then use your build system. ----- USING ----- The interface is simple. The example to get started is: Test/EndToEndTest.cpp. You control the algorithm using the Parameters object that you pass in. See the Parameters.h file. If you do not want to introduce a dependency on Eigen into your application, use the API in SimpleAPI.h. Its use is also demonstrated in EndToEndTest.cpp. Oversketching is not implemented in SimpleAPI yet--you need to call fitter.setOversketchBase, passing the curve being oversketched.
