 # libbwabstraction
-Source of paper "Scale-aware Black-and-White Abstraction of 3D Shapes" in SIGGRAPH 2018.
+Code for the paper "Scale-aware Black-and-White Abstraction of 3D Shapes" in SIGGRAPH 2018. Please visit [our project webpage](https://cgv.cs.nthu.edu.tw/projects/Shape_Analysis/BW_Abstraction) to learn more about this paper.
+
+## Features
+
+#### C++ Library
+The algorithm described in our paper is wrapped inside a simple, easy-to-use C++ interface. Check this snippet out:
+
+```C++
+  // initialize data structures for libbwabstraction
+  bwabstraction::Parameters param;
+  bwabstraction::BWAbstraction bwa;
+  bwabstraction::Result result;
+
+  // load camera mvp and model file
+  param.LoadMVPMatrixFromFile("camera.txt");
+  bwa.LoadModel("model.obj", param);
+
+  // render with desired parameters
+  param.renderWidth = 3200;
+  param.rednerHeight = 2400; // just to show a few options...
+  bwa.Render(&result, param);
+
+  // the results are available as cv::Mat images
+  cv::imwrite("bwaImage.png", result.bwaImage);
+```
+
+#### Example Code & CLI Tool
+We have documented example codes and a CLI tool for easy use. The tool works like:
+
+`> bwa_cli model.obj camera.txt bwaImage.png --scale=0.8`
+
+#### GUI Tool
+Further more, a Qt-based GUI tool is provided for quick visualization and interactive control of the algorithm.

+
+## Prebuilt Binary
+We provide Windows prebuilt binaries, including example code executable, command line tool, GUI tools and development library. Take a look at the [latest release](https://github.com/unlin/libbwabstraction/releases/latest)!
+
+## Compile
+If the prebuilt binaries are not good enough for you, we also provide configured build script for you. Everything can be built on both Windows x64 and MacOSX.
+
+#### Dependencies
+Before you can compile the library, the following dependency libraries should be installed on your system.
+* [Boost C++ Libaries](https://www.boost.org/)
+* [CGAL](https://www.cgal.org/)
+* [Eigen](http://eigen.tuxfamily.org/)
+* [GLEW](http://glew.sourceforge.net/)
+* [GLFW](https://www.glfw.org/)
+* [glm](https://glm.g-truc.net/)
+* [OpenCV](https://opencv.org/)

+* [cxxopts](https://github.com/jarro2783/cxxopts)
+
+#### Windows x64
+Use the Visual Studio 2015 solution `/vc14/libbwabstraction.sln`. Two configurations are available: x64 Debug and x64 Release. For the Qt GUI application, use the Qt project `/tools/qtgui/qtgui.pro`.
+
+#### MacOSX
+Use [CMake](https://cmake.org/) to build the provided `/cmakelist.txt`. For the Qt GUI application, use the Qt project `/tools/qtgui/qtgui.pro`.
