 This project also provides libraries that can be easily integrated into other projects. Here's a quick start code for using the libraries. An example of [CPU](https://github.com/theICTlab/3DUNDERWORLD-SLS-GPU_CPU/blob/dev/src/app/App.cpp) and [GPU](https://github.com/theICTlab/3DUNDERWORLD-SLS-GPU_CPU/blob/dev/src/app/App_CUDA.cu) applications are included in the repository.

 ## Known issues
 
 Since there's no good API for cameras, the camera acquisition is not implemented. However, interfaces are provided.
 We welcome you to implement your camera class and make a pull request to this project.
 
 Also please note that since the example data files are currently included in the repository, the size of repository is 300MB. It may take while to clone.
