As a result, the filter provides a smoothed mesh, while keeping its important curvatures.\n\n![example1](doc/bunny-results.png)\n\n## Compile\n\n### Linux\n\nYou need the dependencies: gcc, g++, make, GLFW, GLEW, libgl, libpng-dev and zlib-dev.\n\nTo compile simply run:\n\n```bash\n$ make\n```\n\nand the binary `bin/gimmesh` will be created.\n\n### OS X\n\nYou need the dependencies: gcc, g++, make, GLFW, GLEW and the OpenGL framework.\n\nTo compile simply run:\n\n```bash\n$ make\n```\n\nand the binary `bin/gimmesh` will be created.\n\n## Usage\n\nTo use this tool, you must provide a geometry image. They are represented as `.gim` files with the following format, in order:\n\n- Image Width: 4-bytes integer\n- Image Height: 4-bytes integer\n- Image Data: each pixel is represented as a 3-channel 4-byte float (RGB), totalizing 12 bytes per pixel. Total data size is (width * height * 3 (channels) * 4) bytes.\n\n\nA set of example geometry images are available in the res/ folder.\n\nTo open the application, simply run:\n\n```bash\n$ ./bin/gimmesh -g \u003cexample.gim\u003e\n```\n\nAn iterative GUI will be opened and you will be able to filter the geometry image.\n\n## Wavefront Objects\n\nIt is also possible to transform wavefront objects to the `.gim` format using the application.\n\nTo do that, simply run:\n\n```bash\n./bin/gimmesh -o \u003cexample.obj\u003e\n```\n\nYou can also set the optional parameters:\n\n```\n-e \u003cresult.gim\u003e\t: specify the path of the geometry image that will be generated (default: ./export.gim)\n-it \u003cnumber\u003e\t: number of iterations for spherical parametrization algorithm (default: 500)\n-s \u003cnumber\u003e\t: size of geometry image (\u003cn\u003e x \u003cn\u003e) [must be an odd number] (default: 255)\n```\n\n\u003e Note: The parametrization used to transform meshes to geometry images still needs to be improved. Thus, the quality of the result will depend on the input mesh.\n\n\n## References\n\n- [1] https://www.sciencedirect.com/science/article/abs/pii/S0097849320301503.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffelipeek%2Fdt-sgim","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ffelipeek%2Fdt-sgim","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffelipeek%2Fdt-sgim/lists"}
