Wang et. al.](https://github.com/bernwang/LiDAR-annotator) I recommend using that instead.\n\u003e - Sorry, current version using skinny (1-pixel) marker. :( Another option is to use Three.js's built-in octotree and color entire boxes.\n\n# Usage\n\n**No installation needed!** This is an in-browser interactive view of your models.\n\n1. To *run*, double-click on `index.html` to launch the app.\n2. To *label*, simply hold your mouse down and drag across the screen.\n3. To *export* your labelled points, click on the \"save\" button to the top-left.\n\nNeed to rotate or move your point cloud? To change between `move mode` and `label mode`, click on the respective buttons in the top-left:\n- In `move mode,` dragging will reorient the point cloud. Scrolling with zoom in and out.\n- In `label mode,` dragging will added red dots, representing labelled points.\n\n# Point Cloud Format\n\n`js/output.js` defines a global variable `data`, a dictionary mapping unique point cloud names to point cloud data; point clouds have a `vertices` property, a list of vertices, each with `.x`, `.y` and `.z` properties.\n\ne.g., To access the `x` position of the first point in the point cloud named `frog`, you would access `data.frog.vertices[0].x`. Simple example of `output.js`:\n\n```\nvar data = {\n   'frog': {\n      'vertices': [\n          {'x': 3.5, 'y': 3.5, 'z': 5.6},\n          {'x': 1.0, 'y': 1.2, 'z': 3.4}\n      ]\n   }\n}\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Falvinwan%2Fantsy3d","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Falvinwan%2Fantsy3d","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Falvinwan%2Fantsy3d/lists"}
