Bounding box (bbox) visualization is supported and here is an [example](). \nPoint_viz does not need Internet connection to work (but the installation needs, of course), \nand it has been tested on Chrome and Safari with both python 2 and 3.\n\n# Usage\nTo install point_viz, simply run: `pip install point_viz`, and that's all. Below is the example of its python API:\n```\n# Import package.\nfrom point_viz import PointvizConverter\n\n# Initialize and setup output directory.\nConverter = PointvizConverter(home)\n# Pass data and create html files.\nConverter.compile(task_name, coors, default_rgb, intensity, bbox_params, bbox_color)\n```\n\n### Variables Explanation\n\n###### The `*` means optional. \n**home**: The directory where to put output html files, must be given. \\\n**task_name***: _string_, name of the output html file (can be overwritten if the name already exists; default value is \"default\").\\\n**coors***: _2-D float array_, the x, y and z coordinates of each point in the point cloud.\\\n**default_rgb***: _2-D float/int array_ of the same length as `coors`, the R, G and B colors of each point. \nIf not provided, the RGB will be automatically calculated based on `intensity` (if given) or \npoint coordinates (when `intensity` is also missing).\\\n**intensity***: _1-D float array_ of the same length as `coors`, the intensity of each point. It only takes effect when\n`default_rgb` is not given.\\\n**bbox_params***: _2-D list_, the geometry parameters of each bbox. Attributes of each row should be arranged as follows:\n\n\n| Attribute # | Description |\n|---|---|\n| 0 | Length (_float_, dimension along x-axis) |\n| 1 | Height (_float_, dimension along y-axis) |\n| 2 | Width (_float_, dimension along z-axis) |\n|3 | X coordinate of bbox centroid (_float_) |\n| 4 | Y coordinate of bbox centroid (_float_) |\n| 5 | Z coordinate of bbox centroid (_float_) |\n| 6 | Horizontal rotation regarding the +x-axis in radians (_float_) |\n| 7* | Color of the bbox (_string_, optional; [X11 color name](https://en.wikipedia.org/wiki/X11_color_names) is supported, default is \"Magenta\") |\n| 8* | Label text of the bbox (_string_, optional) |\n\n**bbox_color***: _boolean_, default is `True`. If the color of bbox is missing while the label text is given, then \n`bbox_color` has to be explicitly set to `False`. \n\n", "description_content_type": "text/markdown", "docs_url": null,
