Lightweight point cloud annotation tool for instance-level segmentation using fat markers and raytracing. Notes: This has now evolved into a more sophisticated LiDaR annotator: LiDaR Annotator by B. Wang et. al. I recommend using that instead. Sorry, current version using skinny (1-pixel) marker. :( Another option is to use Three.js's built-in octotree and color entire boxes.
