Fan of Tracing Rays
Fan of Tracing Rays Hogmanay.party 2020 wild-compo entry by Nupo (choir by Torvelot) This demo is kind of continuation to "Tracing real rays" released at Revision 2020. Instead of 2 GNSS (="GPS") antennas this uses 3 antennas used to solve the orientation and location of the rig, where lidar and camera are mounted on. And instead of a laser distance measurement module, rotating lidar is used. Data from these devices can then be used to generate a point cloud that can subsequently be used to generate mesh/ meshes for objects. Collecting the data and generating point clouds and stuff were done by my (QT & open source) program: https://github.com/GNSS-Stylist/GNSS-Stylus. CGI-parts were done using Godot game engine. List of programs used: - QT creator for creating the SW used to communicate with the devices and for logging/manipulating the data. - Godot for creating CGI-parts - MeshLab for creating 3d-objects (out of the point clouds) you can see on the CGI-parts. - OpenShot for video editing - Audacity for audio editing - WinUAE to grab a video of the original demo After "Tracing real rays" I continued tinkering with GNSS-devices and then started to wonder if using this kind of rotating lidar could be feasible for scanning a 3d-object. And after a lot of thinking, coding and tinkering it seemed to be.
