Tracing real rays
Tracing real rays Revision 2020 entry by Nupo. In this video a "lasered" version of "GNSS-stylus" (search the web for it if you want to know more) is used for the first time to scan (or "raytrace") a 3D-object. The idea to scan a toilet seat originated from a legendary Amiga demo called Hardwired (released 1991) by Crionics & Silents. There was a decommissioned toilet seat lying in the shed so why not? It actually has interesting and challenging shapes. :) Brush and paper reel visible in the end of the video were also "raytraced", but there was so much hassle with them that I decided to leave the "tracing" of them out of the video. Collecting the data and generating point clouds and stuff were done by my own (QT & open source) program: https://github.com/GNSS-Stylist/GNSS-Stylus. I will probably also release the Processing sketches, objects and data in some form later (once I clean them up a little). Other programs used: - QT creator for creating the SW used to communicate with the devices and for logging/manipulating the data. - Processing 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 It was quite a rush to put this together. Started working on this wednesday and deadline for the compo is sunday 0:00. It's now about 12:30 saturday and will definitely try to not touch anything any more :). Most of the things needed were of course already ready, but SW needed some fixes and all the generating/editing/Processing sketching and stuff took it's time. Partly due to this and my lack of "stylistic" skills the production values in this video are not up to par with general demoscene-level. I tried to avoid making the video overly long and boring by leaving out most of the yada yada. But now it feels even a bit rushed(?) But well, it is what it is now, no time to fix it any more.
