@yvesseiler - We have been considering adding support for more performance oriented LiDAR point cloud formats, such as LAS/LAZ/PCD but these are a bit overkill for common use case of the sweep's 2D data. Up until now, we have prioritized simple and human readable file formats that permit users to easily read data into external programs and convert it as they see fit.
Sweep Visualizer BETA v0.10.0 supports exporting normal 2D recordings in JSON or CSV format. It defaults to JSON with a ".scd" extension, but CSV export is possible by saving the file with a ".csv" extension manually. (ie: specifying a filename that ends in ".csv"). Both formats yield files that primarily specify a Polar coordinate and a signal strength for each sensor reading.
Internally we have been working on some large updates to the visualizer. This includes some additions to the exportation/conversion of data files, such as...
- storing points in Cartesian coordinates instead of Polar coordinates
- converting already recorded files into a different file format
- exporting subsets of recorded files (eg: scans 3-11 of a longer recording)
- combining variable number of scans from recorded files into a single more dense point cloud object
Prototyping the 3D scanner, including features like streaming scans over a network etc. has called for the consideration of new formats. We continue to investigate the benefits of existing formats.
@ajekofalltrades - This sounds like a very interesting use for the scanner. I'm excited to see what you can accomplish! Our simpler formats will lend well to simple scripting languages in programs that offer such features, but I'm guessing that VFX programs are evolving to consider point cloud information of various formats. Are there specific formats that play nice with your VFX programs?
