This directory contains files from my dabblings with vector graphics and 3-D modelling prior to going blind. Best I can tell, the software used to create these is still being developed, but as these files are at least 9 years old, I cannot guarantee any of them will open properly in a current version. Also, as some of the file names are vague, human memory is faulty, and past me didn't leave many notes for present me to reference, I can't say what many of these contain. Files are divided into directories based on the software used to create them. Metasequoia is a 3-D modeller that, at the time I used it was around version 2.3 or 2.4, only ran natively under Windows, but worked with Wine as long as you avoided it's Direct3D renderer. I understand it was once quite popular among the Japanese for video games and animation. Best I can tell, it's now up to version 4 and now has an official Mac port. FreeCAD is a Free and Open Source Computer Aided Design package capable of producing models suitable for 3-D printing. I believe it was at version 0.12 or 0.13 when I used it and is now at version 0.19. I don't seem to have retained any exported stl files, and of the models here, the only one that I've had 3-D printed is the Hex Crystal. CaRMetal is a, persumably vector-based, graphics program that simulates geometric constructions with compass and Ruler(hence the CaR in the name).
