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 as of July 2024 at least 12 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).

Addendum July, 2024:

I have added a directory for images I have generated programmatically 
via C++ code. The code produces images in .ppm ascii format, a very 
basic, but very space inefficient format that stores RGB triplets as raw 
text separated by whitespace with no indicator where each RGB triplet 
ends(though most of my code inserts a newline between triplets) or where 
rows of the image end. For this reason, I'll only be uploading the .pngs 
produced by feeding the .ppm though optipng, an optimizer for static 
images that can optimize the lossless compression on .png files and 
losslessly convert many other formats to .png, which tneds to result in 
a >95% decrease in file size for the ppm>png conversion.
