From https://www.humus.name/Articles/Persson_GraphicsGemsForGames.pdf Phone-wire AA Siggraph 2012 presentation, Emil Persson, Avalanche Studios

Phone wires are long cylinder shapes, define center points, normal and radius
Avoid going sub-pixel by clamping radius to half-pixel size, then fade with radius reduction ratio to simulate sub-pixel coverage.
Also useful for railings, bars, antenna towers etc.
Still need to apply MSAA or other AA solution on top to smooth jaggies

// compute view-space w
float w = dot(viewproj[3], float4(In.Position.xyz, 1.0f));

Typical GitHub repository setup consists of at least two repositories, the upstream and the fork. Sometimes a third personal repository can also be useful. Here's how I typically name and setup my Git remote repositories:

Clone the origin repository which is usually a fork where a team does work before merging it into the main upstream repository

λ git clone https://github.com/aws-lumberyard-dev/o3de.git
λ cd o3de

SizeBench

A GUI tool for analyzing and diffing .dll and .exe files

DUMPBIN

Command line tool taht comes with Visual Studio for dumping symbols and general information about .lib files
