Typical Git (O3DE) Setup

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:

  1. 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

Thin line rendering ala Avalanche

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));
