John Carmack’s fast inverse square root function is a famous algorithm used in computer graphics, particularly in 3D rendering, to compute the inverse square root of a number quickly.
It was notably used in the Quake III Arena game engine to speed up computations related to lighting, shading, and physics. The function approximates the value of 1/sqrt(x) very efficiently, significantly faster than the traditional method of calculating a square root followed by division.
A helper function that creates a 1-click MCP install link for Cursor using URL-based authentication with Xano MCP Servers. This function generates deeplinks and various markup formats (Markdown, HTML, JSX) that allow users to install MCP servers directly into Cursor with a single click.
