winding_number()

float MayaFlux::Kinesis::winding_number ( std::span< const glm::vec2 >  path )

inlinenoexcept

Net revolutions a path turned through.

Parameters

path	Positions in chronological order

Returns

signed_turning divided by two pi

Reads directly as a count: near 1 for one counterclockwise loop, near -1 for one clockwise loop, near 0 for a path that returned to its starting heading without net rotation.
