Function: calculatePolygonMomentOfInertia()

calculatePolygonMomentOfInertia(mass, verticesAboutCentroid): number

Defined in: physics/shapes/polygon-math.ts:80

Calculates the moment of inertia of a polygon for a given mass, about its own center of mass.

Parameters​

mass​

number

The mass of the body the polygon belongs to.

verticesAboutCentroid​

readonly Vector2[]

The polygon's vertices, in order, relative to its own centroid (i.e. already translated so their average, weighted by calculateCentroid, is the origin).

Returns​

number

The moment of inertia of the polygon.
