# Function getScaling

-   getScaling(out: [vec3](https://docs.maptiler.com/sdk-js/api-reference/types/Externals.vec3/), mat: [ReadonlyMat4](https://docs.maptiler.com/sdk-js/api-reference/types/Externals.ReadonlyMat4/)): [vec3](https://docs.maptiler.com/sdk-js/api-reference/types/Externals.vec3/)[](#getscaling)
    
    Returns the scaling factor component of a transformation matrix. If a matrix is built with fromRotationTranslationScale with a normalized Quaternion parameter, the returned vector will be the same as the scaling vector originally supplied.
