getScaling function
Returns the scaling factor component of a transformation matrix. If a matrix is built with fromRotationTranslationScale with a normalized Quaternion paramter, the returned vector will be the same as the scaling vector originally supplied. @param {vec3} out Vector to receive scaling factor component @param {ReadonlyMat4} mat Matrix to be decomposed (input) @return {vec3} out
Implementation
List<double> getScaling(List<double> out, List<double> mat) {
final m11 = mat[0];
final m12 = mat[1];
final m13 = mat[2];
final m21 = mat[4];
final m22 = mat[5];
final m23 = mat[6];
final m31 = mat[8];
final m32 = mat[9];
final m33 = mat[10];
out[0] = hypot([m11, m12, m13]);
out[1] = hypot([m21, m22, m23]);
out[2] = hypot([m31, m32, m33]);
return out;
