factorRigidWithSignedScale Method

Test if all rows and columns are perpendicular to each other and have equal length. If so, the length (or its negative) is the scale factor from a set of rigid axes to these axes.

  • result.rigidAxes is the rigid axes (with the scale factor removed)
  • result.scale is the scale factor

factorRigidWithSignedScale(): undefined | { rigidAxes: Matrix3d, scale: number }

Returns - undefined | { rigidAxes: Matrix3d, scale: number }
