Determine if transformation is rigid transformation
Check If 2-D Transformation Is Rigid
affine2d object that defines a pure
A = [ 1 0 0 0 1 0 40 40 1 ]; tform = affine2d(A)
tform = affine2d with properties: T: [3x3 double] Dimensionality: 2
Test if it is a rigid transformation.
tf = isRigid(tform)
tf = 1
Check If 3-D Transformation Is Rigid
affine3d object that defines a different
scale factor in each dimension.
Sx = 1.2; Sy = 1.6; Sz = 2.4; tform = affine3d([Sx 0 0 0; 0 Sy 0 0; 0 0 Sz 0; 0 0 0 1])
tform = affine3d with properties: T: [4x4 double] Dimensionality: 3
Check if the transformation is rigid.
TF = isRigid(tform)
TF = 0
A rigid transformation includes only rotation and translation. It does not include reflection, and it does not modify the size or shape of an input object.
