Name

hom_mat2d_identityT_hom_mat2d_identityHomMat2dIdentityhom_mat2d_identityHomMat2dIdentityHomMat2dIdentity — Generate the homogeneous transformation matrix of the identical 2D transformation.

Signature

hom_mat2d_identity( : : : HomMat2DIdentity)

hom_mat2d_identityhom_mat2d_identityHomMat2dIdentityhom_mat2d_identityHomMat2dIdentityHomMat2dIdentity generates the homogeneous transformation matrix HomMat2DIdentityHomMat2DIdentityHomMat2DIdentityHomMat2DIdentityHomMat2DIdentityhomMat2DIdentity describing the identical 2D transformation:

Attention

Note that homogeneous matrices are stored row-by-row as a tuple; the last row is not stored because it is identical for all homogeneous matrices that describe an affine transformation. Thus, HomMat2DIdentityHomMat2DIdentityHomMat2DIdentityHomMat2DIdentityHomMat2DIdentityhomMat2DIdentity is stored as the tuple [1,0,0,0,1,0].

Parallelization

Multithreading type: reentrant (runs in parallel with non-exclusive operators).
Multithreading scope: global (may be called from any thread).
Processed without parallelization.

Parameters

HomMat2DIdentityHomMat2DIdentityHomMat2DIdentityHomMat2DIdentityHomMat2DIdentityhomMat2DIdentity (output_control) hom_mat2d → (real)

Transformation matrix.

Result

hom_mat2d_identityhom_mat2d_identityHomMat2dIdentityhom_mat2d_identityHomMat2dIdentityHomMat2dIdentity always returns 2 (H_MSG_TRUE).
