hom_mat3d_translate_local — Add a translation to a homogeneous 3D transformation matrix.
hom_mat3d_translate_local( : : HomMat3D, Tx, Ty, Tz : HomMat3DTranslate)
hom_mat3d_translate_local adds a translation by the vector t = (Tx,Ty,Tz) to the homogeneous 3D transformation matrix HomMat3D and returns the resulting matrix in HomMat3DTranslate. In contrast to hom_mat3d_translate, the translation is performed relative to the local coordinate system, i.e., the coordinate system described by HomMat3D; this corresponds to the following chain of transformation matrices:
/ 1 0 0 \ / Tx \
HomMat3DTranslate = HomMat3D * | 0 1 0 t | t = | Ty |
| 0 0 1 | \ Tz /
\ 0 0 0 1 /
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. For example, the homogeneous matrix
/ ra rb rc td \
| re rf rg th |
| ri rj rk tl |
\ 0 0 0 1 /
is stored as the tuple [ra, rb, rc, td, re, rf, rg, th, ri, rj, rk, tl].
Input transformation matrix.

Translation along the y-axis.
Default value: 64
Suggested values: 0, 16, 32, 64, 128, 256, 512, 1024

Output transformation matrix.
If the parameters are valid, the operator hom_mat3d_translate_local returns 2 (H_MSG_TRUE). If necessary, an exception is raised.
