Description

hom_mat3d_translate_localhom_mat3d_translate_localHomMat3dTranslateLocalHomMat3dTranslateLocalhom_mat3d_translate_local adds a translation by the vector t = (TxTxTxtxtx,TyTyTytyty,TzTzTztztz) to the homogeneous 3D transformation matrix HomMat3DHomMat3DHomMat3DhomMat3Dhom_mat_3d and returns the resulting matrix in HomMat3DTranslateHomMat3DTranslateHomMat3DTranslatehomMat3DTranslatehom_mat_3dtranslate. In contrast to hom_mat3d_translatehom_mat3d_translateHomMat3dTranslateHomMat3dTranslatehom_mat3d_translate, the translation is performed relative to the local coordinate system, i.e., the coordinate system described by HomMat3DHomMat3DHomMat3DhomMat3Dhom_mat_3d; this corresponds to the following chain of transformation matrices:

Attention

Note that homogeneous matrices are stored row-by-row as a tuple; the last row is usually not stored because it is identical for all homogeneous matrices that describe an affine transformation. For example, the homogeneous matrix is stored as the tuple [ra, rb, rc, td, re, rf, rg, th, ri, rj, rk, tl]. However, it is also possible to process full 4×4 matrices, which represent a projective 4D transformation.

Execution Information

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