vpTranslate(3) Library Functions Manual vpTranslate(3) NAME vpTranslate - multiply the current transformation matrix by a transla- tion matrix SYNOPSIS #include <volpack.h> vpResult vpTranslate(vpc, tx, ty, tz) vpContext *vpc; double *tx, *ty, *tz; ARGUMENTS vpc VolPack context from vpCreateContext. tx X component of translation vector. ty Y component of translation vector. tz Z component of translation vector. DESCRIPTION vpTranslate is used to multiply the current transformation matrix by a 4-by-4 translation matrix. The translation matrix is: 1 0 0 tx 0 1 0 ty 0 0 1 tz 0 0 0 1 Use vpCurrentMatrix to set the current transformation matrix. By de- fault, the transformation matrix is post-multiplied (M = M*T where M is the current matrix and T is the translation matrix). The VP_CON- CAT_MODE option to vpSeti can be used to select pre-multiplication. STATE VARIABLES The current matrix concatenation parameters can be retrieved with the following state variable codes (see vpGeti(3)): VP_CURRENT_MATRIX, VP_CONCAT_MODE. ERRORS The return value is always VP_OK. SEE ALSO VolPack(3), vpCreateContext(3), vpCurrentMatrix(3) VolPack vpTranslate(3)
