NAME

       vpTranslate - multiply the current transformation matrix by a translation 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 default, the transformation  matrix  is
       post-multiplied  (M  =  M*T  where  M  is  the  current  matrix  and  T  is the translation matrix).  The
       VP_CONCAT_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.
