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.
