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.
