glTranslate

NAME

glTranslated, glTranslatef -- multiply the current matrix by a translation matrix

C SPECIFICATION

void glTranslated(GLdouble x,

GLdouble y,

GLdouble z)

void glTranslatef(GLfloat x,

GLfloat y,

GLfloat z)

PARAMETERS

x, y, z

Specify the x, y, and z coordinates of a translation vector.

DESCRIPTION

glTranslate moves the coordinate system origin to the point specified by (x, y, z). The translation vector is used to compute a 4x4 translation matrix:

The current matrix (see glMatrixMode) is multiplied by this translation matrix, with the product replacing the current matrix. That is, if M is the current matrix and T is the translation matrix, then M is replaced with M * T.

If the matrix mode is either GL_MODELVIEW or GL_PROJECTION, all objects drawn after glTranslate is called are translated. Use glPushMatrix and glPopMatrix to save and restore the untranslated coordinate system.

ERRORS

GL_INVALID_OPERATION is generated if glTranslate is executed between the execution of glBegin and the corresponding execution of glEnd.
