glTranslatef function

The glTranslatef function multiplies the current matrix by a translation matrix.

Syntax

void WINAPI glTranslatef(
   GLfloat x,
   GLfloat y,
   GLfloat z
);

Parameters

x

The x coordinate of a translation vector.

y

The y coordinate of a translation vector.

z

The z coordinate of a translation vector.

Return value

This function does not return a value.

Remarks

The glTranslatef function produces the translation 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 glTranslatef is called are translated. Use glPushMatrix and glPopMatrix to save and restore the untranslated coordinate system.
