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 produces a translation by $("x","y","z")$. The current matrix (see
glMatrixMode) is multiplied by this translation matrix, with the product replacing the current matrix, as if glMultMatrix were called with the following matrix for its argument:

left ( ~ down 20 matrix {
   ccol { 1~~ above 0~~ above 0~~ above 0~~ }
   ccol { 0~~ above 1~~ above 0~~ above 0~~ }
   ccol { 0~~ above 0~~ above 1~~ above 0~~ }
   ccol { "x"~ above "y"~ above "z"~ above 1} } ~~right )

If the matrix mode is either GL_MODELVIEW or GL_PROJECTION, all objects drawn after a call to glTranslate 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.

ASSOCIATED GETS

glGet with argument GL_MATRIX_MODE
glGet with argument GL_COLOR_MATRIX
glGet with argument GL_MODELVIEW_MATRIX
glGet with argument GL_PROJECTION_MATRIX
glGet with argument GL_TEXTURE_MATRIX
