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 )

delim $$  

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.
