GLTRANSLATE() MachTen Programmer’s Manual 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 )

delim $$

PARAMETERS
x, y, z
Specify the x, y, and z coordinates of a transla-
tion 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 untrans- lated coordinate system.

ERRORS
GL_INVALID_OPERATION is generated if glTranslate is exe-
cuted between the execution of glBegin and the correspond-
ing execution of glEnd.

ASSOCIATED GETS
glGet with argument GL_MATRIX_MODE
glGet with argument GL_MODELVIEW_MATRIX
glGet with argument GL_PROJECTION_MATRIX
glGet with argument GL_TEXTURE_MATRIX
