*GL3.2 for AIX: Graphics Library (GL) Technical Reference*

## translate Subroutine

### Purpose

Translates graphical primitives.

### Libraries

Graphics Library

C (**libgl.a**)

FORTRAN (**libfgl.a**)

### C Syntax

**void translate(Coord ***x***, Coord ***y***, Coord ***z***)**

### FORTRAN Syntax

**SUBROUTINE TRANSL(***x***, ***y***, ***z***)**
**REAL ***x***, ***y***, ***z*

### Description

The** translate **subroutine moves the modeling space origin to a new point relative to the current origin. The point (x, y, z) specified by the parameters becomes the new modeling space origin. Because all drawing
primitives draw relative to the origin of the current
modeling coordinate system, all primitives called after this subroutine will appear to have been translated.

The **translate **subroutine is a modeling routine that changes the current
transformation matrix. All primitives drawn after this subroutine executes are translated. Use the **pushmatrix** and **popmatrix** subroutines to preserve an untranslated modeling space.

### Parameters

*x* |
Specifies the *x* coordinate of a point in modeling coordinates. |

*y* |
Specifies the *y* coordinate of a point in modeling coordinates. |

*z* |
Specifies the *z* coordinate of a point in modeling coordinates. |

### Example

The example C language program **backface.c** uses the **translate** modeling subroutine and alters the current transformation matrix to model the sides of a cube using a square.

### Implementation Specifics

This subroutine is part of GL in the AIXwindows Environment/6000 Version 1, Release 2 with AIXwindows/3D Feature.

### Files

**/usr/include/gl/gl.h** |
Contains C language constant and variable type definitions for GL. |

**/usr/include/gl/fgl.h** |
Contains FORTRAN constant and variable type definitions for GL. |
