  ## Utility functions

The following utility functions are available\

- void GLwBeginProjection (Widget w)

  - void GLwEndProjection (void)

  The following code snippet selects perspective projection for the workstation *ws*:

  ```
          GLwBeginProjection (ws);
            glFrustum (-1.0, 1.0, -1.0, 1.0, 1.0, 10.0);
          GLwEndProjection ();
  ```

  During redisplay, this will be executed as a display list with the matrix mode set to *GL\_PROJECTION* and an identity matrix on top of the projection matrix stack.\

- void GLwPostProjectionList (Widget w, GLuint p)

  - void GLwPostProjectionMatrix (Widget w, GLdouble \*m)

  - void GLwPostCurrentProjection (Widget w)

  - void GLwUnpostProjection (Widget w)

  - GLuint GLwGetProjectionList (Widget w)

  - int GLwGetProjectionMatrix (Widget w, GLdouble \*m)

  - void GLwSetFrustumProjection (Widget w, GLdouble left, GLdouble right, GLdouble bottom, GLdouble top, GLdouble near, GLdouble far)

  - void GLwSetOrthoProjection (Widget w, GLdouble left, GLdouble right, GLdouble bottom, GLdouble top, GLdouble near, GLdouble far)

  - void GLwBeginView (Widget w)

  - void GLwEndView (void)

  The following code snippet selects a view from the z-axis for the workstation *ws*:

  ```
          GLwBeginView (ws);
            gluLookAt (0.0, 0.0, 3.0,
                       0.0, 0.0, 0.0,
                       0.0, 1.0, 0.0);
          GLwEndView ();
  ```

  During redisplay, this will be executed as a display list with the matrix mode set to *GL\_MODELVIEW* and an identity matrix on top of the model view matrix stack.\

- void GLwPostViewList (Widget w, GLuint v)

  - void GLwPostViewMatrix (Widget w, GLdouble \*m)

  - void GLwPostCurrentView (Widget w)

  - void GLwUnpostView (Widget w)

  - GLuint GLwGetViewList (Widget w)

  - int GLwGetViewMatrix (Widget w, GLdouble \*m)

  - void GLwSetPolarView (Widget w, GLdouble r, GLdouble theta, GLdouble phi)

  - void GLwPostObject (Widget w, GLuint o)

  posts *object* to *w*.\

- void GLwUnpostObject (Widget w, GLuint o)

  - void GLwUnpostAllObjects (Widget w)

  - void GLwRedrawObjects (Widget w)

  force a redraw of all objects posted to *w*.
