  GLdouble x,  GLdouble y);void glVertex2f(  GLfloat x,  GLfloat y);void glVertex2i(  GLint x,  GLint y);void glVertex2s(  GLshort x,  GLshort y);void glVertex3d(  GLdouble x,  GLdouble y,  GLdouble z);void glVertex3f(  GLfloat x,  GLfloat y,  GLfloat z);void glVertex3i(  GLint x,  GLint y,  GLint z);void glVertex3s(  GLshort x,  GLshort y,  GLshort z);void glVertex4d(  GLdouble x,  GLdouble y,  GLdouble z,  GLdouble w);void glVertex4f(  GLfloat x,  GLfloat y,  GLfloat z,  GLfloat w);void glVertex4i(  GLint x,  GLint y,  GLint z,  GLint w);void glVertex4s(  GLshort x,  GLshort y,  GLshort z,  GLshort w);

• x, y, z, w
  The x, y, z, and w coordinates of a vertex. Not all parameters are present in all forms of the command.

void glVertex2dv(
  const GLdouble *v);void glVertex2fv(  const GLfloat *v);void glVertex2iv(  const GLint *v);void glVertex2sv(  const GLshort *v);void glVertex3dv(  const GLdouble *v);void glVertex3fv(  const GLfloat *v);void glVertex3iv(  const GLint *v);void glVertex3sv(  const GLshort *v);void glVertex4dv(  const GLdouble *v);void glVertex4fv(  const GLfloat *v);void glVertex4iv(  const GLint *v);void glVertex4sv(  const GLshort *v);

• v
  A pointer to an array of two, three, or four elements. The elements of a two-element array are x and y; of a three-element array, x, y, and z; and of a four-element array, x, y, z, and w.

The glVertex function commands are used within glBegin/glEnd pairs to specify point, line, and polygon vertices. The current color, normal, and texture coordinates are associated with the vertex when glVertex is called.

When only x and y are specified, z defaults to 0.0 and w defaults to 1.0. When x, y, and z are specified, w defaults to 1.0.

Invoking glVertex outside of a glBegin/glEnd pair results in undefined behavior.

**  Windows NT/2000:** Requires Windows NT 3.5 or later.
**  Windows 95/98:** Requires Windows 95 or later. Available as a redistributable for Windows 95.
**  Header:** Declared in Gl.h.
**  Library:** Use Opengl32.lib.
