C SPECIFICATION
void glVertex2d( 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 )

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

C SPECIFICATION
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 )

PARAMETERS
v Specifies 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.

DESCRIPTION
glVertex 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 and w
defaults to 1. When x, y, and z are specified, w defaults
to 1.

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