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 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

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
);

Parameters

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.

Remarks

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.
