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 )



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.


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.


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