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

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.

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.
