+ Not all parameters are present in all forms of the command.

C Specification
void glVertex2sv( | const GLshort * Â | v); |
void glVertex2iv( | const GLint * Â | v); |
void glVertex2fv( | const GLfloat * Â | v); |
void glVertex2dv( | const GLdouble * Â | v); |
void glVertex3sv( | const GLshort * Â | v); |
void glVertex3iv( | const GLint * Â | v); |
void glVertex3fv( | const GLfloat * Â | v); |
void glVertex3dv( | const GLdouble * Â | v); |
void glVertex4sv( | const GLshort * Â | v); |
void glVertex4iv( | const GLint * Â | v); |
void glVertex4fv( | const GLfloat * Â | v); |
void glVertex4dv( | const GLdouble * Â | 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, texture
+ coordinates, and fog coordinate 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.
