62

PARAMETERS

64       v
65           Specifies a pointer to an array of two, three, or four elements.
66           The elements of a two-element array are x and y; of a three-element
67           array, x, y, and z; and of a four-element array, x, y, z, and w.
68

DESCRIPTION

70       glVertex commands are used within glBegin()/glEnd() pairs to specify
71       point, line, and polygon vertices. The current color, normal, texture
72       coordinates, and fog coordinate are associated with the vertex when
73       glVertex is called.
74
75       When only x and y are specified, z defaults to 0 and w defaults to 1.
76       When x, y, and z are specified, w defaults to 1.
77

NOTES

79       Invoking glVertex outside of a glBegin()/glEnd() pair results in
80       undefined behavior.
