Parameters

x, y, z, w Specify x, y, z, and w coordinates of a vertex. Not all parameters are

present in all forms of the command.

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, 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.

Notes

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