Parameters

x, y, z, w

Specify the x, y, z and w coordinates of a vertex. Not all parameters are present in all forms of the command.

v

Specify a pointer to an array of two, three, or four elements.a 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.
