Method GL.glVertex()

Method glVertex

void glVertex(float|int|array(float|int) x, float|int|void y, float|int|void z, float|int|void 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.

Parameter x

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

Parameter 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.
