glVertex4f function

Specifies a vertex.

Syntax

void WINAPI glVertex4f(
   GLfloat x,
   GLfloat y,
   GLfloat z,
   GLfloat w
);

Parameters

x

Specifies the x-coordinate of a vertex.

y

Specifies the y-coordinate of a vertex.

z

Specifies the z-coordinate of a vertex.

w

Specifies the w-coordinate of a vertex.

Return value

This function does not return a value.

Remarks

The glVertex function 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 0.0 and w defaults to 1.0. When x, y, and z are specified, w defaults to 1.0. Invoking glVertex outside of a glBegin/glEnd pair results in undefined behavior.
