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.
