Parameters
- x, y, z, w
- The x, y, z, and w coordinates of a vertex. Not all parameters are present in all forms of the command.
void glVertex2dv(
const GLdouble *v
);
void glVertex2fv(
const GLfloat *v
);
void glVertex2iv(
const GLint *v
);
void glVertex2sv(
const GLshort *v
);
void glVertex3dv(
const GLdouble *v
);
void glVertex3fv(
const GLfloat *v
);
void glVertex3iv(
const GLint *v
);
void glVertex3sv(
const GLshort *v
);
void glVertex4dv(
const GLdouble *v
);
void glVertex4fv(
const GLfloat *v
);
void glVertex4iv(
const GLint *v
);
void glVertex4sv(
const GLshort *v
);
Parameters
- v
- 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.
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.
Windows NT/2000: Requires Windows NT 3.5 or later.
Windows 95/98: Requires Windows 95 or later. Available as a redistributable for Windows 95.
Header: Declared in Gl.h.
Library: Use Opengl32.lib.
