void glVertex2d(
GLdouble x, GLdouble y);void glVertex2f( GLfloat x, GLfloat y);void glVertex2i( GLint x, GLint y);void glVertex2s( GLshort x, GLshort y);void glVertex3d( GLdouble x, GLdouble y, GLdouble z);void glVertex3f( GLfloat x, GLfloat y, GLfloat z);void glVertex3i( GLint x, GLint y, GLint z);void glVertex3s( GLshort x, GLshort y, GLshort z);void glVertex4d( GLdouble x, GLdouble y, GLdouble z, GLdouble w);void glVertex4f( GLfloat x, GLfloat y, GLfloat z, GLfloat w);void glVertex4i( GLint x, GLint y, GLint z, GLint w);void glVertex4s( GLshort x, GLshort y, GLshort z, GLshort w);
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.
Requirements
** 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.
