GLVERTEX(3G) OpenGL Manual GLVERTEX(3G)
NAME
glVertex - specify a vertex
C SPECIFICATION
void glVertex2s(GLshort x, GLshort y);
void glVertex2i(GLint x, GLint y);
void glVertex2f(GLfloat x, GLfloat y);
void glVertex2d(GLdouble x, GLdouble y);
void glVertex3s(GLshort x, GLshort y, GLshort z);
void glVertex3i(GLint x, GLint y, GLint z);
void glVertex3f(GLfloat x, GLfloat y, GLfloat z);
void glVertex3d(GLdouble x, GLdouble y, GLdouble z);
void glVertex4s(GLshort x, GLshort y, GLshort z, GLshort w);
void glVertex4i(GLint x, GLint y, GLint z, GLint w);
void glVertex4f(GLfloat x, GLfloat y, GLfloat z, GLfloat w);
void glVertex4d(GLdouble x, GLdouble y, GLdouble z, GLdouble w);
PARAMETERS
x, y, z, w
Specify x, y, z, and w coordinates of a vertex. Not all parameters are present in all
forms of the command.
C SPECIFICATION
void glVertex2sv(const GLshort * v);
void glVertex2iv(const GLint * v);
void glVertex2fv(const GLfloat * v);
void glVertex2dv(const GLdouble * v);
void glVertex3sv(const GLshort * v);
void glVertex3iv(const GLint * v);
void glVertex3fv(const GLfloat * v);
void glVertex3dv(const GLdouble * v);
void glVertex4sv(const GLshort * v);
void glVertex4iv(const GLint * v);
void glVertex4fv(const GLfloat * v);
void glVertex4dv(const GLdouble * v);
PARAMETERS
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.
DESCRIPTION
glVertex commands are used within glBegin()/glEnd() pairs to specify point, line, and
polygon vertices. The current color, normal, texture coordinates, and fog coordinate 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.
NOTES
Invoking glVertex outside of a glBegin()/glEnd() pair results in undefined behavior.
