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.
