NAME

       glFogCoord - set the current fog coordinates

C SPECIFICATION

       void glFogCoordd(GLdouble coord);

       void glFogCoordf(GLfloat coord);

PARAMETERS

       coord
	   Specify the fog distance.

C SPECIFICATION

       void glFogCoorddv(GLdouble * coord);

       void glFogCoordfv(GLfloat * coord);

PARAMETERS

       coord
	   Specifies a pointer to an array containing a single value representing the fog distance.

DESCRIPTION

       glFogCoord specifies the fog coordinate that is associated with each vertex and the current raster position. The value specified is
       interpolated and used in computing the fog color (see glFog()).

NOTES

       glFogCoord is available only if the GL version is 1.4 or greater.

       The current fog coordinate can be updated at any time. In particular, glFogCoord can be called between a call to glBegin() and the
       corresponding call to glEnd().

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.
