SUBROUTINE fglVertex4dv( CHARACTER*8 v )
SUBROUTINE fglVertex4fv( CHARACTER*8 v )
SUBROUTINE fglVertex4iv( CHARACTER*8 v )
SUBROUTINE fglVertex4sv( CHARACTER*8 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
fglVertex commands are used within fglBegin/fglEnd pairs to specify
point, line, and polygon vertices. The current color, normal, and
texture coordinates are associated with the vertex when fglVertex 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 fglVertex outside of a fglBegin/fglEnd pair results in undefined
behavior.
