The elements of a two-element array are \f2x\fP and \f2y\fP; of a three-element array, \f2x\fP, \f2y\fP, and \f2z\fP; and of a four-element array, \f2x\fP, \f2y\fP, \f2z\fP, and \f2w\fP. .SH DESCRIPTION \%\f3glVertex\fP commands are used within \%\f3glBegin\fP/\%\f3glEnd\fP pairs to specify point, line, and polygon vertices. The current color, normal, and texture coordinates are associated with the vertex when \%\f3glVertex\fP is called. .P When only \f2x\fP and \f2y\fP are specified, \f2z\fP defaults to 0 and \f2w\fP defaults to 1. When \f2x, y,\fP and \f2z\fP are specified, \f2w\fP defaults to 1. .SH NOTES Invoking \%\f3glVertex\fP outside of a \%\f3glBegin\fP/\%\f3glEnd\fP pair results in undefined behavior. .SH SEE ALSO \%\f3glBegin\fP, \%\f3glCallList\fP, \%\f3glColor\fP, \%\f3glEdgeFlag\fP, \%\f3glEvalCoord\fP, \%\f3glIndex\fP, \%\f3glMaterial\fP, .br \%\f3glNormal\fP, \%\f3glRect\fP, \%\f3glTexCoord\fP, \%\f3glVertexPointer\fP
