subroutine xfpts(x, y, z)
integer*2 x, y, z

subroutine xfpt2(x, y)
real x, y

subroutine xfpt2i(x, y)
integer*4 x, y

subroutine xfpt2s(x, y)
integer*2 x, y

subroutine xfpt4(x, y, z, w)
real x, y, z, w

subroutine xfpt4i(x, y, z, w)
integer*4 x, y, z, w

subroutine xfpt4s(x, y, z, w)

Pascal
procedure xfpt(x, y, z: Coord);

procedure xfpti(x, y, z: Icoord);

procedure xfpts(x, y, z: Scoord);

procedure xfpt2(x, y: Coord);

procedure xfpt2i(x, y: Icoord);

procedure xfpt2s(x, y: Scoord);

procedure xfpt4(x, y, z, w: Coord);

procedure xfpt4i(x, y, z, w: Icoord);

procedure xfpt4s(x, y, z, w: Scoord);

DESCRIPTION

xfpt multiplies the specified point by the top matrix on the matrix stack and turns off the clippers and scalers in the Geometry Pipeline.  In feedback mode, the 4-dimensional result of the multiplication is saved in the feedback buffer.  In non-feedback mode, the command is ignored. 

NOTE

This command can be used only in immediate mode.
