Specify the 3D viewpoint position
<HR>
scroll [x y z]
<H3>Shortcuts:</H3>
<BLOCKQUOTE>
The <B>arrow</B> keys implement different aspects of the <B>scroll</B>
command, panning in the <I>x</I> and <I>y</I> directions relative to
the normal layout view.
</BLOCKQUOTE>
<H3>Usage:</H3>
<BLOCKQUOTE>
<B>scroll</B> [<I>x y z</I>] <BR><BR>
<BLOCKQUOTE>
where <I>x</I>, <I>y</I>, and <I>z</I> represent the viewpoint
position in each of the axes.
</BLOCKQUOTE>
</BLOCKQUOTE>
<H3>Summary:</H3>
<BLOCKQUOTE>
The <B>scroll</B> command sets the 3D viewpoint position on
each of the axes, where the <I>x</I> and <I>y</I> origins are
equal to the layout origin, and the <I>z</I> origin is on the
substrate. Without arguments, returns the current viewpoint
position in the three axes.
</BLOCKQUOTE>
<H3>Implementation Notes:</H3>
<BLOCKQUOTE>
<B>scroll</B> is implemented as a built-in <B>wind3d</B>
window command in <B>magic</B>. It overrides the default
window client <B>scroll</B> command. Note that the <B>wind3d</B>
window is only available when magic is compiled with the OpenGL
graphics option and invoked with <B>magic -d OGL</B>. <P>
Note that macros of the <B>wind3d</B> window are hard-coded,
and cannot be changed with the <B>macro</B>, <B>gmacro</B>, or
<B>imacro</B> commands. There is no "<TT>:</TT>" macro for
entering commands; to enter commands from the command-line,
use the <A HREF=../tk_path_name.html> <I>tk_path_name</I></A>
command. The default Tk path name of the <B>wind3d</B> window
is "<TT>.magic3d</TT>".
