<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.

<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>".
