<H3>Summary:</H3>

<BLOCKQUOTE>
|

|
|
The <B>level</B> command sets the rendering level to <I>n</I>,
|
||
|
|
if given, or else returns the current rendering level.
|
||
|
|
There are two rendering levels in this implementation.
|
||
|
|
Rendering level 1 (one) uses OpenGL line and polygon
|
||
|
|
antialiasing. Rendering level 0 (zero) does not use
|
||
|
|
antialiasing, so yields a coarser but faster rendering.
|
||
|
|
The wish-list for the future includes higher rendering
|
||
|
|
levels to represent rounded edges on wells and diffusion,
|
||
|
|
and a more accurate vertical profile.

<H3>Implementation Notes:</H3>
|
||
|
|
<BLOCKQUOTE>
|
||
|
|
<B>level</B> is implemented as a built-in <B>wind3d</B>
|
||
|
|
window command in <B>magic</B>. It can only be invoked from
|
||
|
|
a window created with the <B>specialopen wind3d</B> command,
|
||
|
|
or the <B>render</B> procedure. 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>".
