<h2><a name="intro">Introduction</a></h2>
|
|
|
|
Togl is a <a href="http://www.tcl.tk/">Tk</a> widget for
|
|
<a href="http://www.opengl.org/">OpenGL</a> rendering.
|
|
Togl was originally based on OGLTK, written by Benjamin Bederson at
|
|
the University of New Mexico.
|
|
|
|
Togl's main features are:
|
|
|
|
<ul>
|
|
<li>unifies Microsoft Windows, X11 (Linux/IRIX/...), and Mac OS X Aqua support
|
|
<li>support for requesting stencil, accumulation, alpha buffers, <i>etc</i>.
|
|
<li>multiple OpenGL drawing windows
|
|
<li>simple stereo rendering support
|
|
<li>simple, portable font support
|
|
<li>color-index mode support including color allocation functions
|
|
<li>overlay plane support
|
|
<li>OpenGL extension testing from Tcl
|
|
<li>Tcl Extension Architecture (TEA) 3 compliant
|
|
</ul>
|
|
|
|
<p>
|
|
Togl does almost no OpenGL drawing itself,
|
|
instead it manages OpenGL drawing by calling various Tcl commands
|
|
(<i>a.k.a.</i>, callback functions).
|
|
Those commands can be C functions that call OpenGL (in)directly
|
|
or another Tcl package
|
|
(<i>e.g.</i>, <a href="http://www.tcl3d.org/">Tcl3D</a>).

<h2><a name="bugs">Reporting Bugs</a></h2>
|
|
|
|
<p>
|
|
There is a bug database on the
|
|
<a href="http://sourceforge.net/projects/togl/">Togl Project Page</a>.
|
|
You may also discuss bugs on the mailing list.
|
|
<p>
|
|
It may be worth upgrading your graphics driver and retesting
|
|
before reporting a bug,
|
|
as, historically,
|
|
many Togl "bugs" have been fixed by a graphics driver upgrade,
|
|
especially on Microsoft Windows.
|
|
<p>
|
|
When reporting bugs please provide as much information as possible.
|
|
Such as the version of Togl, which operating system
|
|
(<i>e,g.</i>, Microsoft Windows, Red Hat Linux, Mac OS X, <i>etc.</i>),
|
|
the version of the operating system,
|
|
and the version of the graphics driver.
|
|
Also, it's very helpful to us if you can provide an example program
|
|
which demonstrates the problem.
