<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Yes, you don't need OSMesa when there is graphics hardware support. In that case though it will still pop up a render window to create screen shots. OSMesa can still be used even if you have graphics hardware support and is currently the only way to get around having a window to render into.<div>

WriteAnimation() needs to create a window in order to generate the image. It is the same with WriteImage().<br>
