<hr><a name="_details"></a><h2>Detailed Description</h2>
An abstraction of a viewport, i.e.
<p>
a rendering region on a render target. <dl compact><dt><b>
Remarks: </b><dd>
A viewport is the meeting of a camera and a rendering surface - the camera renders the scene from a viewpoint, and places its results into some subset of a rendering target, which may be the whole surface or just a part of the surface. Each viewport has a single camera as source and a single target as destination. A camera only has 1 viewport, but a render target may have several. A viewport also has a Z-order, i.e. if there is more than one viewport on a single render target and they overlap, one must obscure the other in some predetermined way. </dl>

If you expecting every pixel on the viewport to be redrawn every frame, you can save a little time by not clearing the viewport before every frame. Do so by passing 'false' to this method (the default is to clear every frame). </dl>

<a class="el" href="classOgre_1_1Overlay.html">Overlay</a> objects are layers which appear on top of the scene.

However, you probably don't want this if you're using multiple viewports, because one of them is probably a picture-in-picture which is not supposed to have overlays of it's own.
