<hr/><a name="_details"></a><h2>Detailed Description</h2>
<p>An ImposterSprite is a textured quad which is rendered in place of 3D geometry. </p>
<p>The ImposterSprite is generated by rendering the original 3D geometry to a texture as an image cache. The <a class="el" href="a00364.html" title="An ImposterSprite is a textured quad which is rendered in place of 3D geometry.">ImpostorSprite</a> is automatically generated by the <a class="el" href="a00182.html" title="Basic NodeVisitor implementation for rendering a scene.">osgUtil::CullVisitor</a> so it not necessary to deal with it directly. </p>
