<!-- $$$BlitFramebuffer-description -->
<a name="details"></a>
<h2 id="details">Detailed Description</h2>
<p>This node inserts a <code>glBlitFrameBuffer</code> or an equivalent into the command stream. This provides a more efficient method for copying rectangles between textures or surface backbuffers wrapped by QRenderTarget than drawing textured quads. It also supports scaling with the specified interpolation method.</p>
<p><b>Note: </b>In practice the <a href="qml-qt3d-render-blitframebuffer.html">BlitFramebuffer</a> node will often be used in combination with <a href="qml-qt3d-render-nodraw.html">NoDraw</a> since a blit should not involve issuing draw calls for any entities.</p><!-- @@@BlitFramebuffer -->
