<h2 id="details">Detailed Description</h2>
<p>The 3D scene contains a single active camera and a single active light source. Visualized data is assumed to be at a fixed location.</p>
<p>The 3D scene also keeps track of the viewport in which visualization rendering is done, the primary subviewport inside the viewport where the main 3D data visualization view resides and the secondary subviewport where the 2D sliced view of the data resides.</p>
<p>Also the scene has flag for tracking if the secondary 2D slicing view is currently active or not.</p>
<p><b>Note: </b>Not all visualizations support the secondary 2D slicing view.</p><!-- @@@Scene3D -->
