<h2 id="details">Detailed Description</h2>
<p>The <a href="qt3drender-qlevelofdetail.html">QLevelOfDetail</a> class provides a way of controlling the complexity of rendered entities based on their size on the screen.</p>
<p><a href="qt3drender-qlevelofdetail.html">QLevelOfDetail</a> can be used to control the representation of an entity based on distance from the observer or size on the screen.</p>
<p>In order to improve rendering performance, objects that are very small can be rendered using far fewer details, in geometry or texture.</p>
<p>The component is controlled by specifying thresholds of values which are interpreted as either distances from the camera or screen size.</p>
<p>As the point of view changes, the <a href="qt3drender-qlevelofdetail.html#currentIndex-prop">currentIndex</a> property will change to reflect matching value in the range array.</p>
<p>The <a href="qt3drender-qlevelofdetail.html#currentIndex-prop">currentIndex</a> property can then be used, for example, to enable or disable entities, change material, etc.</p>
<p>The <a href="qml-qt3d-render-levelofdetail.html">LevelOfDetail</a> component is not shareable between multiple <a href="qml-qt3d-core-entity.html">entities</a>.</p>
