<hr/><a name="details" id="details"></a><h2>Detailed Description</h2>
<div class="textblock"><p>Defines a 3-dimensional frustum.</p>
<p>A frustum in computer graphics is generally a volume of 3D space, defined as the part of a rectangular pyramid that lies between two planes perpendicular to its center line. A frustum is often used to represent what a "camera" sees in your 3D space.</p>
<p>The <a class="el" href="classgameplay_1_1_frustum.html">Frustum</a> class allows you to define a bounding frustum using a combined matrix that is generally the product of a view matrix and a projection matrix.</p>
<p>You can query a <a class="el" href="classgameplay_1_1_frustum.html">Frustum</a> object for any one of its bounding planes, for its corners, and for whether it intersects with a given object. Since objects that don't intersect with your view frustum generally don't need to be rendered, culling them quickly can save you a lot of rendering time. </p>
