A bounding sphere.

Bounding spheres are very fast to intersect test, but they are fairly loose. If asked to choose just one bounding volume, four out of five graphics professionals surveyed chose the bounding sphere for their patients who chewed bounding volumes. <hr><h2>Constructor &amp; Destructor Documentation</h2>

Intersect this bvolume with a <a class="el" href="classopenvrml_1_1frustum.html" title="A view frustum.">frustum</a>. 
<p>
The test assumes that the <a class="el" href="classopenvrml_1_1frustum.html" title="A view frustum.">frustum</a> is in the canonical looking-down-negative-z orientation, so the bounding volume is going to have to be transformed into the frustum's space. (Alternatives include transforming the <a class="el" href="classopenvrml_1_1frustum.html" title="A view frustum.">frustum</a> into the bounding volume's space, or transforming both of them into the projection space. Lots of tradeoffs involved, but transforming the bounding volume is probably the simplest approach overall.)<p>
