<h2 class="description">Description</h2>
<div class="nodescription">no description available, TBaseTrianglesOctree description follows</div><p>
Abstract class for octrees that can check and return collisions with <a class="normal" href="X3DTriangles.TTriangle.html">TTriangle</a>.
<p>Octree node class used by this must be a <a class="normal" href="X3DTriangles.TBaseTrianglesOctreeNode.html">TBaseTrianglesOctreeNode</a> descendant.
<p>In a simple case, this is an ancestor of <a class="normal" href="CastleTriangleOctree.TTriangleOctree.html">TTriangleOctree</a>, that is just an octree storing <a class="normal" href="X3DTriangles.TTriangle.html">TTriangle</a>. But it's also an ancestor of <a class="normal" href="CastleShapeOctree.TShapeOctree.html">TShapeOctree</a>, since each shape has also a triangle octree. This way, <a class="normal" href="CastleShapeOctree.TShapeOctree.html">TShapeOctree</a> can calculate collisions with <a class="normal" href="X3DTriangles.TTriangle.html">TTriangle</a>, even though it doesn't directly store <a class="normal" href="X3DTriangles.TTriangle.html">TTriangle</a> items.</p>
