    <h2>About this sample</h2>
    <p>
      This sample tests containment and intersection between animated triangles, spheres and boxes
      and five primary shapes: a sphere, ray, viewing frustum, axis-aligned box and oriented box.
      Most primary shapes have white outlines, while the ray is red. Moving shapes turn red
      when contained, yellow when intersecting and light gray when disjoint.
    </p>
    <p>
      Switch groups to see each collision pairing. The camera can rotate, zoom and change between
      perspective and orthographic projection; the simulation can also be paused and stepped.
    </p>
