ellipsoids.x3d

 (.x3d scene, pretty-print source, statistics, info & logs, X3DOM home)

Test multiple ellipsoids. The fields minBack, minFront, maxBack and maxFront are set to create a typical elongated inner and outer ellipsoid for a Sound node. As a result, a differential distance between inner and outer ellipsoids exists as one moves between the two. Viewpoints are set up along the X, Y and Z axes to test sound levels outside, between and inside ellipsoids. Text at the bottom of the world indicates what the expected sound volume should be for each Viewpoint.
