-     * Given an OpenGL ES ModelView-Projection matrix (which implicitly
-     * describes a frustum) and a list of spheres, determine which spheres
-     * intersect the frustum.
-     * <p>
-     * A ModelView-Projection matrix can be computed by multiplying the
-     * a Projection matrix by the a ModelView matrix (in that order.). There
-     * are several possible ways to obtain the current ModelView and
-     * Projection matrices. The most generally applicable way is to keep
-     * track of the current matrices in application code. If that is not
-     * convenient, there are two optional OpenGL ES extensions which may
-     * be used to read the current matrices from OpenGL ES:
-     * <ul>
-     * <li>GL10Ext.glQueryMatrixxOES
-     * <li>GL11.GL_MODELVIEW_MATRIX_FLOAT_AS_INT_BITS_OES and
-     * GL_PROJECTION_MATRIX_FLOAT_AS_INT_BITS_OES
-     * </ul>
-     * The problem with reading back the matrices is that your application
-     * will only work with devices that support the extension(s) that
-     * it uses.
-     * <p>
-     * A frustum is a six-sided truncated pyramid that defines the portion of
-     * world space that is visible in the view.
-     * <p>
-     * Spheres are described as four floating point values: x, y, z, and r, in
-     * world-space coordinates. R is the radius of the sphere.

-     *        data starts
-     * @param spheresCount the number of spheres to cull.
-     * @param results an integer array containing the indices of the spheres
-     * that are either contained entirely within or intersect the frustum.

-     *        start.
-     * @param resultsCapacity the number of array elements available for storing
-     *        results.
-     * @return the number of spheres that intersected the frustum. Can be
-     * larger than resultsCapacity, in which case only the first resultsCapacity
