Actually aoi-like images can be done with the slope pattern in regular 3.5:

#include "functions.inc"
#declare cam_location=-z*5;
#declare cam_lookat=<0,0,0>;
camera {location  cam_location look_at cam_lookat}
isosurface{
    function{f_sphere(x,y,z,1)-f_noise3d(x*2,y*2,z*2)*1}
    contained_by{sphere{0,2}}
    max_gradient 3.141
    texture {
        pigment {
            slope {cam_lookat-cam_location,0.6}
            color_map{[0 rgb z*2][1 rgbft 0]}
        }
        finish {ambient 1}
    }
}
