PovRay 3.5: Torus Bugs? Predefined Torus different from Isosurface Torus

Isosurface Code:

isosurface {
function { f_torus (x,y,z,0.385, 0.37) }
        accuracy 0.001
        threshold 0
        max_gradient 4
contained_by{sphere {0,0.5}}
texture{pigment {White filter 0.7} finish{specular 1}}
}


Predefined Torus Code:

torus{0.385, 0.37}
texture{pigment {White filter 0.7} finish{specular 1}}

	Try increasing the radius to at least 0.755 (0.385+0.37).

In the future, you should include a more detailed description about what
you're seeing compared to what you expect to be seeing. That makes it easier
to diagnose the problem without digging through the source code. Thanks!
