With our SPIROS 3dsMax script you can intuitively create beautiful and precise custom spirals and helices for spline modeling and animation.
The image above shows a kind of glass sphere, surrounded and supported by a particular helical shape. This was made in 3dsmax, by joining 2 different spline shapes provided by Spiros: a loxodrome (special spherical helix) and a biased conical helix.
