      Hmm so much theory ..what i did was simple,make a spring,make a copy of it,take a spring and adjust it with ffd(remember to let the top and bottom points untouched) in order to make from it the inside part of the spiral, after this take the other one and flip it along in order to continue(descend on the outside) the first one,then play with ffd on it in order to make the exterior part of the spiral(remember to let the top and the bottom points untouched).Then i used lines to tube plugin. And that s kind of it!
      Ah..and before working them with ffd i flattened(with ffd) the top and bottom spires of the springs to make a smooth transition from a spire to another.

          @Ely,

          Hi Ely, I like your way: searching for simple and quick processes 😎 your solutions are refreshing 👍
          SketchyFFD (Free Form Deformation) is a good deal for sure 👍 👍

          Hi Taff (I have noticed you are from the early morning, and I'm waiting my own awakening to read your posts 😉 ) Thank you for your colored exemples. I guess the same treatment as you've done with your Geodesic Weave Ball should be also very great 😉

            More torus segments produce results that better approximate the original images.

              Simon,

              I tried the chipped-paint texture, but it was too "busy," and was a visual distraction.

              A simple texture looks good though, when rendered:

                Dear Taff,

                Simple is the best; it is a "réussite" . I see it in 2D, spirit relaxing.
                (But is it so simple? I mean about the discrete raw of light)

                'Cause you seem also from late in the night, I wish U a good one.

                  As I can understand the law of this:

                  1. the shape must make a number of entire 360° turns
                  2. the complet set of edges(included into the basic section) must be used a complete number of times.
                  3. the number of edges used in the number of complete turns must meet the number of edges constituting the basic section used to produce the spiral.

                  and
                  4)the number of entire 360° turns of the shape must be the minimum one (sorry for bad explanation. I think it is the meaning of :"Least common multiple" )
                  (It doesn't make sens for the basic shape to go around more than the necessary number!)

                    Simon,

                    I didn't pursue the precise defining of the calculations, but I sensed the general concept of the relationships.

                    When I started on my second model, I roughly estimated a "longitude-to-latitude" ratio that should (might) produce a more-complex, tighter spiral with less slope, and six loops.

                    As an intellectual pursuit, yours is a good mental exercise. (Perhaps, if it were mid-winter, and I was snowed-in, then I would have time to wrestle with a precise definition.) 😆

                              Looks like sketchup physics and a screen recorder(camstudio maybe).

                              Taff if u used Camstudio,please let me know ur settings ,i can t make it record that smoother.

                                    Simon & Elisei,

                                    I tried using Camstudio, initially, but the results were poor. Camstudio is easy, but doesn't always provide quality results. It's great, for what it is intended, but there is a better option for a "looped" animation of limited frames -- GIF animation software. (This animation is composed of only 15 frames.)

                                    I created the frames from SketchUp 2D exports, rotating the torus 2° each interval, producing 30° total rotation. (This matches the model component rotation of one spiral "tube" to the next.)

                                    I kept the SketchUp viewpoint constant, and rotated the torus, to avoid any camera positioning problems. I could have established 15 camera locations, to produce 15 scenes, but the way I did it was quicker. (Creating 15 camera/scene postions, however, does have the advantage that they can be saved in the model file, for subsequent use.)

                                    I assembled the 15 frames into a GIF animation, using JASC "Animation Shop," which I bought (cheap) over ten years ago. It's my understanding that COREL bought-out JASC. The older "Animation Shop" (vs 3) can be downloaded from several online sites, or you can use one of the MANY other freeware GIF animators, available online.

                                    [NOTE: I used the same technique to create my avatar.]

                                          I have made my own try with animation on this spiral cone . Dear Taff I don't know why I don't reach the smoothness of yours ~~

                                            Simon,

                                            The first and last frame appear to be the same, which looks like a pause, or stutter, in the animation. I deleted the last frame, and it's somewhat better:

                                            Edited
                                            However, now there's a slight "jump" in the animation. 😕 I can only guess that there must have been a variation in the degree-of-rotation for one of the frames.

                                            -Taff
