      Hi Guys,

      %(#0000FF)[Sorry for disturbing with my digression (no render in the pocket 😳 )]
      First I have searched to know what notion was covering " a geodesic"! " A geodesic is a generalization of the notion of a "straight line" to "curved spaces". In the presence of a metric, geodesics are defined to be (locally) the shortest path between points in the space." (may be better explain in the french wiki 😉 )

      👍

      Your drawing dear Taff Gosh (Taff: The Trans-Atlantic Fan Fund, also known as TAFF, was created in 1953 for the purpose of providing funds to bring well-known and popular members of science fiction fandom familiar to fans on both sides of the ocean, across the Atlantic(>>3D Basecamp 2010!!!!!).Goch (archaic spelling: Gog) is a town in the district of Kleve, in North Rhine-Westphalia, Germany.

      Your drawing reminds me an exercise I wanted to suggest some month ago and had forgotten under the pile..

      this was: " HOW TO DRAW A PARISIAN FENCE ? "

      http://i274.photobucket.com/albums/jj245/Spendauballet/SketchUp/cloturetissee003.jpg

      In my mind the problem was "how to draw a sinusoid following the path of one element (component) and matching the good crossover at the various meeting points?"

      The solution you had applied to your geodesic weave sphere opens to me some idea to achieve this..
      -one element of answer is that each component goes with a neighbor mirrored one.

      But it remains a difficult exercise I guess 😒

            Good renders people, given it a try in Shaderlight for SketchUp

              Martin,

              I was shooting for "jade" last night (and missed.) What I got is similar to yours, in green, rather than red.

                Simon,

                Tedious, yes! -- Difficult, not so much.

                Technically, the concept is simple. Scaling the sine wave lengthwise, to fit each straight line segment, is all that's required (while keeping the wave height constant.) It just takes some time to do each segment. If you need another example, here's a "flat" weave that employs the same technique:

                Rope • Cornish Wheel Knot

                http://sketchup.google.com/3dwarehouse/download?mid=38f95256a00b460f2137e32e8ebf2b1&rtyp=lt&ctyp=other&ts=1276476025000

                Construction
                If it had not been for the radial symmetries in both of the weave models, I would not have attempted them. With symmetries and component-copying, the modeling becomes (almost) trivial. Actually, the flat weave was more troubling than the sphere!

                  that will look nice on my Christmas tree this year.

                  If I make it look easy...It is probably easy

                    Richard, I like the dark carbon-tinted version. Again, it's the complex reflections that produce the visual interest -- all other features (distractions) removed.

                    It's like comparing b&w to color photography. Shadows and reflections take precedence. Nice exercise.

                              The internal mirror globe (Pyroluna) and the internal lighting (notareal) introduce enchanting complexities to the renders.

                              (I especially like the "God rays" produced by the "fog" in notareal's render.)

                                      notareal,
                                      I'm also intrigued by your Thea transparent material for your latest.

                                      Is this material available for download (here or at Kerky website.) ?


                                      Here's my latest (slowly improving) attempt at jade (still using Photoshop adjustments):

                                      http://i579.photobucket.com/albums/ss233/taffgoch/Jade_small.jpg

                                      (I'm testing only material changes, to get accustomed to the materials editor parameters in Kerkythea. I'll move on to lighting & environment, after I'm more comfortable with materials.)

                                        Sorry, unfortunatelly Thea materials cannot be used in KT, material systems are that different. Thea can do a conversion of KT materials, but as it does use heuristic, one might need to tune up imported complex KT materials.
                                        But to the render... The material uses thin film interference for color and fairly simple studio with HDR. You can find full Thea scene here (Note: need to use Thea RV378 or later).
