Various rendering choices? -- Challenge!

remon_v

Octane render (Geforce 470) 10:01, but I don't see the difference after 5 min.:

I haven't really played with Octane that much yet, but it's fast

remon_v

I left it for 20:01 min now:

I do see the difference

Great model - I imagine we'll see it turn up as an ornament in many interior renders, or even as a piece of garden sculpture.

I think it's already popping up

i did one for fun here. Looks like candy.

Yum!

I like the variations produced by transparent materials, having a moderate internal index-of-refraction,...

...and really shiny materials with all the "self" reflections (like those in the renders posted by remon_v.)

Hieru,

Soccer? Really?

...sepak takraw, maybe...

...but, soccer ??

I thought they both looked rather surprised

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 ? "

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

A couple or tries with IRendernXt

An exercise: DRAWING A PARISIAN FENCE

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

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.

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.

pyroluna

I had a little try in Shaderlight... did need some postpro afterwards, but not much.

notareal

Here is something from Thea. Tried global medium and a single light.

Taff also "maintains" a very interesting discussion group about the staff.

Tried playing with the new Thea Thin Film, interesting but only partially successful.

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.)

Really nice Pentti!

notareal

Here is another try (again pure render from Thea).
