Various rendering choices? -- Challenge!

Martin,

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

But it remains a difficult exercise I guess

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.

A couple or tries with IRendernXt

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.

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).

KarinaGM

Wow! I love it. What are the settings for this material? and what material is this?
Lights?

TaffGoch

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):

(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.)

notareal

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).

Gaieus

There are some other, interesting layers in there...

Anssi

A first quick one with ArtLantis. 20 seconds.

I smell a render challenge....
Frigging cool model, curious how it was made.

Your wish is granted...

I included hidden layers in the model, to demonstrate the development of the sinusoidal "Follow me" path. The methods are conceptually simple, and radial symmetries permit copies of components, so it's not as complex as it first appears.

BTW, you may consider yourself challenged....
