Dancers Pendant: Matthias Pfoetscher, Tirol, Austria

Prize: Matrix 7, 3D print of model in photosilver courtesy envisionTEC, T-Splines T-Shirt.

Designer quote:

I made this dancers pendant as a tribute to one of my favourite painters Liliana Rago. I once had the luck to find an exhibition of her work on the island of Corse and I got hooked on her art ever since.

I started this design by building a very simple body shape from scratch, starting with the torus and attaching legs, arms and head. I then arranged the feet and arms so that they would show the motion of dance. All of this was followed by extensive pushing and pulling.

The torus was started from a basic line I drew in rhino and then extruded. I extruded legs and arms from the closed torus. The head and woman's chest were made from the quadball primitive.

I first modeled the woman then the man. I did not attach hands at first but did it in the end when I knew the final position of the two models. The last important t-splines part was the woman's dress which i chose to model seperately because I wanted to follow an approach that is more realistic.

I originally wanted the pendant to be more 2D and wanted to model it in 3D and than flatten it from the best angle. But in the end I thought that fully plastic shape is also nice.

All basic T-Splines stuff was made in plain Rhino 4 with the latest T-Splines version. I do have access to Matrix 6.3 but using T-Splines in there can cause more problems than in plain Rhino.

To make it jewelry I used Matrix and the gem on surface command which works directly with t-splines when in slow (exact?) mode.

The arc and the bail were made in T-Splines as well.

For the chain I used object on curve and a segment of the ""Beavco chain pack"" by Matt Bennett.

For rendering I used the V-Ray Lite that comes with Matrix. Unfortunately, I can only render in resolutions up to 1280px on one side.

One thing I always had in mind when modeling this piece was that it should always stay producable. My approach in producing this model would be to RP it with a grower in 6 parts:

- woman

- man

- 2x hairdo

- arc

- bail

The only thing that I would probably not do would be to make the dress seperate and therefore in another metal color like on the renders. I would probably just boolean it together and grow as one part.

T-Splines was a really cool tool to model this piece. Everybody who does NURBS modeling sees that it just cannot be done in NURBS. I don't know if another software like Z-Brush would work better but I got the result I wanted with T-Splines.

In the end it still took me about 30 hours from start to finish which is a lot. It would be probably still be too much for an ordered custom job which is what I do most.

Regarding the contest theme: I personally have thought a long time how jewelry can make the world a better place and came up with the answer that it always does. Making people happy is still the best part about jewelry and especially custom made designed for one specific person does really affect people. T-Splines helps us to do just that!

This is the first contest I ever participated and I'm still a novice on many levels. It was a lot of fun though and I'm very curious about all the great designs we will be able to see very soon.

Thank you for creating this contest and to all the sponsors.

Judges quote:

Great use of T-Splines over traditional Nurbs modeling. A very whimsical theme and fun piece of jewelry.

This model had all the overall qualities for the contest: manufacturability, aesthetics, use of T-Splines, clean geometry and as far as theme, if more people danced, the world would indeed be a better place.
