John Donivan,
I am sorry, but this is going to be a long winded response. I fell
there is too much to say for a single paragraph. First, let me
explain what I’m about: In addition to wholesale custom work for
others (finished jewelry objects which mostly sell in the thousands
of dollars price range), I create my own one of a kind jewelry and
have been since I started out as a college jewelry/art student back
in 1975. I enjoy design evolution either on paper, as I work with
metal or wax, and now (since 2001) in 3D on the computer.
There's jewelry drawings, and then there's jewelry....
If someone wants to do a Jewelry Rendering Competition.... that's
fine, but it won't be a jewelry design competition.
The key word here is “Design” I have seen a number of “design”
competitions for jewelry over the years where the deign rendering
itself was the object which was being judged. Most of those
competitions stipulate that the design must be capable of being built
into a “real” object. Some also stipulate the winners must actually
finish the design in metal usually within a specified period of time
to display the finished object in a show. I agree with you that,
while M.C. Escher is a wonderfully fanciful designer, most of his
designs would have failed to place in this kind of competition; lest
he were to do them as 2-1/2D “paintings” on metal. [though his mobius
strip can be created in real life (I’ve had to do a couple of
projects based on the mobius concept for different jewelers over the
years).]
Keep in mind, these competitions are design
(drawing/rendering/creativity/skill at imagining a producable
object) competition, not a jewelry making competition
(aside: competition for what?)
First see my above response. Secondly, there should be a place for
jewelry design competition (with fanciful or finishable jewelry as
the subject) in the jeweler’s community (both hand drawn and
computer rendered) to demonstrate and challenge the artistic skill of
the competitors, just as there are for other forms of still life
painting/drawing. As for “CNC” (which is more properly
“CAD”-Computer Aided Design); there can be as much “art” involved in
using CAD-Rendering as there is in using colored pencils and paper.
To create a good rendering of a virtual object the user needs to have
knowledge of light’s multiple characteristcs (light pathing,
reflection, refraction, intensity, color, shadowing, etc.)
controlling surface juxtaposition and composition as in any method
of painting or drawing. If you could give a number of people the same
computer created jewelry file (with no rendering attributes in the
file) and have them render it with their favorite rendering
programs, you would get as many different results as you had
competitors, not only because the programs differ, but more
importantly because the users’ knowledge of what attributes of the
“drawing” it takes to make a flat 2D picture appear as if it jumps
off the page in 3D “realism”.
From the post you responded to:
If it really doesn't exist beyond someone's screen, it ain't
jewellery. The real challenge is in the accuracy of the
realization, not the design.
These are two totally different “real challenges”: jewelry design
and jewelry making skills. The argument could be used with respect to
jewelry drawings/paintings on paper or canvas vs a realized jewelry
object; if you were prone to that viewpoint. The argument is about
apples and oranges, in my opinion, though. Bad and good jewelry
design/realization can happen in all techniques used to create the
design; bad and good finished pieces can happen wheter started on a
computer or on paper.
With practice, the 3D computer programs can drastically reduce or
eliminate the amount of design errors in a piece compared to the
traditional methods of design. This is true because you are able to
observe a design in any direction by rotating it on screen as if it
were in your fingers, you can zoom in even further than you could
with a standard bench microscope, you can look inside at an unexposed
area (where in real life it would be blocked from view by other
components laying in the line of sight). You can measure every
portion of your design with as much accuracy as ever necessary ( in
Rhino that is out to the 7th decimal of a millimeter). And then, if
problems or visual dislikes are found, you are able to make changes
before you actually build a model. As with any design process, the
real challenge of computer-aided-designing is in creating a virtual
model which CAN be turned into reality, with no flaws or weak areas,
impossible stone settings, and, most of all, an object which is
visually pleasing and/or artistcally compelling in some way to most
people. I’m not saying that bad design doesn’t occur using CAD, but
that VERY good design is VERY possible. That is The First Challenge.
From there, The Second Challenge: the designer, if she/he is also
the jewelry maker, (and both John and I know that isn’t always the
case) must perform well with her/his metal/setting skills in order to
bring the jewelry object to full fruition with finese (to bring it to
life, as it were); just as it happens going from paper and pencil
design to finished jewelry. Once the virtual object checks out to be
valid in all realms, on the computer screen (as it would need to on
paper, if you choose to hand draw the design) and by way of the
designers’ knowledge of what comprises good design, it can then be
machined or printed on any number of the available stereolithograhy
machines, merely by-passing the hand carving steps. If the machine
work was done in wax the maker will then cast/ fabricate/texturing in
some cases, finish and perform all other “normal” jewelry procedures
required to complete a computer designed model; just like as if it
had been a hand carved wax. If the file were machined in metal, there
is still finishing work, fabrication and the like to complete. To do
all of these steps at the quality level that discerning clients
demand is totally dependant on the skills of the craftsman
completeing the work done on the computer. This is The Second
Challenge
To produce quality jewelry that is both well crafted and visually
pleasing is a never ending series of challenges and is (should be)
the ultimate goal of all jewelry makers, no matter the techniques
that the designers/makers choose to use; no matter if the goal is
“art” or wearable jewelry; no matter if we make for our own sake or
for others; as has been put forth on this forum many times past.

PS, John:
How many renderings have I returned for redraw because they just
could not be done in metal
As do you, I build the jewelry designs which other jewelers create
on paper or on the computer; and I have to agree with you that there
are times I need to discuss with my client artists why their
creations don’t hold up in 3D or as a viable piece of jewelry because
of some weak areas, risky or impossible setting design, you name it.
I don’t think I would say I’ve had to return an inordinate number of
renderings to be corrected, but I’ve had my share of discussions with
the artsists I have worked for as to what changes would need to be
made to make their ideas happen in reality. That’s a big part of this
area we’ve chosen to make our living in; as frustrating as it can
sometimes be.
