I think it is not just about what is expected. There is an emotive
juxtaposition. The water is beautiful with clear, aqua, tints
attractive to the eye, but still, it is utterly indifferent to the
sinking boat it envelops,...envelops with barely a shrug. A hueless,
pasty countenance for the water would produce a different result.
Repellent, awful, opaque. You would need a greater sense of mayhem and
drama surrounding the boat as it goes under. Right now the waves are
like the claws of a beautiful cat when it suddenly betrays its feral nature.
You picture is an astounding technical advance, in direct line from that
original piece by Alberto, that showed us the astonishing potential of
isosurfaces. But there is something to your title too. You signal
"artistic", probably in the sense of "stylized". And I think it is
true. Stylizations, are always to some degree, a meditation on the
effect of stylization. Van Gogh paintings for instance.
I have always loved marine paintings, and I never cared a hoot about the
boat. The boat is rarely more than an excuse to do water. And how a
particular painter stylized his water is always the fascinating thing.
For a stylization it must be, because water is never still for even a
moment. Even the airborne, gobbing, foam caught in a stop-action photo
of a crashing wave is not water as the human eye sees it. So an artist
must sneak up on the reality of water. It is often a matter of focusing
on one of the aspects of water, perhaps its solidity is emphasized, or
its transparency, its power, its motion, or its turbulence. Often there
is an attempt to understand its turbulent mayhem according to more
regular patterns. The focus on one representative aspect of the subject
allows for coherency and homogeneity within the limits of the technique
used. If this one aspect is observed and translated correctly the
portrayal is believed. Necessarily these attempts push the limits of
the available tool. Painters employ the effects of paint application:
measured strokes of brush, impastoed workings of the knife, delicately
laid in tints, splatters, or wiped back effects of the rag. With water,
tromp l'oeil is really not possible, (except perhaps with animation,)
for a still picture of water is automatically artificial. With the
painting of water we have always accepted the role of stylization, in
the sense of a knowing exploitation of paint application, together with
the judicious focusing of observation, in the artist's attempt to sneak
up on realism.
Raytracing, has been dominated by the technical hunt. It is a hunt based
in the paradigm of the subject-first-modeled-then-viewed, and it has
mostly allowed stylization only where the separation from realism is
clear and safe. It is acceptable, for instance, with animated cartoons,
which emphasize gesture, or perhaps with alien landscapes or beast-like
figures, where what is "real" is a hybrid fantasy anyway. Your picture
approaches a queasier area where tromp l'oeil results are sometimes
possible. A liquid surface rippled by concentric, even interfering,
sine waves can be modeled directly, while the turbulated patterns of
tree bark can only be simulated. Simulated closely, albeit, close
enough for tromp l'oeil even, but within the result there lurks the
conceptual tripwire that it is not exact, that what we relegate to
randomness may yet be a form we do not recognize.
Your portrayal of water, here, flirts with a difficult progression. The
transparency has a tromp l'oeil result. Same with the fractal peaking of
wavelets and dissolving foam textures especially in select areas. The
longer roll of crests and troughs is believable. But the steepening
crests topped with foam are a harder sell. And yet they are the main
attraction. They are also the most difficult to observe and remember
from real experience. They have a conceptual presence in our minds
which can be quite tangible but which may differ markedly from their
appearance in reality. The reality is motion, not stopped motion.
Steep waves "heave", "build", "boil", "churn", "break", "pitch", "roll",
"burst", "topple", etc. The look of this as stopped action is a
construct. Your picture asks us to suspend our personal concepts, and
accept your synthesis of how this might look. We must abandon the hope
of complete illusion while integrating its partial successes with the
more speculative parts of you synthesis. Is this the new "stylized"?
Can we accept the "artistic" outcome even as we relish the technical
underpinnings. Can we make the small step which substitutes fractal for
wave, and enjoy the real illusion of transparent liquid, even as we are
aware that we are doing both? I think I can.
