<p>I started at Digital Domain as a software engineer. I then decided
to become a Digital Artist, but it looks like I am drifting back to
software again, just for old times sake. I am the original author of
<a href=/Departments/soft/Documentation/Nuke>Nuke</a>, the Digital
Domain in-house compositing program.
<p><img src=TD27_FINAL.0100.jpg>
<br>I also spent a lot of time making this water.
<p>For clarification, a lot of other people worked on this water too!
Perhaps as many as 50 or 60!
<p>Contrary to popular belief, <i>the ship is not CG</i>. It is a
miniature, 1/20 scale (about 45 feet long), and easily the most
detailed model of the Titanic ever made. It was produced by the
Digital Domain model shop, with many outside contractors (1/8 scale
and 1/4 scale sections of the ship were also produced for filming in
real water). This model survives, and will be on permanent display
<i>somewhere</i>, though noone seems to know where as of yet.
<p>The people on the ship, the water, the smoke and steam,
the seagulls, and some of the rigging is CG. They are rendered
with Pixar's RenderMan. The people were modelled and animated using
SoftImage, the other items with Side Effects's Prisms. The sky is a
painted photograph, run through "pan and tile" to pan with the scene.
<p>The water is produced using Arete's RenderWorld software, with many
modifications that I worked on with them to add reflections and
texture mapping to the surface. The "foam" is live action footage
shot from straight overhead of the Lane Victory, a WWII victory ship.
These images were scaled and duplicated several times to adjust for
the fact that the Titanic was three times faster and twice as long,
and texture-mapped onto the water surface. The spray against the ship
is a Prisms particle system, enhanced sometimes (though not in this
shot) with live action shot with high-pressure hoses in a swimming
pool.
<p>Though not used in this shot or other "hero" shots, the Titanic was
modelled and rendered using LightWave for "set extensions", in
particular to make the hull below the full-size set. LightWave was
also used to produce a very detailed and accurate "simulation" of the
Titanic sinking, unfortunately only a small portion of this simulation
is seen in the final cut.
