   Modeling a Ship in Alias|Wavefront's Maya 2.0

   By Carsten Lind

           thing to do
           modeling is
           to do research.
           I searched the
           web and found
           images of
           cruise ships. If
           you don't do
           the research,
           you might miss
           things that will
           make the

           After studying
           the images of
           the cruise
           ships carefully,
           I roughly
           sketched the
           basic shape of
           the ship in
           Maya using
           curves. These
           curves will then
           serve as a
           guideline when
           modeling the
                            Figure 1
           ship. I also
           applied all the
           curves to their
           own layer, so I

           own layer, so I
           can turn them
           all off at once
           evaluating the
           model. The hull
           of the ship was
           made by using
           Maya's birail
           function to
           sweep curves
           along two rail
           curves to get
           one side of the
           hull. The hull
           surface was
           then mirrored
           to get the
           complete hull.
           (Figure 1)

           I then build the
           front deck, by
           lofting the top
           curves from the
           hull. The
           cabin decks
           were then
           created by                                                          Employment

           was created
           from left side
           hull to the right
           side hull. I
           inserted a
           cylinder as a
           banister and
           duplicated it,
           running inside
           the lower deck
           side, to get
           some easy,
           yet effective
           detail on the
           lower deck.
           The chimney
           was created
           from a couple
           of lofted
           curves. The
           bridge is an
           extrusion of a
           shaped curve
           along one
           isoparm taken
           from the front
           of the upper
           cabin decks. I
           added a few
           serving as
           antennas and

           I also placed a
           few boxes and
           randomly on
           the surfaces to
           get the kind of

           on the ship.

           randomness to

           Always take a
           look at your
           material and
           take notice of
           the little things
           such as small
           boxes, and
           litter and used Figure 4
           sodacans and
           add those to
           get more
           realism into
           your model.

           I rendered an
           image of the
           ship from the
           side viewport in
           a large
           and opened the

           image in
           Photoshop. I
           made a layer
           and started to
           paint the
           ( Figure 4)

           This is the final
           texture that
           was assigned
           as a planar
           projection as a
           color map.
           (Figure 5)        Figure 5

           When creating
           the texture,
           make sure that
           the texture is
           cropped to fit
           the bounds of
           the ship -- this
           makes the
           alignment of
           the texture a
           lot easier in
           Maya. Just
           press the 'Fit
           to bounding
           box' button in
           the attribute
           editor on the

           method will be
           used for the

           I created the
           bump map for
           the windows

           the windows
           from the same Figure 7
           file I used for
           the colored
           texture. This is
           the greyscale
           bump map file.
           (Figure 7)

           I connected the
           bump to the
           network and
           reused as
           many of the
           network nodes
           as possible.

           Here you can
           see the
           network for the

           image with the
           bump map
           (Figure 9) I
           find it very
           important not
           to exaggerate
           bump maps.
           This is a
           common error
           made by quite
           a few artists.
           The bump map
           was adjusted
           using IPR
           which enables
           you to see     Figure 9

           Slowly, more
           and more
           textures are
           being applied.
           (Figure 10)
           The chimney
           now has a
           decal and the
           front deck now
           has a wooden
           texture applied
           (it's going to be
           though). I am
           going to place
           some railings
           on the edges of
           the decks and
           behind the        Figure 10
           chimney there
           will be a pool.
           But more on
           this later.

           This image
           was created to
           present the
           model for the
           client. (Figure
           11) It had to
           indicate that
           the ship was
           and I added the

           curve and
           lofted a surface
           between them.

           with the        Figure 12
           surfaces of the

           The texture for
           the bridge of
           the ship was
           all made in
           Maya. As you
           can see in this
           image of the
           network, it
           required quite a
           few nodes.

           of the texturing

           Just for the fun
           of it, I added
           the sea, and
           applied a sea
           shader I
           already had,
           just to see how
           it looked. I
           don't know who
           made this sea
           shader, but it's
           great! (Figure

           15)                 Figure 15
           First of all, I
           wanted to have
           the windows as
           a color map.
           For this I used
           the grid texture
           which was
           applied to the
           color node.

           Then I
           duplicated the
           grid node
           network and
           applied it to the
           connection on
           the shader.
           This gave my
           shader a
           brighter look on
           the white parts
           on the

           Finally, I
           created an
           sky node and
           connected it to
           the black color
           of the
           grid node to
           get a kind of
           reflection of a
           sky on the      Figure 16
           black parts of
           the windows.

           You can

           shader in the
           section here at

           The water level
           was adjusted a
           little and the

           applied a little
           Notice how the
           water surface
           reflects slightly
           on the hull. I
           also added
