IMAGE DESCRIPTION: 
  My fiancee thought of the 'ship-in-a-bottle' idea.  So I took that
and thought of the environment it would be in.  Of course there had
to be some glass objects around it.  


DESCRIPTION OF HOW THIS IMAGE WAS CREATED: 
  The first object I made was the bottle.  I created this with Rhino.
Rhino is a NURBS based modeller that is currently in public beta (the
final product will be around 800 dollars (US) maybe my math skills will
be up to making a free NURBS based modeller :-).  Anyway I drew the outline
and made a Surface of revolution out of it.  I then made a simple cork
to go into it using a SurfORev.  The bottle has an indentation on the
bottom of it and a bulge in the middle.
  Then I went and made the 'glass'.  I think I did fairly good with it.
There is a little lip on the rim of the glass and the bottom is tapered
with a curve in it.  Also in the center of the glass at the bottom
is that point that makes glasses look like they were made on a lathe :-).
  After that I had to make something that spilled out of the glass
so I made the ice cubes.  They are the kind that you find in automatic
ice makers.  Then I 'melted' one by csg subtracting part of it and
took a chunk out of the other one.
  Glasses seemed a natural extension to the scene and so I went to work
on those next.  I drew the outline of the lenses then extruded that to
make a solid.  However that made flat lenses.  So I took really big
spheres and intersected them to give them a curve.  Then I made the
rails by extruding through some shapes along a path.  Then I mirrored
that and added a bridge (made the bridge by extruding through a curved
path again).
  Then I made the wet spot by drawing an outline and making a surface out
of it.
  On to the ship.  I made the sail first
by drawing an outline of it then making a surface out of it.  Then I made
two poles for the mast and cross brace.  Then I made the keel by extruding
a square through a path.  Then made the two rails on the side of the
boat the same way.  Then I made the hull out of lines on the keel and
rail.
  After I did all this in rhino I created meshes of raw smooth triangles.
Sadly of course Povray doesnt support NURB surfaces.  Anyway all of these
objects came to about 20-25 megs of povray source.  If anyone is interested
I will provide the NURBs source and the Smooth Triangle source.  I then used
Moray to scale and place the objects in the scene.  I also created the
wall behind the bottle and the table and the 3 light sources.  I have
2 area lights and a spotlight.  There are also walls on every side of the
rendering to give the various glass objects something to reflect.
I used moray to tweak with the standared textures.
