Playing and seeing what would fit in my rather small bathroom.

Uses lots of tiles derived from Trevor G Quail's.
Blurred reflections for the rotating shelf unit.

All csg which is why the toilet looks as it does (I must learn to use a 
mesh modeller). The sink however is a fairly accurate version of one 
seen in a shop.

You mean, squared?  Remember: isosurfaces, blobs and lathes can be used in
CSG operations, not just the simple geometric povray primitives.

It's meant to be squared, but not as squared as it is, although it is a 
contrast to the basin.

True I wasn't meaning to say anything was impossible in CSG just some 
shapes are harder (for me), I know one can use blobs, lathes and 
isosurfaces in CSG but I'd think a mesh would be the simplest way of 
doing something like this:

Although now you've mentioned it I'm thinking I might be able to improve 
the base using blobs grrr - it was just meant to be a place holder until 
I created a mesh :-)

Isosurfaces are fantastic but I don't think many people use them for 
modelling this type of thing and I'm not sure how I'd get the corners 
with lathes.

Nice stuff. As far as the toilet goes, I amp retty sure you could get very
close with boxes and cylinders if you were patient. Just need to use larger
radii cylinders for the bottom and sides of the bowl vs the top. Then a
torus insteasd of a sphere at the corner. Remember that the tank has a lid
and the bowl two seats, and you'd have something much more satisfyingly
toilet-like.

Anyway, the lighting is nice. The camera is placed fine, but you might play
around with it and see if there is somewhere more dramatic to place it, to
give it that showroom look. Looks good as-is, too.

The third place winner of the last IRTC-round

http://www.irtc.org/stills/2006-10-31.html

has a very nice toilet made up from CSG. I didn't look at the code, but
maybe it will help you.

Ah now I'd have guessed that was a mesh but reading the text it's just 
very impressive use of superellipsoids - ok if he can do that with csg 
superellipsoids ..... thanks.

try this quick hack based on that picture.  lacking a proper seat yet.

/* begin code */

/**
 * toilet seat.
 * complex modelling with blobs and little effort.

 * code can be reused and redistributed at will by those wishing to improve
povray
**/


#declare t_toilet = texture {
 pigment { rgb 1 }
 normal { bumps bump_size .12 turbulence .3 scale .4 }
 finish { diffuse .5 ambient .4 phong .7 phong_size 40 }
}

#declare toilet_base = blob {
         threshold .2
         // seat
         cylinder { -1.2*x,1.2*x 1 1 scale .6*x+.9*y }
         // seat "flattening"
         cylinder { -1.2*x,1.2*x 1 (-2) scale .6*x+.8*y translate y*.65 }

                // base
         cylinder { -.6*y,.6*y .64 2 scale y*1+x*1.4+z*.8 rotate -z*10
translate x*-.2-y*1.2 }
                // base "flattening" from the sides
         cylinder { -.6*y,.6*y .64 (-2) scale y*1+x*3.4+z*.8 translate -z*.9
rotate x*10 translate x*-.0-y*1.8 }
         cylinder { -.6*y,.6*y .64 (-2) scale y*1+x*3.4+z*.8 translate z*.9
rotate -x*10 translate x*-.0-y*1.8 }

         // back "clipping"
         cylinder { -y,y 1 (-1) scale x*.5+z*2 translate -y-1.2*x }
         // bottom "clipping"
         cylinder { -x,x 1 (-5) scale y*.6+z*2 translate -1.9*y }
        }

// fill light
light_source { (-4+8*y)*2 .5 }

background { rgb .96 }

// "scene"
union {
        light_source { (4-8*z)*2 1 }

 union {
                object { toilet_base }
                // water box
         superellipsoid { <.14,.14> scale x*.3 scale .76 translate y*.9-x*.7
}
         // water box top
         superellipsoid { <.2,.2> scale x*.36 scale y*.04 scale .76
translate y*(.9+.76-.06)-x*.7 }
         texture { t_toilet }

         translate -y*.2
         no_shadow
 }

        rotate y*30
        rotate -x*20
        translate z*6
}

camera { angle 40 }

/* end code */


I like blobs very much for modelling complex, continuous free-flow shapes
without meshes.  And it suffers from no polygon vertice showing. :)

isosurfaces are good for bending metal objects, for instance...

I'm not sure lather are good for that.  They are great for bathshower
handles, for instance.

Hi Verm.

   I think you're off to a great start and I like your modeling work. Keep
it up!

   I think a few plants as well as some soap bottles and a towel or two
would add a nice touch and make the image look more believable.

   Also, I find Jaime Vives Piqueres' LightSys lighting system capable of
producing some very realistic, warm lighting and I love it.

See his techniques section: http://www.ignorancia.org

Rock on,
George
