IMAGE DESCRIPTION:

        This is an image of a typical farm in the 1930s, as the one
where my great-grandparents lived with other families.  Every object
in the scene tries to evocate the life in that epoch: the sink with
the bucket used to fill it, the basin... the daily use of "old
technology".


DESCRIPTION OF HOW THIS IMAGE WAS CREATED:

- sewing machine: a lot of height fields, basic primitives (tori and
  cylinders) some CSG and sPatch objects

- walls: isosurfaces

- floor: height field

- scissors: height field

- chairs: the framework is a sPatch object, the straw is a set of
  sphere sweeps placed by a macro;

- clock: primitive objects (spheres, cylinders), height fields
  (hands);

- lantern: cones, cylinders, height fields, sphere sweeps and an
  isosurface for the glass and the wires around it;

- iron structure under the basin: isosurfaces and tori;

- shelf benches: isosurfaces;

- threads (on the sewing machine and under the chair): sphere sweeps;

- cart: primitive objects;

- straw (in the cart and the cowshed): sphere sweep objects randomly
  placed by a macro;

- basin, thimble, cloth on the chair, table, candlestick on the table,
  pot on the wall, dishes in the sink: sPatch object;

- horse: 3ds model I downloaded from the "3D cafe" website and
  converted to POV using Anim8or (3DS -> OBJ) and PoseRay (OBJ ->
  POV);

- illumination: a parallel area light outside the window, two area
  lights placed on the two window frames, some lights used to
  illuminate single objects (the sewing machine, the shelf, the pot
  hanged on the wall...), radiosity.

- the image reflected in the windows is a painting by Silvestro Lega,
  "Il pergolato" (the arbour), painted in 1868;

- the picture above the basin was taken in the late 1910s; see the
  "photo.jpg" and "photo.txt" file (both in the ZIP) file for more
  information.
