IMAGE DESCRIPTION: 


  A child sets up mom's pots and pans for a little noise.. ahem.. music in the
kitchen.


DESCRIPTION OF HOW THIS IMAGE WAS CREATED: 


  I started by creating a group of rooms with simple CSG Booleans. I added some
space 
  off-camera for more realistic reflections/radiosity.
  
  The floor is a while loop of superellipsoids with a stone and solid color
texture averaged
  together. The averaging tones down the stone texture a little bit. Variable
reflection and some 
  normals round it out. There's a simple textured plane for grout.
  
  The window and doorwall are put in with macros I tweaked from an earlier IRTC
entry I did. They
  use a spilin prism for the molding, and some CSG construction for the rest.
The curtains were
  modeled in Rhino. Double-illuminate and a filtered pigment gives them a
translucent look.

  The flowers and plant were modeled in Xfrog and translated through Rhino.
  
  Picture frames are CSG construction done with a macro.
  
  Oatmeal and disinfectant wipe containers are CSG, with image maps I scanned
from the actual
  product labels.
  
  Pot and pans are spilin lathes, with Rhino modeled handles. The brushed copper
texture (most
  visible on background pan) was adapted from a texture found online by Rune S.
Johansen. (I still
  have no clue how it works, but it does.)
  
  The concert note is a heightfield intersected with a mesh from Rhino. I tried
using just the
  mesh with a partially transparent image_map but it caused render issues with
the media that
  I couldn't figure out.
  
  The barely-visible deck rail is CSG.
  
  I used a sky_sphere with a gradient to give some blue color to the sky.
  
  Most of the rest of the objects are CSG construction and/or Spilin created
objects with the 
  exception of the following which were modeled in Rhino and imported: spoons,
faucet,
  cabinet handles, chairs and cushions, part of paper towel roll (curved end).
  
  The lighting was one of the most difficult parts of the image. I used
radiosity for non-direct
  lighting, but didn't get the results I wanted with one light source (sun).
Adding small "fill"
  lights in the room also didn't give me the right results. What I ended up
doing was putting
  large area lights where the door-wall and kitchen window are to fill the light
out more. This, 
  in addition to a very bright light for the sun game me the effect I wanted.
 
  Focal blur, and some scattering media to create some haze in the air give the
image a little more 
  realism and also bumped the render time up substantially. =)
  
  I saved my radiosity calculations to a file so that I wouldn't have to worry
about inconsitent 
  lighting with multiple renders. Using my computer for videogaming in the
evenings makes it
  unlikely that my machine will stay up for 11 days straight. I ended up doing
the render in about 5 
  pieces.
  
  The zip file does not contain any meshes to save on file size. If anyone wants
them, go ahead and
  email me.
