TITLE: Cacophony COUNTRY: USA RENDERER USED: MegaPOV 1.2.1 TOOLS USED: Paint Shop Pro X (compositing multiple renders, conversion to jpg) Rhino 3D 3.0 Xfrog 3.5 Spilin Julius Klatte's rounded box macro RENDER TIME: about 11.5 days or a little under 300 hours HARDWARE USED: AMD 64 3200+ (2.0GHz), 2GB RAM, WinXP 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.
