TITLE: Home COUNTRY: USA WEBPAGE: None RENDERER USED: POV 3.5 TOOLS USED: IFranView, PhotoShopLE, POV 3.5, Plant Studio, FractInt, Little Gray Cells RENDER TIME: about 9 hrs HARDWARE USED: 2.4 Ghz Pentium on Windows 2000 IMAGE DESCRIPTION: This time around I wanted to make an original picture with a modern theme. The house is of my own original design. I've tried to incorporate themes of earthiness, harmony, and oneness through the use of earth tones, torri, and cylinders. This underground house represents the idea of home. Not only is it a home to live in, but it reminds us of our home in the universe. There is a close tie to nature as the universe is brought indoors with the mural and sundial in the second level entrance way. Standing near the globe on the lowest level and looking up provides access to the outside world and the rest of the universe. DESCRIPTION OF HOW THIS IMAGE WAS CREATED: Three POV pictures were created and combined into a single mosaic. I wish I could have developed more views of the lower level, but the 250K file size limit prevented additional views. Since the topic was Architecture and time was at a premium, I did not go overboard with interior design, furniture, and other furnishings. TOP PANEL: This panel shows the outside of the house. The sun is an area light. The stones and mailbox are superelipsoids. The entrance tunnel is a sphere sweep object differenced with a cylinder. Thanks to Gilles Tran for his Makegrass macro. I created two different grass meshes and placed them at random around the house, avoiding the actual area of the house. Thanks to Jeremy Praay for his Weeds macro. I created 2 different types of weed patches and placed them near the house. I used plant studio to design 2 different types of flowers and distributed them in an arc around the house perimeter. MIDDLE PANEL: This panel shows the house entrance at the bottom of the entrance tunnel. A sundial gnomon is suspended above to cast a shadow on the sundial-inlaid floor. An image map of the earth rising over the moon's horizon was mapped to the inside of a hollow cylinder. The spiral staircase was developed as a macro using trig functions and a little bit of math. The reflecting sphere on top of the staircase is purely ornamental. The mat between the entrance tunnel and the house entrance is a sphere sweep object that is scaled very small in the Y direction. The telescope and sundial are pure CSG. Sunlight enters from the top, through the large glass window. One additional shadowless light is placed near the center of the floor to brighten up the entrance way. The second and third levels of the inside of the house is a single include file, so that the view from above and the view from below are consistent. BOTTOM PANEL: This panel shows the living area. Since I only had space for one view, I decided to place the camera near the globe in the central area below the skylight and view part of the kitchen and living room. I created the globe by starting with a GIF image I found on the web. The image was converted to an hf_gray_16 height field using POV. Then the height field was recombined with an image map, scaled, and remapped onto a sphere. The bubble wall, separating the kitchen and livingroom, is a hollow box, ior 1.7, filled with spheres, ior 1.0, that are placed using an X-Y grid system that is perturbed to generate somewhat random deviations. The spherical bubbles are filled with emitting media to make them look like they are lit from an unseen light source. All the cupboards and cabinets are CSG objects. The spiral lamp is based on the spiral staircase macro. The painting on the wall is an image map of a fractal I made with FractInt. The livingroom floor is a prism object textured with an X-Z pigment map. The kitchen floor is a prism object with inlayed boxes textured as stones. I used fairly high quality radiocity settings in the top and bottom panels. The middle panel did not benefit much from radiosity. pretrace_start 0.08 pretrace_end 0.008 count 400 error_bound 0.12 recursion_limit 4 IfranView was used to convert the POV PNG files to TGA files which were then copied into PhotoShopLE. The combined image was cropped and saved as a jpeg file to meet file size requirements.
