TITLE: Glass Pavilion COUNTRY: USA WEBPAGE: none RENDERER USED: POVray 3 for Windows TOOLS USED: POVcad, PC Paintbrush, Conv2jpg RENDER TIME: 3 Days 5 Hours 34 Minutes HARDWARE USED: 486/66 DX IMAGE DESCRIPTION: A pavilion made of glass sits on a shiny yellow glass surface with odd patterned disks receding to the mountains. DESCRIPTION OF HOW THIS IMAGE WAS CREATED: The mountains were created with a height_field from a tga created with PC Paintbrush (about 4 hours to render), which was then placed into the final scene as an image_map cut-out in order to help shorten the render time. The disk's layout is set by using random numbers in POVwin3 and a #while loop to place 50 or so disks, some of which are off the edge of the scene. The seed value was changed a few times until the effect was what I wanted. The disk in the foreground was placed manually to get it just right. The pattern on the disks is an image_map created with PC Paintbrush. The disks are hollow with clear areas in the pattern. The pavilion is made of beams sitting on top of pillars. The beams are the difference of 2 spheres and 3 planes; the inside sphere is scaled so that the beam's thickness narrows near the top. The capstones on the pillars are a union of a box and two cylinders with little spheres subtracted for detail. The pillars are a cylinder with smaller cylinders subtracted for detail. The base is a box and a lathe for the roundish part (data imported from POVcad). The glass texture is a light cyan with a high filter value. The circular placement of the beams and the pillars is accomplished with a #while loop. The number of pillars is set by #declare variable and can be easily changed. Something similar to this could be used to place any circular group.
