JPGFILE: akstaing.jpg ZIPFILE: akstaing.zip RENDERER USED: POVRAY 3.0 TOOLS USED: pencil and paper for the design, cjpeg to convert the tga to jpg RENDER TIME: 1 week+ HARDWARE USED: 586/133 running linux, Sun SPARC 5 IMAGE DESCRIPTION: An empty glass sits on the desk in remembrance of... DESCRIPTION OF HOW THIS IMAGE WAS CREATED: The wineglass is a CSG object using one of the standard glass textures from glass.inc. The bowl of the glass is simply a difference of two spheres, each scaled slightly differently to make the glass thicker in the middle and thinner at the top. The stem is a cylinder, but with parts of the glass cut away to achieve a "carved" effect. The stained glass lampshade is also a CSG object, using a custom texture for the glass and lead. After discovering that the render time for the lamp was too long, I redesigned it and cut down on the complexity of the POV source file -- this resulted in a substantial decrease in the render time.
