IMAGE DESCRIPTION: This image is an example of how to make seamless liquid textures within POV-Ray. The main file has 6 liquid examples, all of which can be animated. The image for the contest is a composite of two of these textures: ice water and fresh water. The others are ocean water, swamp water, blood, and lava. DESCRIPTION OF HOW THIS IMAGE WAS CREATED: POV-Ray's texture patterns, at least the interesting turbulent ones, do not normally tile. I have tried many offset duplication methods: all failed. Periodic functions do tile well, but they don't make for very nice textures. As it turned out the secret was to create a pattern function and feed it periodic variables. Normally my projects consists of at least 3 files: one for scene layout, one or more for object definitions, and one for textures. This one needed only 1 file for everything, and a fairly small one at that. A simple file for a simple, but interesting, purpose is one interpretation of minimalism.
