JPGFILE: plouf.jpg RENDERER USED: RayDream Studio 5.02 TOOLS USED: RayFlect 4Elements & RayFlect Blubble RENDER TIME: 5 hours at 1024*768 and 5 levels of transparency HARDWARE USED: PII 300 - 64 Mo RAM IMAGE DESCRIPTION: Initially I wanted to make the ducks look like they were made out of water, born from the water and taking off from their mother element. I'm not sure this is obvious in the final picture, as my first water ducks were not that realistic; I had to add some color in their texture in order to make the image feel "happier". DESCRIPTION OF HOW THIS IMAGE WAS CREATED: water made with a procedural texture thanks to 4Elements; color of the water due to a dark reflected background; ducks from a model from the RayDream CD (easy... I know. But I tend to consider composition before modelling); the texture of the ducks is 95% transparent, 20% refractive, with a color both in the transparency channel and in the color channel (not the same, hint !). Glass/water is VERY hard to attain in RayDream, probably due to the raytracer that is less good for this than POV. Basically I had to trick with lots of light sources to obtain the desired reflections and highlights. Reflected objects or backgrounds are key elements for realitic glass/water.
