Rauks in morning light.

"Rauk" is the local name for these limestone formations that can be found in the coastal areas of Gotland, a Swedish island situated in the Baltic sea. Rauks are fossil remains of coral reefs that were formed some 400 million years ago when Gotland was the bottom of a shallow sea near the equator. The rauk-objects were easy to create using Blobs. To give them a rougher look I used Applique with a fractal noise image. If they got too rough I used the Smoothing tool to make them a bit smoother. The rauk-objects uses two procedural textures, the Noisebump texture and a fractal noise texture that I've made. The Noisebump texture is used in several layers, each with different scale and bump size. The fractal noise texture is used mainly to give the surface some apparent structure in the shady parts of the objects. It looked kind of flat and unnatural without it. The water is a ground object using another procedural texture that I've made. It is a bump texture simulating waves. The reflectivity was set to 100 % (RGB 255, 255, 255). The fog was created by applying a fractal noise texture to a plane object. It is the same texture that was used for the rauks, but now affecting the Fog length instead of the color. The fog-object was placed so the camera would look through it. The main light has a red tint and is set to cast shadows. The intensity was set to 512. There are four lights used to lighten the shady sides of the rauks. Each has the intensity set to 16. The image (640x480) took 10 minutes to render (raytrace) using Imagine for Windows on a Pentium 90, 16Mb PC.
