JPGFILE: kani.jpg ZIPFILE: kani.zip RENDERER USED: POVRAY 3.02.watcom.win32 TOOLS USED: SPatch 1.5 PaintShop Pro 4.14 Various photos "Fish of the Maldives" by Andrea Ghisotti RENDER TIME: HARDWARE USED: 233MHz PII 64 MB IMAGE DESCRIPTION: When this topic was announced, I had just come back from a holiday in the Maldives (Kani Island), where I sent a lot of time snorkeling, so this shows a typical scene from underwater there. DESCRIPTION OF HOW THIS IMAGE WAS CREATED: The sea is a transparent plane with a ripple normal, with caustics added. I wasn't happy with the effects of using fog (its probably too linear) so the distance shading was done using a sequence of planes each of which had lower transparency, and darker colours than its predecessor. Each has a crand added on to show the particles in the water. This had the added bonus of making the sun's rays visible in the water. The corals are a mixture of blobs, and scaled spheres arranged at random. The fish really are the colours shown here. They have been matched from photos I took (a few of these are in the zip file) All the fish were modelled using Spatch. Blue fish - Blue Sturgeon approx 15-20 cms long. One of the more common larger fish but usually solitary. Black / white fish - Humbug Damselfish approx 2-5 cms. These were everywhere and lived in clouds of about 20 fish. Orange fish - Clownfish approx 5-7 cms. These stayed within the big purple anemomes. About 2 or 3 per anemome. Yellow fish - Long Nosed Butterflyfish. I only saw one of these and managed to get a photo of it ! Karl Manning karl@pemail.net 25/10/98
