The Blue whale project is a post showing how to make realistic animals in Second Life. This video shows the result of following the instructions at secondlife.mitsi.com/secondlife/code
This whale is animated to jump, splash, and swim. It will flip it's flippers and flukes, all at the same time smoothly, and it can be easily made to signal other, outside effects, such as commanding a bridge to open for it so it can swim under, as well as play sounds at key points in it's journey. I'll give you the sculpts, scripts, and explain step-by-step how to make my blue whale, so that you can edit it and change just the bits you want to change for your own purposes. All the scripts are available in my LSL Script Database and Library, and each is explained step-but-step individually.
I'll show you how to make any whale or other fish swim with it's fins, broach the surface and make a splash, jump, spray water out the blowhole, and splash again when it goes back into the water. And you can ride on it, too, around and around, on any path you want to program into your new blue whale. You will even be able to ride around on the whale, entirely outside of the normal sim boundaries.
