Tracy Hamer		Final Scene
	Every Diver's Nightmare


	Inspiration I got SCUBA certified two years ago and have been diving several different places in Mexico. Last summer I went diving on the Palamar Reef at Cozumel. The Reef has these spectacular rock and coral formations that we were able to swim through. They were all right on the edge of this 9,000 drop down into a chasm in the ocean floor. There were some stories about how people would swim through the hole in the rock and then become disoriented and start swimming down into the chasm, thinking that they were swimming up. Originally I was going to have fish floating around the rock/coral just hanging out, but I decided that while it was a good idea, it was a little boring. When I added the shark I figured there wouldn’t be too many fish lazing around with a shark present, so instead of fish I decided to go for more of a dangerous creatures of the ocean theme. Well not that they are really evil, you just hear more bad stories about them so people see them as dangerous.

	Basics of an ocean scene	http://pro.wanadoo.fr/benjamin.chape/tuts2.htm
	I used this tutorial to get the basics on how to create an ocean scene, although mine was actual made fairly differently than the tutorial suggests


	Problems and Solutions My biggest problem was that this scene required so much time and effort put into it. I spent most of my free time working in Lightwave, and although I really enjoy it, it rather cuts down on one’s social life. My second biggest problem was that I modeled my diver in a standing position with her arms hanging at her sides. I had to give her bones to be able to move her arms and lefts and head and everything. At first when I simply tried to draw in bones in Layout, they would affect everything close to them, so I’d try to move one leg, and the one bone would end up moving both legs, an arm, and half the torso. So when I went into class the next time, I got lots of help from one of my classmates on how to create Skelegons in Modeler, and then convert them to bones in Layout using weight mapping to tell each bone what part of my diver it was supposed to affect. The Skelegons ended up working out really well, however I found that once I made my Skelegons into bones in Layout, the original Skelegons disappeared in Modeler, so I couldn’t go back and delete them if I wanted to. Fortunately I had made a couple of copies of my diver in case something like this happened. There probably is a way to go back and delete those Skelegons, but I’ve only had very minimal time to figure them out. I also had lots of problems with giving my shark gills. It took me several hours to get the gills on one side to look semi the way I wanted them, and then I found that I couldn’t just copy and rotate them to the other side of the shark, since he is curved. It turned out to be a long frustrating process of messing with individual polygon points to get it to look the way it does.
