The Project:
When I started my project, my inital aim was to create a room, and then environment map
it onto a project in my room. After creating the room, I discovered that there was no
really good way to turn the entire room into a spherical map without losing some 
part of the room. So, much of my time learning about how environment maps work was spent
on trying to figure out how to spherize the place. Unfortunately, it didn't work out as 
well as I planned.

   So, I divided the big room into two rooms, and created environment
mapping based on two pictures I chose. In order to create a sphere map, I discovered
that adobe photoshop has a feature which allows you to take a picture and spherize the 
middle. So, I took the two pictures I chose and then used adobe photoshop to create
sphere maps of the pictures. From there, I mapped them on to two objects. The first object
I tried environment mapping on was the generic opengl teapot. On the teapot, it appears
as if the teapot is a metallic color, and the painting is reflected onto it. I then
created my own object - a bowl, and mapped the environment map onto it. 

   After creating my two objects, I then went back and rendered the room around it. To 
make the walls and floor more visually appeasing, I found a marble image and texture
mapped it onto all of the surfaces. 

   After creating my room, I lit it. There is one bit light, controlled by pressing
'1' to turn on and off. There are also two spotlights aimed at both the picture
and the environment map on the objects. The light for the teapot is controlled by 
pressing 2 to turn on and off. The light on the bowl is controlled by pressing 3 to 
turn on and off. 

   After lighting, I implemented basic manuerving by the user. By pressing the 'D' key, the
user is brought close to the picture. By pressing the 'd'key, the user is taken farther
away. By pressing the F key, the picture is translated one step to the left. By using the
arrow keys, the user can rotate the room, so by using a combination of both, the user
can effective move around the room.
