CSE 167 - Final Project
Readme file

This project was implemented using the lighting and rotation used in 
previous programs with the addition of texture mapping. This program 
was designed based on christmas time. It is a room that has a 
christmas tree that has lights on it. They can all be turned on or off
by pressing the '2' button. On the far back, there is a fireplace
and on the left, there is a table. On the walls, there are frames
with wallpapers using texture mapping. Also, the frames (5 of them)
are done by using texture mapping. The door on the left wall is also
texture mapping. The fireplace was actually cut out from the wall and 
the cones representing wood were placed behind the wall. The fence was
drawn by lines and the bricks around the fireplace was also done by
texture mapping. The christmas tree was built by using 3 cones, one
on the top of the other and the lights were placed around the tree
using small spheres. Some balls are just ornaments, others are lights
that can be tuned off and they "disappear." The table on the left was
completely filled with texture mapping, including all the for legs. 
On the floor, there is also texture mapping on the carpet and also 
on the floor. There are also some gifts on the floor around the tree
and on the table.
The commands to use the program are: 
R: Increase the angle of rotation to the left and right
r: Decrease the angle of rotation to the left and right
D: Move the viewew to the front, closer to the back wall
d: Move the viewer to the back, further to the back wall
1: Turn on and off the room white light on the center of the ceiling
2: Turn on and off all the lights of the tree
Up: Move viewer to see from upper side. The maximum angle is 5 degrees
Down: Move viewer to see from the bottom. The minimum angle is 0 degree
Left: Rotate viewer to the left. This only works if the user is closer
      than the default distance to the back wall. This avoids the user
      to rotate around, viewing the outside of the room.
Right: Rotate viewer to the right. This only works if the user is 
       closer than the default distance to the back wall. This avoids
       the user to rotate around, viewing the outside of the room.
