CS 684, Final Project
"Coke Bottle"
Ryan Graham
**************************** Work in
Progress ***************************
This will be my final project for CS684. What I plan to do is to
render a scene containing a 8 oz glass Coca-Cola bottle and
take a picture with a digital camera of the same scene, then
compare the results.
Step 1: Model the Coca-Cola bottle.
The first thing I did was use
a Digabot 3D scanner to get a 3D point cloud of the bottle.
Thanks to:
-
H. James de St. Germain
For taking the time to show me how to scan the bottle.
-
Nathan Mead
For helping me convert the point cloud into a triangulated mesh.
The next step I took was to reduce the massive
36000 + polygon mesh down to ~7100 polygons. To do this I used
Softimage's
Polygon reducer (Beautiful program, despite being owned by Microsoft).
Next I used Nate
Robbins Smooth program to generate nice vertex normals for the mesh.
The smoothing angle used was 90
degrees. Below is a bad picture of the
real Coca-Cola bottle next to a quickly rendered, opauqe gray-scale image
of the
model (it's hard to tell, but the model
is a reasonably accurate representation of the real bottle)
Finally I need to model the inside
of the bottle (So the glass can have a thickness). To do this I plan to
use (once again)
Softimage. The plan is to scale the original
mesh down a little and use it for the inside of the bottle. Seeing how
the model
is going to be really important, a lot
of time will be spent here to try and get it right...
Step 2: ..... to come .....
