Hello! Welcome to my CS 110 Wiki page.

[edit] About Me
I'm a senior biology major at Mount Holyoke College, and next year I'll be attending medical school. I'm a co-Captain of the Varsity Swimming and Diving Team, and also a member of student government. You can read more about the Swim and Dive team at our website
My favoriate restaurant at home is called Hole in the Wall. Located in Northbrook, Illinois, it's a small place (hence the name) so you might have to wait for a table (no reservations), but the great Southern Italian food is well worth sticking around for.
[edit] Classwork
I'll be posting work from CS 110, Computer Animation, on this page. Get excited!
[edit] A Simple Model: Lab 2
Here is a look at the first model that I made in lab. It's a model of a puppy, and to creat this character I first defined the head and face, and then moved onto the body and legs. I created a new brown color to do the body, and added lights to better illuminate the scene as well. To add a little more I placed a fire hydrant in the scene.
[edit] Working with New Shapes: Lab 3
In this lab I created two different tropical drinks. The first is a more simple model, the shape of the glass is just a hollowed out cylinder. The second and more exotic glass uses many hollow pieces, including a hollowed lathe object to make a unique shape. Both images include ice cubes (mesh objects) and a tropical drink umbrella with fruit. The orange is an intersection of a cylinder and a rectangle. The umbrella itself was created using the difference command, subtracting out the center of the cone. This same idea of using differences was employed for the glasses in order to make them hollow. I'm showing a top view of the second glass so that the ice cubes can be more easily visualized. The third glass I created is a new shape, but uses the same principals of differences to create an empty effect that could then be filled by another color to create the liquid portion. The final image has all three drinks that I created sitting on a tray!
[edit] Lab 4
For this lab I created a marble as well as a realistic scene. In both of these scenes I created new materials to use in the images. New materials I created include gold metal, mirror, glass, wood, and a semi-translucent cloth for the lamp shade.
The living room scene is comprised of three major objects: a lamp, a mirror, and a table. The lamp is made of basic shapes and new materials, except for the lamp shade which is a lathed object. The mirror is also mostly basic shapes, but incorporates differences in the decorative finishes. Finally, the table top is a scaled cube and the bottom piece of the table is the same as the bottom legs of the mirror, just re-scaled for the proper effect. The books on the table are also made using differences.
[edit] Lab 5: Suprise!
The goal of this lab was to create a scene in which someting that cannont be seen from one camera angle is revealed by a second camera angle- a "suprise" image becomes visible!
For my scene, I created a rainbow. The suprise it the pot of gold at the end of it! This scene is not meant to be realsitic looking, it is meant to have an animated loot to it, so I have extremely bright colors and lighting. The rainbow was created by making a square of color and then lathing that square. Each color lathe was placed next to each other and out into a group. Then, the bottom half if the circle of color was taken away using a Difference. The pot of gold is formed out of differences and intersections of spheres, and the clouds are lots of circles piled together. Finally, the four leaf clovers are primitave shapes put together and scaled in a group. Happy St. Patrick's Day!
[edit] Lab 6: Replicated Objects
In this lab I used replicated images as well as shared images. The shared images in this scene are the balloons made by Carol Stafford (and their latex material) and the presents made by Ginny Taylor. I adjusted the presents a bit as well. I added the balloons randomly to the scene using a function. I used the multiAdd function to add candles to the birthday cake in an orderly fashion, this is best seen from the overhead view. The candles, table, and cake are all new images. Finally, in this lab I also used a new technique for the first time, I used .png files as materials to create a realistic wood grain for the table and carpet for the floor. Notice that in the two images of the whole scene the balloons look different- this is because each time the image is genereated the balloons are added raddomly!
[edit] Lab 7: Bezier Curves
Part 1
Here I experimented with some curved objects based on bezier curves. Three are just pretty shapes/abstract designs, but one approximates the shape of a question mark (this was surprisingly tricky!). These shapes were made with prisms and lathes.
The second part of this lab was creating a bowling pin. This shape is complex and was made with lathed bezier curves. I woulden't have been able to make this as well without the use of bezier curves.
Part 2 The second part of this lab is an actual animation. In this case, I chose to add to part 1 of this lab, the bowling pin scene. I created a bowling ball with differences to make the finger holes, and then I applied two types of movements to the ball: it moves down the lane and rotates about it's center as it rolls. Both of these movements are part of a single function.
[edit] Final Project
For my final project I decided to create another animation. I have a miniature golf movie- a golf club swings back and forth to putt a golf ball under the spinning windmill obstacle. The ball curves and goes into the hole. The camera also moves in the scene.
I used a wide range of techniques in this scene. First, the objects vary in composition. I have differences, meshes (note the pyramid mesh in the windmill- I had never done my own mesh like this before!), lathes, prisms, lofts (a new technique for me), and more! I also created new materials, some with surface images like the astroturf, and some from scratch like the "whiteWood" and the brown leather for the golf club. I used multiAdd to create the windmill lattice, and random multiAdd-like functions for the clouds and flowers, and I used a patch mesh to create the curves bezier surface.
In the animation portion of this project I used three main functions. The first is the golf club swinging; I used this twice, once for each direction. Another function is the golf ball moving; it translates and rotates about it's center x-axis so that it is realistic. Finally, I used a function to make the camera move. All of these functions include a paramater to make the windmill spin continuously. The windmill needed some problem solving throughout the creation of this animation; in my first attempt I based rotations on degrees per segment, which meant that is spun at different rates based on how many frames were in a segment. To fix this I changed the function to go by degrees per frame, making the rate of spin constant. Also, I change the camera angle with some of the animations so that it follows the call more closely.
Watch the animation and also take some close up looks at the details of the scene! This took MANY hours and I'm proud to the result. Hope you enjoy!
