Class 4/20/10 tuesday

12:30-3:00 PM

1. Presented my alpha ball bounce sequence to Blyth
2. It needed a more realistic bounce to it, the physics were off and needed to be corrected
3. Looked at an example of ball bouncing from an ad 
4. Looked for a picture sample displaying the physics behind ball bouncing. Blyth found some sites and emailed the links for them to my Montserrat account (I haven't been on a computer since tuesday, so I haven't gotten to look at them yet)
5. With the physics of the ball bounce there were two samples, one in which the height was the only thing that decreased, the other: both the height and the distance it landed each time decreased (that was the one that I had been trying to replicate)
6. Blyth and I set up a spline but it wouldn't quite complete the task, it was discovered that it would probably be easier to animate the shape especially when Blyth had found a function in the timeline window that allowed for alterations could be made by changing the display to its graph function
7. Blyth had figured out the math, which frames to set the motion to starting with the addition of 15 and have the number decay by for each cycle
8. Once the frames were figured out I set it up on my computer with the starting height being 1 block (ten squares) and base width being  1 block; the pattern: height decrease by 1, base width decrease by 1/2 a square.
9. The squash and stretch was rather funny to start working on; I had put the values into the wrong places the ZX were supposed to be the same values at the same interval and Y the opposite value, I've fixed that but the values input into the animation need to be altered so that the gravity with the 3d ball that I'm using comes out so that its regular sized when its at full height on each arc and squashed at its landing point at the base
