2
Q
Keyframe Animation
A
Interpolate motion between selected points
Paper: Hearn & Baker
3
Q
4 Ways to simulate acceleration
A
- Constant Speed (a=0)
- Increasing interval size (a > 0)
- Decreasing interval size (a < 0)
- Combine 2 + 3 for smooth in/out.
4
Q
Direct Motion Specification
A
A user programmed animation sequence where every point in time is specified
Like a bouncing ball y(x) = A| sin(w + th)| e^{-kx}
5
Q
Linear Interpolation
A
Picks a point on the line between two points dependent on time.
Con: has discontinuous derivatives between different segments.
