Wheels on a car: apply to the wheel rotate in z channel
rz = car.tx / (2*3.1416) * 1 * 360
wheel car pi wheel size 1 rotation
Windshield wipers: apply to the wiper rotate in x channel
rx = (sin (.9 * time) * 45) + 10
wiper sine speed time degree offset for position
Volumetric squashing for a ball: pg 26 Learning Maya
apply to the ball scale in x channel sx = 1/sy
apply to the ball scale in x channel sz = 1/sy
Start an Expression at a Certain Frame:
if (frame > 50)
tx = 0;
else tx = 50;
If the value frame is greater than 50 translate x will = 0, otherwise translate x = 50.
Start and stop an Expression at a Certain Frame:
if (frame < 50)
tx = 0;
else if ((frame >= 50) && (frame <= 100))
tx = 50;
else if (frame > 100)
tx = 2;
Imbedded Sin Waves for a Random Effect
ty = sin (sin (.5 * time) * time);
Use noise for a random effect
ty = noise(time);
