MPH in Tempo
I am doing a courtroom animation reconstructing a car accident. I want to use
the TEMPO routine to adjust the speed of the vehicles involved. I think it
should be possible to make the vehicle, setting up its path and setting the
following: From point A to point B the car was going 55 mph, at point B the
brakes were applied (where the reconstructionist has measured the skid marks to
start). Then use TEMPO to figure out how to animate the area from point B (55
mph) to point C (point of impact where I know from my reconstructionist
information the speed of the vehicle would have been 44 mph. And have the
vehicle stop completely at point C (the point of impact). I set up the movement
by setting a constant velocity for the car of 55 mph. Applying that, I noted
the frame where the car passed over point B. I go into TEMPO and using the
velocity curve add a point at that frame at 55 mph. Here's where I am lost. I
know where the point of impact was ( I have the distance set up from point B to
point C with the models already) How do I tell TEMPO where (or should I say
when) I need the car to be going 44 mph?
Is this description confusing. This is really driving me nuts. Any help is
greatly appreciated. In a nutshell I need to set tempo up to make the car go
from A to B at 55, then decelerate from 55 to 44 by the time the model reaches
C.
