Wheel position and suspension travel

[joevenzon]

I'm not sure I understand exactly what the current Vamos code does, so I'm starting from scratch with how I want the refactor to work regarding wheel position, suspension hinge, and suspension travel.

What I'm thinking makes the most sense is the following: the wheel position that's specified in the car file is the nominal wheel position when the car is sitting stationary (so, the suspension is compressed under the weight of the car). The travel that's specified in the car file is the distance that the suspension can be further compressed past the nominal wheel position until wheel travel stops. Note that this would mean that "zero travel" is actually at a compressed position relative to where the wheel would be in zero gravity. The wheel travels on an arc around the suspension hinge point as specified in the car file.

This is difficult to describe without a diagram. Does it make sense, or should I try to draw one up?

Does this description jive with how people normally talk about suspension travel?
