    I'm impressed. Of course I don't know anything about physics and very little of what you say sinks into my brain. But I'm still impressed and I want to be able to do things like this too.

    moderately too-high poly chains for Amy's bike ( about 8K polys nothing tragic )

    today shall be the day where amy rides down the smooth ramp

    and possibly where the bike gets motorized ( maybe an invisible motor, maybe Amy pedaling )

    Well Amy would need to keep feet ON the pedals or "far from" as the pedals on their own would rotate as fast as necessary for the wheels' actions. Pedals can be held still by feet on them. Wheels turn on their own anyway.

    well i guess the descent video will have to wait another day

    Amy may have to give up the heels and wear sneakers ... it's not decided yet

    I swear I can see her thigh muscles moving as she pedals.

    new mag wheelz
    should look better in videos ( less reverse-rotating-wagon wheel effects )

    animating the bike steering was made ( moderately ) easy using the following free scripts available on my site

    mcjMakeTarget - to create target nodes at the exact position of the hand joints
    https://sites.google.com/site/mcasualsdazscripts/mcjmaketarget

    mcjParent - to parent the targets to the handlebar
    https://sites.google.com/site/mcasualsdazscripts3/mcjparent

    mcjCycleFilter to get smooth ( sinewave ) rotations of the abdomen
    https://sites.google.com/site/mcasualsdazscripts/mcjcyclefilter

    mcjAutoLimb to makeThe hands follow the hand targets
    https://sites.google.com/site/mcasualsdazscripts/mcjautolimb

    mcjHoldOn - https://sites.google.com/site/mcasualsdazscripts2/mcjholdo
    to keep her hands gripping the handle bars

    mcjKeepOrient - to keep her neck/head looking in the same direction as the abdomen twists and turns
    https://sites.google.com/site/mcasualsdazscripts/mcjkeeporient

    new Video ! http://www.youtube.com/watch?v=8xVN3h0mH4A

    i corrected the hair issue but the snappy-arms issue surfaced

    well ... it;s supposed to be about the bike

    in theory

    It is a nicer pace though ...

    That any of all that works is amazing to those of us who haven't a clue how to write scripts! Great work.

    now that Amy has her new bike. new wheels, new wedge-sneakers ... we return to the physics .... jump !

    ( the new thing being the triangle mesh ramp/collision surface

    tis related to the physics simulator so it's not like i'm spamming at all :)

    luckily the time machine saves her just before she hits the ground

    She's going to require a parachute! lol ....

    ladies and gentlemen we have jump

    and it was not easy, i had to try different masses for the wheels and bike body

    the thing is, i'm using hinges but bullet-physics includes something specifically adapted to vehicles

    they call it something like ray-casters, the cars are sliding along the ground, suspended on , lets call it vertical jets

    video too !

    Did find this free plane that comes with breaking parachutes [haven't checked the files myself, hopefully all there] Might help the landing ;-)

    the plan if time permits is that she'll splash in the ocean or even SecondLife's animated sea

    we saw

    - hinge between a body and the world ( swing set )
    - hinge with suspension and steering

    today : hinge between two bodies

    presently figuring the way axis and positions are to be specified


    note that Amy ( Aiko3 ) was not part of the simulation, i animated her using the scripts mcjKeepOrient and mcjParent

    The "feet on pedals" part made me think of one thing... would be possible in the future to apply it to the pedals of a car?
