Animating car wheels

saxo_boy · 17-01-2005, 04:09 PM

can anyone suggest the best way to go about animating car wheels or animating a car ?

I used the reactor toy car - and the car wheels - for this - but this only works with the reactor - i dont want to make a reactor animation.

Are IK / HI solvers the best to use? these solvers are confusing me?

with the wheels pivot at its center u should be able to link them to car body and use a look at constraint to turn them, then just use out of range types in curve editor to make them spin.

Or you could wire the wheels axis of rotation to the movement axis of the car. Not sure if you'd get some gimbal lock problems though...

Thanx for the fedback - iv put this into action - and wow - thank you - it works - lol

@ Sen3D

i link the back wheels to the car body but when i go to rotate them - the car rotates up ? not sure how to wire them properly?

Sometimes that happens. It's to do with local coordinates. What I did was to create a dummy or point object for each wheel & align the position to the wheels but the orientation to the car. then create a larger dummy for the car & align the position & orientation to the car. freeze the rotation of the wheel dummys (hold alt & right click & it should show as an option on the quad menu,) & do this for each wheel dummy. wire the wheel dummys to rotate when the large dummy moves. you'll need to wire keyframexyz (& the relevant axis,) to the correct position axis of the large dummy. don't wire the other rotation controller, (I think its called initial position xyz or something,) as this is used in the freeze rotation. now link each wheel to its dummy, link the wheel dummys to either the large car dummy or the car itself, & link the car to the large car dummy. I think that should work.

ooh pals why all that debates u can have it all using wiring parameters i have good link 4 video tutorial here its :
http://www.max3d.pl/art-other/video-tutorial.php
u will be amazed by simplicity and manupilability , and i can add that we can use reaction manager to make total control for wiring , ok try that and tell me on my mail :ahmed_shalaby2001eg@yahoo.com
and a votre service!

Hi! I wired my car using the video tutorial from the above link and it all worked great...in a straight line. I need to animate the car going around a corner. When the cars going straight the wheels rotate properly but when you turn the wheels they continue rotating on the cars forward axis which results in a kind of wobbling look! I'm stumped!

nice... i will try this once i get home

ahmed_shalaby · 25-02-2005, 01:28 AM

ooh guys i think there may be the solution can be using wiring but assiging the axis coordinate as(local) so when the car body move forward on its local axis z (4 instance) the wheels will rotate along its x axis( 4 instance too!) try it !

isnt there any other way to do it... i cant make it work properly.... a tut mayhab...
