Which is best way to animate wheel rotation with flat tire?

There is probably some fancy rig for this somewhere.. I can think of one way of doing it that is somewhat simple.

Separate the rim from the tire, make the tire a child of the rim. rotate the rim, make a simple expresion or use nodes to rotate the tire negative to the rims rotation on the forward rotation axis, so it basically counter rotates what the rim does and it stays static. As it is static you can now use morphs, bones what ever you want to simulate the lower presure. All the textures and shading of the tire should use the rim as the "reference object" so they rotate with it.

Easiest way is to use a displacement tied to Y distance to simply smoosh the geo. As the wheel rotates, the displacement stays fixed (relatively speaking) and you get a smooshy, rotatable wheel.

Much thanks, Danner and RebelHill for great and usable suggestions!
First i have try that way http://www.youtube.com/watch?v=FPHq2PM2yTk&feature=youtu.be
If that not enough will try suggestions.

Would the Raycast node be applicable in any way for this?

You might still find the book relevant enough to buy, I'm always looking up my copy for various info.

Go to here and find Chapter 22 - read pages 792 - 794 incl.

But LW can't do nothing like the below video right? Wanted to know. Metalink might pull some tricks and a field of bones too, but hard to setup no?

well LW doesnt have a native lattice deformer, but for simple shapes such as a wheel/tyre you could pretty much the same thing using nodal, yep.

Nope, LW don't have Lattice Defomrer (or FDD as it's called in MAX) :(.

It would be much much easier if it had.

not sure how he did it, but interesting...

thats done using the scaled parent space (oval eye) trick, with plane effector to flatten the contact geo.

but how is the wheel rotating, a morph perhaps?

RebelHill

same way the eye rotates... It just rotates, plain and simple. The effector flattens whatever part of the geo comes in contact and the stretch comes from a scaled parent space.

ah, been such a long time since i dealt with scaling the bone, forgot it could scale in both width and height... :P

There's now a lattice deformer plugin for LW.

Any videos of use?

However, I decided to use Texture Displacement as more opportunities to model form (shape).
For wheel rim i use Morph.

So my method worked for you too then :)?

You showed very good results, great work.

So, are the 3 layers one each for X, Y, Z????

Outstanding work!

All flowers to Lewis! But this seemed to me the easiest method for this case.

Yes. Just follow Lewis tutorial.

Difficult to to reach on the ground rubber thickness. Need a little lie.

Tried to do the tire and do the flattening with some morphs with this but I don't have 11.6 setup for me yet and Raycast made Layout freeze several times, so I went with simpler.

Following the 11.6 Content scene "Raycast_Deformation", there's an eye and a simpler mesh sphere to deform it with some morphs applied to it (cilinder and cone) but you can just scale it and will get the eye deformed.

You can see the Eye is spinning on the Pitch and still sticks to the deformer.

I couldn't make a rest position, so if there's any offset it will be felt. The proper way like I shown in the previous video in Softimage would be to have two copies of the deformer, one to define the base position, the other to define the offset. So it would be not the eye getting it's closest location to an 'S' shape, but getting it's closest location to something that after deforms like an 'S' shape and the eye follows. Right now it's whatever is in range.

Hope it inspires someone :)

There are Morph deformation and Texture rotate with channel follower.
