Need to create some kind of dynamic constraint ?

[Virbhadra Gupta]

Hello
I am trying to create script that will connect wheels to ground.
My approch is i am trying to connect only translation y with poly mesh.
Geometry constraint is only option.
But we can't control connection it connects all transactions attributes.

Any suggestions will be helpful.

Hi Virbhadra,

You wann to make something like this ?

Try creating a ground and a 9 vertex plane, "Transfer Attributes" in world-space along normal plane -> ground, and viola, you've got vertices that snaps to the ground. Now you can e.g. attach follicles to that plane to get translate and rotation out of it, and use those to drive your wheels.

Hey thanks
Nice idea but when i create follicle it is not following that 9 vtx face.
Can you tell me how to attach may be i am doing something wrong.

Hi,

For make this I don't use geometrie constraint. I tryed to make it with this constraint but isn't a good solution. Géometry constraint don't keep distance between all object if the ground isn't plane.

So, in first, i make a basic node for use mesh/nurbsSurface intersect of maya API.

Ray position is your wheel position.

Ray direction is a normal of your square with plane points are wheels positions of your vehicul.

After I implented some function like intersect with given distance, smooth interpollation when you leave intersection (last intersect point and origin point) and other...

Now I use this node for facial intersection too like lip and theeth.

[Virbhadra Gupta]

Yes,
Something like that.
Can you tell me overview to make it.

Seems bit complected, i am beginner with scripting.

can you help me to create this node or share this node ?  

[Rémi Deletrain]

It's not possible to give you my node because is a property of QuanticDream.

But it's possible to give you an exemple. :)

Thank you for your help
I will try to create it.
