Default Auto form

PLugin for this? if not it would be a good addition
I was wondering if there is a way to have objects form to another object.
For example,
Say you have two spheres. Now you want the first sphere to touch and change as you push it into the second sphere. The vertecies would change to the shape as it hits the 2nd sphere rather than going through it.

Sorry if what I said is unclear.
Exampe #2:
Lets say you have a piece of clay(sphere) and a metal cube. Now you take the clay sphere and push it onto any part of the cube, the clay is going to form around the cube insted of going through the cube as it would in ac3d.
Hope that is a better example.

The reason for me asking is that im not very experience what molding/shaping in ac3d, I wanted to be able to do this for a robot I am making. I'm trying to put eyes which are just stretched out spheres. The thing is that the spheres go into the face insted of forming into it. I would love to be able to make the face solid and the eyes smash into the face insted of going though it.

I will try to post some images of what im talking about. If anyone here can picture what im talking about please reply, if im not very clear or just not making since please ask me some questions for me to explain it better.
Thanks in advance.

Yeah, you're asking for a sort of Boolean Displace function.
Its easy enough to calculate the volume to displace but the math involved in where to displace it gets a bit ott. Problem is you'd need vector to distribute the mass and force to control how far/thick to distribute it. ie All on one side or equally spread around and then whether thick/thin close or far spread.
Its a neat tool you're describing. It'd allow you to run a cartoon figure into a door and have it auto splat for you or a heap of other uses.
However, apart from manually as you said, I cant think how to do this in AC3D or in a bunch of other much more expensive programs.

Man I wished this was possible, I suck at trying to mold things like that.
Thanks for your response, maybe someone could and will make it.

Could you create an algorithm which would follow this pattern?:
1. Define object which will be collided
2. Define object to be collided with
3. Identify vertices closest to object to be collided with
4. Identify surfaces of TBCW object closest to immediate path of vertices
5. Move vertices in uniform direction until foremost vertices occupies same space as collided surface
6. Identify next vertices back
7. Repeat steps 5 and 6 as needed
Could this possibly lessen the workload a bit or work at all?

Me too, I just happened to go on another rant...
Sometimes I get lucky, though.
