Thought I'd post a challenge here to you John....or whomever...

 

I've been trying to get this effect but on a grid not a sphere .....to be exact I want , lets say a grid representing a piece of cloth or paper then the MAt Effect to start in the middle creating a hole then the hole to expand and burn away like U seen in the planet burning effect ..... or for a real world example for us old folks who remember Bonanza the TV series , that intro where I think its a map being burnt, tho that one I think starts from the side......just wonder how good (or not) my memory is......off to Utube....

 

I can so far get the hole in there and it to expand but with no burning away effect.

 

Thanks

About halfway down the page of Newton Physics examples are two projects that demonstrate a floating/bouyancy effect.

That might work better than material effects.

The projects have two movie files:

and here: http://www.hash.com/NewtonPhysics/samples/tugboat.mov

 

 

With regard to the second video where there is some 'sinkage', there is a tutorial (with link to project file):

Rodney,

 

Those are really cool. Thanks for posting those links.

 

I wasn't thinking so much along the lines of bouyancy with effectors. But rather how a

boat/ object interacts with the water plane as it bobbles through waves and moving surface.

 

I was thinking that maybe an effector could potentially fake a splashing wake as it plowed through

the water. Especially on a changing Water plane that has wavy movements.

 

Mixed with the newton stuff definately tingles even more possibilities for a neat simulation.

The effector could work for a stationary floating object but not for a boat that moved forward and turned, leaving a curved wake behind it.

 

Something I was experimenting with was using particles ejected horizontally from a moving shape to build a displacement map for the wave that is created as a boat moves forward and turns.
