Hi Everybody,

I was wondering is somebody already tried, or may have an idea of how to proceed to “melt” an object . I'm not asking for a howto, but just trying to collect some ideas

Thanks in advance,

Julien

well you could build your object with metaballs, which then can easily be ‘melted’, just an idea

Another method: you could flatten your object in UV space, send some noise through and clip, unflatten object, now you've got some ‘melting/burning’ going on, take the burned geometry and use as softbody basis for example.

Ok one more, you could create a melting effect with your shader rather then geometry. Check out this paper:

Jos Stam, “Flows on Surfaces of Arbitrary Topology”, In SIGGRAPH 2003 Conference Proceedings, Annual Conferences Series, July 2003

It's a good starting point.

Any body else any suggestions?

How does that paper help with melting an object? I would imagine that if you were to do it with shaders, it would be some sort of displacement shader at the very least?

Edward,

I would imagine that you set the opacity based on the flow that has passed, but I haven't tried it out yet, since he just wants a few ideas.

Thanks for the ideas ! I think I'm going to try with some displacement & soft bodies
