Hi guys,

would something in the lines of this be hard to implement?
Basically the rope soft body but meshed instead of line rendering?

Or is there another way this kind of physics behavior can be achieved already with the existing features / puzzles / api?

Thank you,
Thomas

try to create a soft body (volume).

Puzzles and JS coding. Fast and expensive.

If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of the meaning at all.

Hi kdv,

thanks for the example and for pointing that out – i’ve tried soft body volume before, but as it seems, not with the right settings.
I gave it another try, and it works, it really seems to be the best option with the existing physics bodies.

A gradual falloff for the stiffness of the softbody isn’t possible, isn’t it? (Like a weightmap which controls the stiffness).

Why not? You can use animate param.

I rather meant parts of the mesh which are more stiff than others – not changing the stiffness over time… which i guess you meant?

Like the weight map on a rigged mesh which controls the amount of deformation on different parts of the mesh… but for the stiffness of the softbody allowing for more rigid parts and softer parts.

No.

But you may try a rigged mesh combined with physics.

I actually thought of a rig instead of the physics body – but i had the impression that a rig in verge3d can only be animated, but not modified in real time – through user input or physics.
