Physics Engine for Rhino

Good evening folks,

I find this forum the most relevant for my question. There is an integrated physics tool in 3ds max which allows you to make realistic courtain, matress, pillow, blankets etc that you can manipulate in order to give a realistic results based on real-time physics and manipulation by the user. Is there anything alike for Rhino? Would we expect something like this coming to life within Rhino 5 lifecycle?

I know Rhino is more of an architectural design programm and not for animation, but i am sure real time physics for cloth objects is very VERY important in production rendering.

Everyone who is using Rhino / v-ray is coming against this issue and it would be usefull to be able to create as much realism as possible.

Thank you in advance.

Yes, Kangaroo already exists but is a bit eccentric on purpose, and sadly not open source yet:

A minor issue here is that Grasshopper will be updated soon from 0.9 all the way to to 2.0 to then match 3D Studio Max in sophistication, which indeed has some old school "math engine" DNA, but alas no more metaballs like once it did.

Kangaroo now has two versions, a work in progress.

Yeah, it does all that stuff, with examples being posted in this forum, along with numerous updates spawned by user comments. Tell the developers of Kangaroo and Grasshopper more in detail what you need, please.

As Nik said.

Plus: try Modo as well (straight from the US movie industry, some parts to be accurate, he he).

Hi Dim,

Yes, Kangaroo is a plugin I develop for Grasshopper which allows simulation of physics.

It was originally created for different applications than the typical engines in rendering/animation software - with more emphasis on structural form-finding and geometry optimization for engineering and construction (calling it 'eccentric on purpose' rather misses the point!).

It does also now have the capability to simulate cloth draping over objects and colliding with them and itself though, like in your examples, but this isn't an application I've worked on much, so there aren't currently a lot of prepared examples. I can see how this could be useful though, and I'll have a go at setting something up to make it easier to do the kind of things you show in your links.

Thank you both for your replies.

Daniel i will take a look in Kangaroo Physics and figure this out myself. Keep in mind that cloth physics like pillow/matress/bedsheet/curtain simulation have to be casual and user-friendly. The user who is only interested in making photorealistic interiors and exteriors might not be interested in parametric design in generall. It has to be straight forward for users that have little or no clue with Grasshopper and/or Kangaroo Physics.

It would be hard hard for a new user to combine unary force. gravity and strings commands that enter kangaroo physics command as inputs in order to make a pilow. He would fail big time. I would suggest that you include an "entry" command(could be named Cloth Physics Command) that would do the cloth physics standalone or as a single input to Kangaroo Physics command that would work like in the videos that i linked.

T might be asking too much, but that would be a great feature for casual rhino users overall.

Thanks
