What really? That's amazing Michael. Thank you!

@@benjaminf.3760 I am still teaching myself C# and specifically improving my skills in creating C# grasshopper custom user objects. I honestly found this video to be magical when I first started in Rhino and Grasshopper in the fall of 2018. Watching the video now, makes so much more sense and I am now able to bring the models into metal casting in my digital elective. Simulating and printing draped cloth is so beautiful in metal casting. Best, Michael

@@michaelwickerson4862 I'm very happy to hear that it had some impact on you Michael! If you learn C# I'm sure you checked out Long Nguyen's excellent tutorial series on RUclips?

I just did some tests on a much more simple mesh surface and realized the particles were falling through half of each face if it was a quad mesh. So the mesh has to be triangulated and then also the normals need to be flipped to face down away from the particles, unless it's a solid mesh, then the normals need to face out, which I don't understand why that's different.. just the way they have it setup I guess.

Hi Hammad, the component outputs the MSE of the training set after training. Getting the MSE of new test samples isn't implemented in a certain component, but can relatively easily be plugged together in GH... Cheers

@@benjaminf.3760 Oh okay thanks!!

Nevermind I saw your description! this is fun example to play with

@@tay.0 Hi thanks! Yes this is "standard" FlexHopper, although there are some components in use, that are only available in the latest release (only on Github so far).. I'll include the script in the next release as an example.. Cheers

@@benjaminf.3760 can't wait!

Hi Anas. Should be possible. You can change inflation parameters like pressure and volume during FlexHopper's simulation runtime. What these changes are based on is up to you....

Use a different group index then, one that is unique. Best B

@@benjaminf.3760 Same problem here, it's probably due to Rhino 7, this beautiful plugin needs an update

I'm facing the same issue

Hi Alessandro! Yes there is. Lock mode was replaced by the option Scene Mode in the FlexHopper Solver Option. When set to 0, current parameters are altered (like spring stiffness etc), when set to 1, new objects are added to the scene upon input change. When set to 2, no new inputs are considered for the sake of speed... Best Ben

@@benjaminf.3760 understood, thank you so much, if you don't mind I will ask again if I have other doubts :)

Hi Alessandro, did you make sure to really closely follow the instructions described here: github.com/HeinzBenjamin/FlexCLI#Instructions ...and that you have a dedicated graphics card that can run Flex (scroll all the way down on the github page to see the requirements)

@@benjaminf.3760 thank you so much for the fast answer...probably I have got a driver problem, I will try on my workstation at home, hope it will work

Hi there! So I'm basically using a library provided by some researchers. It's called CycleGAN and you can find it here: github.com/junyanz/CycleGAN Now this library does all the complex computation. It's written in a programming language called Lua and only runs on Linux-based systems via another software (a machine learning framework) called Torch. What I did in this example is to automate CycleGAN. To do that I set up a linux machine on a remote server. on this linux machine there's a little shell script monitoring a specific folder on the linux machine. whenever a new image file appears in this folder, the shell script runs CycleGAN and performs the image processing on the newly discovered image. when it's ready it drops the processed image in another specific folder. the second part is a script running in rhino that takes screenshots every now and then and stores it on a certain folder on the windows machine. through another little program called WinScp the folders on the windows machine and the remote linux machine are synced. So whenever the rhino script takes a screenshot and saves it to the hard drive, winscp send it to the linux machine, where my shell script is listening to incoming images, when it receives something it processes it through cyclegan and stores it in another folder. this "output" folder is monitored by WinScp. So when CycleGAN produced a new image, it's send to the windows machine via WinScp. On the Windows machien there's another Grasshopper script checking if a new CycleGAN image was received. If yes, it displays it on the canvas. So my part had actually very little to do with establishing a GAN algorithm. I just automated what's already there. Hope that clarified a few things. All the code is public here: github.com/junyanz/CycleGAN (core GAN library) github.com/HeinzBenjamin/CycleTraffic (my automation)

Hello. Unfortunately that's not possible. The reason is that the internal Nvidia flex engine doesn't allow access to force values. So there's no way for me add this functionality. You can change velocities but no forces

Thank you Benjamin！ One more question, is it possible to constrain all the particles in one plane? I've tried to create a gap (two plane constrain) and put the particles inside the gap, but the particle can still escape.

I'm trying to do some planar linkage movement simulate using fluxHopper :)

@@ltlitetools6975 hi! Sorry for the late reply. Yes the approach with two planes should work. Make sure that they are facing each other and don't face in the same direction. Also make sure that the gap is larger than zero and that your collision distance is smaller than that gap size..

@@benjaminf.3760 The velocities are set for the systems initial state, or is it possible to change the velocity of particles individually and dynamically, according to a vector direction?

Sorry the code is not open source

Good question, I actually haven't tried that! If I get around doing it I'll make sure to post it here.... If you want to try it yourself check out github.com/junyanz/CycleGAN and my (rather buggy and crappy) automation code for rhino github.com/HeinzBenjamin/CycleTraffic

Hey sorry I'm afraid I don't have time for this atm. There are a lot of Grasshopper tutorials out there though... the existing Flexhopper tutorials might get much clearer once you mastered Grasshopper

yes that's possible. the bottle needs to be a mesh geometry that you add into the collision geometry. then all particles should collide with it. then you'll need to define your falling objects. use e.g. the rigid body component. there are FlexHopper tutorials on my channel for all of that...

Thanks a lot for your answer!!! I hope i will be able to do it because the tutorials for this are extrem rar what i found so far, seems like to be a secret how to work with grashopper :-)

Are you gemran? Because your name. Would make it easier maybe to communicate :-)

MaxD hey. Check out the latest version of flexhopper on food4rhino. The example files should more or less all be there

Hey Benjamin, I found the files. Thanks for you fast reply!
