generative modeling for Rhino
I am wondering if there is any way that I could define the maximum and minimum length of a spring? When the spring compresses to a certain length it does not compress any further, and the same with when it is pulled.
It seems like something that could potentially be defined somehow...
I'm thinking my original post was a little vague... I'll explain a little further.
I am building a truss system where each member of the truss will be a linear actuator. I will be using grasshopper, kanagroo and firefly. I ideally would like to manually adjust a node on the rhino model, and feed the data from the changes of lengths of the line into firefly. Firefly will then direct the arduino to move each linear actuator accordingly.
I have my model, and most of the grasshopper sketch (minus the firefly part). Now I need to figure out how to restrict the length of each of the lines of the truss since a linear actuator can only extend so far.
I hope I am clear..
Here is my simple rhino model and my current grasshopper sketch:
The way I would recommend to do this would be to actually use 2 springs for each member, one with a regular stiffness, and the other with a very high stiffness, and its LowerCutoff and RestLength both set to the max length you want to limit the spring to.
Thanks for the reply!
I tried out your suggestion (or I think i have tried it out) and it still does not seem to work. I'm sure that I am missing something; I've just started learning the program....
This is what I have got:
and I want to grab each point of the truss with my cursor and move it, like this:
thanks for all the help!
I have now got it working. Thanks again.
