Collision with Kangaroo

Hi all.I tried to use Kangaroo to make a phisics interaction between 3 meshes. These ones interact correctly with the box, I can not do meshes interact with each other (as you can see in the…Continue

Nesting algorythms resources?

Hi forumI'm writing a script for nesting a series of rectangles in a sheet of metal, ready to be cutted with laser or CNC. Anyone of you have some hints or links about nesting algorythms?Thanks in…Continue

I uploaded a Grasshopper definition useful when you had to dealing with tube bending machine. It extracts the coordinates af a tubolar frame in a csv file. With little efforts you can custom the code…Continue

Daniel,
I tried to put on mass and velocity in two different particles, then went to add new strength to the collision and interction with them. Some drawings made the trail look interesting! The biggest problem I found was to put new entities that…

Paolo,
I made a circule using a esphere...and one force!
It was my start..

Thanks Paolo,
I caught a few examples in user groups pages, put themto work and try to modify it to my goals, but it is hard work!
;)

Thanx Daniel for you replay
I'll trying to put on mass, velocity, acceleration and a path to the particles. I'll simulate people escaping through a door or stairway in a subway station. I'll put the particles in a box, and measure how…

I haven't tried full collision detection (edge-edge, edge-face etc.), and don't plan on doing so soon, for reasons i mentioned here (http://www.grasshopper3d.com/xn/detail/2985220:Comment:147114)
I think just responding to vertices…
Paolo Cappelletto replied to Paolo Cappelletto's discussion 'Collision with Kangaroo'
No problem Daniel, it was only a test, I imagined something like that
but I have a curiosity, I would like to test the intersection beetwen a edges and face of the meshes to detect collision. Have you ever tried something like this?
Daniel Piker replied to Paolo Cappelletto's discussion 'Collision with Kangaroo'
Hi Paolo,
At the moment collision is only for particles with static Breps.
I have implemented what I think should work for dynamic mesh/mesh collision, but it relies on a feature in the Rhino SDK that currently seems to have a bug which is…
Paolo Cappelletto replied to Paolo Cappelletto's discussion 'Collision with Kangaroo'
you can find tutorials on the kangaroo user group pages.
You must have a brep that works as collision object, or you can set an uniform space (a sphere around a point) that works as collision space.
I didn't receive any feedback about this post…

Do you have some tutorials for colision problem?
I've problems toacelerate particules...
Thanx

Hi Paolo.
Real waste mainly depends on the shapes you intend to process :
many voids or Ushapes generates lots of waste.
Have a nice weekend... Bye

Hi Stanislas
first of all thanks for all your hints, very very complete. Now i got something to read for the weekend ;-)

you're right, but…
