Knot around a pipe: missing something

[nachetz]

Hi,

i’m missing something to make this work, i don’t know why Kangaroo skips the collision with the cylinder.

knot_cylinder.gh (15.2 KB)

Could anybody tell me what am i missing?

Thanks in advance

If you change the strength it does not pass through the cylinder:

knot_cylinder.gh (34.6 KB)

You can also offset the solid outwards by the radius of the rope first to account for the thickness in the collision.

Also, if the obstacle it is wrapping around is always a cylinder, it could even be done without the SolidPointCollide goal, by including the cylinder as another line segment input to the Collider, with a different radius.

thanks a lot Daniel!

i see i also missed “rod” slides scale, values were too high

Thanks again. Hope to make good use of your help, this image was made in a classic way, hope to improve with Kangaroo
