### Angle between 2 rotating vectors2 Replies

Hi guys, I would like to calculate the angle between 2 moving vectors see the attached figure.but if I use the angle node obviously it gives me always the smallest angle in the "angle output" and the…Continue

### Brep intersection node2 Replies

Draw two identical cone (without capping the circular base) and rotate randomly one of the two cones around his top vertex in a way that the two cones stil intersect.Now trying to apply the brep…Continue

### distance from point to surface with sign3 Replies

Which is the simplest way to have the distance from a surface with sign depending on the normals of the surface?I tried the "surface closest point" node but it doesn't have the sign.Continue

### chose the direction of the edge in the triangulate mesh node7 Replies

Hi all, in both  rhino and grasshopper is there a way to control the direction of triangles when using the command triangulate mesh? I noticed that he always choose the shortest diagonal of the…Continue

Hi guys, I would like to calculate the angle between 2 moving vectors see the attached figure.but if I use the angle node obviously it gives me always the smallest angle in the "angle output" and the biggest in the "reflex output"how can I get the anglee seen in figure as output without switching manually between the reflex and…See More

### Brep intersection node

Draw two identical cone (without capping the circular base) and rotate randomly one of the two cones around his top vertex in a way that the two cones stil intersect.Now trying to apply the brep intersection node it wont works.It works only if the tip of the two cones are not in the same exact place, or if you trim the top point of at least one cone. Probably is a limit case which has not been considered.Was it a known bug?See More

"I have another question about kangaroo working: which is the highest number we can be input in the stiffness variable?I observed that when we exceed a certain value nothing changes in the result.So I'm wondering if there is a value which…"

"Hi David, Could you explain a bit more why you lowered the whole graph by pi/2? Wouldn't 0, pi, and 2*pi angles be sufficient solutions? Or due to the interpolation we wouldn't have intersections at the two limits? I'm confused…"

"Hi Riccardo, The solver in versions of Kangaroo before 2.0 was fairly standard dynamic relaxation (along the lines described eg by M.R. Barnes in his thesis). In Kangaroo 2.0 and later the solver method is still similar to dynamic relaxation,…"

### Kangaroo working

Hi, I'm writing a paper on an algorithm involving Kangaroo, so I would like to investigate more in depth how kangaroo does works, is there some sort of documentation about the phisical rules which are used inside nodes and what does stiffnes and other similar input parameters means in terms of Phisical formulation in each node?Thanks in advance, RiccardoSee More
