distance from point to surface with sign
3 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

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

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

Joseph Oster replied to riccardo foschi's discussion distance from point to surface with sign
"Make an post a GH model! Measure the angle between the normal vector and the 'Vec2Pt'.  If it's at (or near) zero, the sign is positive.  If it's at (or near) Pi, the sign is negative. P.S.  What Daniel said works…"

"thanks! it would be useful to have a toggle to make all this calculation at once in the "surface closest point" node"

Daniel González Abalde replied to riccardo foschi's discussion distance from point to surface with sign
"Being 'N' as the normal at 'cPt' on surface and 'V' the vector from cPt to Pt, if the dot product of N and V is positive, then Pt is above, if not is below the surface."
