inal surface, creating buckling.

I experimented with many different texture effects. In the end I decided i liked the idea of the outer surface being eroded smooth. With the articulate texture protected within folds.

closest point to the very first would be removed from the list, so the initial list reduces from 100 to 98. From the 98 i pick one and search the remaining 97 for the closest. From the remaining 96 i pick again one and search in the 95,...
(The product I want to result is:
having a number of random lines in 3D space, produced by an even number of points as discribed, this shall be the initial springs for a ("selfadjusting") tensegrity. Each one of these lines (later springs in kangaroo) get divided in three areas - that means four points. These four points again are the "attractor points" of neighbor springs, so the strut "knows" where to set the next elastic connection,...the rest I´ll have to figure out)

A low-resolution work. Real time motion capture display made with an 11x8 (88) pixels iPad matrix using Grasshopper + Firefly + Pure Data + TouchOSC for iPad.
ase to give the same result using a graph mapper with a parabola as in the attached file
Unfortunately it never gave the same result ..... is it a mistake in the book ?!…
moved by random amounts in a random direction. The animated slider was the amount of deviation from the original points. And yes, I used culled lists.B.t.w. did you find my workaround for your loft? Did your notebook explode? ;)…
am doing the paneling tutorial from the first primer..pg 88. i baked it but while selecting the multiple geometries i cannot select individual ones, they are selected as surfaces..is that ok or .....?

exact formula is inside /lib/skybright.cal if this can help you to find the name.
{ RCSid: $Id$ } { Sky brightness function for sunny and cloudy skies.
Additional arguments required for calculation of skybright:
A1 - 1 for CIE clear, 2 for CIE overcast, 3 for uniform, 4 for CIE intermediate A2 - zenith brightness A3 - ground plane brightness A4 - normalization factor based on sun direction A5,A6,A7 - sun direction }
cosgamma = Dx*A5 + Dy*A6 + Dz*A7;
gamma = Acos(cosgamma); { angle from sun to this point in sky }
zt = Acos(A7); { angle from zenith to sun }
eta = Acos(Dz); { angle from zenith to this point in sky }
wmean(a, x, b, y) : (a*x + b*y) / (a + b);
skybr = wmean((Dz+1.01)^10, select(A1, sunnysky, cloudysky, unifsky, intersky), (Dz+1.01)^-10, A3);
sunnysky = A2 * (.91 + 10*exp(-3*gamma) + .45*cosgamma*cosgamma) * if( Dz - .01, 1.0 - exp(-.32/Dz), 1.0) / A4;
cloudysky = A2 * (1 + 2*Dz)/3;
unifsky = A2;
intersky = A2 * ( (1.35*sin(5.631-3.59*eta)+3.12)*sin(4.396-2.6*zt) + 6.37 - eta ) / 2.326 * exp(gamma*-.563*((2.629-eta)*(1.562-zt)+.812)) / A4;
