Hello, I am trying to use a recursive function within a list comprehension to add some random component to both x and y coordinates of each point in a polygon (a circle actually). However I want each random component to be based on the previous random value in order to smooth the random component (and get some king of brownian/red noise).

Having x,y,z would be ok for me, but having all other details as rotations and scale wouldn't hurt. Some time ago I made a model of a IKEA-kitchen, that echoed a complete list of what I had put into my model.

Came across a Windy 26 for sale at a price that might just fit my budget. Realize it's not a MT 49 or anything but it might be a start as a one-person boat (no trans-ocean ambitions). Is there a web site where I might find more info? Any feedback on this vessel (1985 - bow thrusters-Volvo diesel-refridg for $56,900 CAD) would be appreciated.

A portion of my code, used many times, has the following segment: polyhedron( points = [ [cos(as)*Rroot, sin(as)*Rroot, z], //0 [cos(as)*Rtipp, sin(as)*Rtipp, z+z1], //1 [cos(as)*Rroot, sin(as)*Rroot, z+z2], //2 [cos(ae)*Rroot, sin(ae)*Rroot, z+zd], //3 [cos(ae)*Rtipp, sin(ae)*Rtipp, z+zd+z1], //4 [cos(ae)*Rroot, sin(ae)*Rroot, z+zd+z2

However the vertex data can be re-mapped (non-affine transformation), for example: points2=[ for(i=points) [i[0],i[1]+5*sin(8*i[0]),4*i[2]] ]; polyhedron(points2,triangles); Using a suitable mapping the text can be wrapped around a surface: r1=20; points3=[ for(i=points) let(a=1.7*i[0],r=r1+2*i[2
