greetings all –
anyone heard of a script that can create a cloud of vertices according to an array of mesh objects?
What I need to do ideally is to take an array of objects that I’ve laboriously arranged in 3d space, and generate a Mesh object who’s vertices would correspond directly (position and normal orientaion) to the pivot point of each object in the array.
so basically generate an independent vertex for each object in the array according to pivotpoints, and then generate a trangulated mesh that links together all these free-floating points (according to their proximity to one another along one axis, i would guess, not being scripter myself)
finally I’d want to link each one of those objects in the array to its corresponding vertex and then deform that derived mesh without disturbing the geometry of any of those array objects ala SurfaceFollow feature. Think dragon skin!
any ideas?
big thnx

Well, I don’t think its all that easy…
I tried something, that only really works with 4 points…
It builds a mesh with a vert on all objects, but more objects and the way to extract faces from that is very difficult…
I tried
-- Sort Function
fn sortclose v1 v2 =
(
dif = v1[2] - v2[2]
r = case of
(
(dif < 0.): -1
(dif > 0.): 1
default: 0
)
)
-- Get Closests objects in selection
fn closest obj sel =
(
distArr = for o in sel where o != obj collect #(o, (distance o obj)) -- Build array with node and distance arrays
qsort distArr sortclose -- Sort it
format "%
" distArr -- Debug
f1 = findItem sel obj -- Get Node place in array to determine vert nr
f2 = findItem sel distArr[1][1]
f3 = findItem sel distArr[2][1]
point3 f1 f2 f3 -- Return a point3 with face/vertice reference
)
-- Script
s = selection as array -- Get Selection
objs = for o in s collect o.name -- Make name array for sorting
sort objs
s = for o in objs collect (getNodeByname o) -- Rebuild ordered obj array
verts = for o in s collect o.pos -- Get new Vert positions
faces = #() -- Collect faces in here
for o in s do
append faces (closest o s)
mesh vertices:verts faces:faces -- Build mesh object
If someone can take it further I’d be very interested.

*edit: changed a small mistake in the script
Some modifications… link all objects to their vertice
-- Sort Function
fn sortclose v1 v2 =
(
dif = v1[2] - v2[2]
r = case of
(
(dif < 0.): -1
(dif > 0.): 1

)
)
-- Get Closests objects in selection
fn closest obj sel =
(
distArr = for o in sel where o != obj collect #(o, (distance o obj)) -- Build array with node and distance arrays
qsort distArr sortclose -- Sort it

f1 = findItem sel obj -- Get Node place in array to determine vert nr
f2 = findItem sel distArr[1][1]
f3 = findItem sel distArr[2][1]
point3 f1 f2 f3 -- Return a point3 with face/vertice reference
)
-- Script

sort objs
s = for o in objs collect (getNodeByname o) -- Rebuild ordered obj array

for o in s do
append faces (closest o s)
m = mesh vertices:verts faces:faces -- Build mesh object
c = 1
for o in s do
(
s = position_script()
script = "GetVert m " + c as string
o.position.controller = s
s.addNode "m" m
s.script = script
c += 1
)
/*
for obj in selection do obj.position.controller = position_XYZ()
*/
