very interesting!, could teach how to do this with php?
and show some code?

the helix is closed properly!

if I want to Vray in only one computer, I am forced to buy the dongle?

I did not understand point.offset, with this example I understand a little more, thank you very much Thom, very interesting this

I thought of a way to put the plane in the format [point, vector], at some point it might be useful to someone

p1 = Geom;;Point3d.new 1,1,1
p2 = Geom;;Point3d.new 2,1,1
p3 = Geom;;Point3d.new 1,2,1
p4 = Geom;;Point3d.new 1,2,0
pl = Geom.fit_plane_to_points p1, p2, p3, p4

tolerance = 0.0001
if pl[2].abs > tolerance
   point = Geom;;Point3d.new(0,0,-pl[3]/ pl[2])
elsif pl[1].abs > tolerance
   point = Geom;;Point3d.new(0,-pl[3]/ pl[1],0)
else
   point = Geom;;Point3d.new(-pl[3]/ pl[0],0,0)
end
vector = Geom;;Vector3d.new(pl[0],pl[1],pl[2])

plane = [point,vector]

thank you very much Dan, is exactly what I needed

thank jolran, that's not my next step, but I thank you, I had not seen the command project_to_plane

Hi guys, I'm trying to adjust hundreds of points to a plane, my problem is that I do not understand the output format fit_plane_to_points, I expected a Point3d and Vector3D, but it seems I get different, I do not know how to interpret the result, appreciate the help in advance

point1 = Geom::Point3d.new 0,0,0 point2 = Geom::Point3d.new 1,2,3 point3 = Geom::Point3d.new 5,5,5 plane = Geom.fit_plane_to_points point1, point2, point3 plane.size

In my opinion there are several things that are doing well in Trimble
But I see a couple of errors:

1. when opening sketchup 8 will not get a notice to upgrade to 2013 version (because of this, they will lose millions of users)

2. in "Sketchup 2013 free" entities transformations performed more slowly than "Sketchup 2013 pro" and "Sketchup 8". These things are really serious errors

made with helix along curve

How is configured by default "Sketchup 2013"?
I've noticed that changing this setting has strong effects on plugins that provide some kind of animation.
In Sketchup 8 an option that works best for me, is as follows

I do not know how it is in 2013

hi, I ask how I can remove a layer from ruby, I could not find a way to do this,
thanks in advance

I see that lens effects have been added, thank you very much for adding this!

thank you very much for the replies dan and Thomthom, I'll take a look at the code Thomthom experimental, to see if I can use some of this code

(google translator)

Thanks for the tips Thom, this will be very useful at some time

I have a question, how can get the vertices of this surface?

!woooow this reduces the time to less than one-third!

thank you very much Daniel!

this console is wonderful that good to continue to improve
for now I just watch a possible error in the syntax highlighting when I write something like this;

n = 100
periodos = 20
c = Math;;PI*periodos/n
ve=[]; ve_inv=[]; vectors=[]; vec_invert=[]
for j in 0..n
   Math.sin(c*j)
end

Hi guys, I want to ask if there is something faster than add_polygon, I see much difference when I commented the lines 15 and 16. with this pair of lines becomes 130 times slower!
seems that the command "add_poligon" does something very complicated or is very inefficient or I'm using it in the wrong way
in the following code I make a rectangle subdivided;

t = Time.now
lados_x = 100
lados_y = 100
mesh = Geom;;PolygonMesh.new((lados_x+1)*(lados_y+1),lados_x*lados_y)
l1 = []
for i in 0..lados_x
   l1[i] = Geom;;Point3d.new(i,0,0)
end
l2 = []
for j in 1..lados_y
   for k in 0..lados_x
      l2[k] = Geom;;Point3d.new(k,j,0)
   end
   for i in 0..lados_x-1
      #mesh.add_polygon l1[i], l1[i+1], l2[i+1]
      #mesh.add_polygon l1[i], l2[i+1], l2[i]
   end
   l1 = l2.clone
end

=begin
ent=Sketchup.active_model.active_entities
grupo = ent.add_group
entities = grupo.entities
entities.fill_from_mesh mesh, true, 0
=end

Time.now-t

Does anyone have any suggestions?

you sent me on the right track, thanks sdmitch
