help

Hello, I would like to know how I can get the coordinates of the 8 corners of the "blue box" of a group or component that has been rotated and scaled

I tried to bounds.corner or local_bounds.corner but do not work properly for what I need, I have been looking and I could not find the appropriateness

.

thank you very much Thomas and Tig that prompt reply!

I will try to implement your suggestions right now

I wonder if there is any way to know the orientation of a group with respect to the axis of the world

@thomthom said:

Create a local transformation and apply with with .transform!( tramsformation ) instead of setting the .transformation matrix manually. Or am I missing something?

How to create a local transformation? I would like to see some sample piece of code to guide me

@thomthom said:

You mean, transform an object around its own axis and not world axis?

yes, exactly

Thanks for responding, I have helped a lot.

me a question arises about the transformations. if I need to apply a transformation to an object but not in the principal coordinate axes, but the coordinate axes of a group (rotated) what should I use?

(sorry for my bad English)

Hi, I'm trying to print a transformation matrix, I tried the following:

pointdd = Geom::Point3d.new 11,22,33 tdd = Geom::Transformation.new pointdd a = tdd.to_a text="-------------------------------------------------------\n" 4.times do |b| 4.times do |e| if ((e+1)%4==0) text << a[e*4+b].to_s+"\n" else text << a[e*4+b].to_s+" "+" "+" "+" "+" "+" "+" "+" "+" "+" " end end end text<<"------------------------------------------------------\n" UI.messagebox( text, MB_MULTILINE)

I wanted to hear suggestions of more elegant ways to do this. (I wrote several times +" " for failure to escrbir several spaces followed here)

thank you for your attention.

this is what I have achieved so far

entidad = %(#FF8000)[Sketchup]%(#0040BF)[.active_model.selection][0] curretmaterial = entidad%(#0040BF)[.material] nameM = curretmaterial%(#0040BF)[.name] curretmaterial%(#0040BF)[.color]=[102, 0, 51] curretmaterial%(#0040BF)[.name]=%(#BF8080)["nuevo tono"]

I shall be able then apply the recommendations

(sorry for bad English)

wow, is more complicated than I expected, I doubt that achieves do with my current knowledge of the Ruby API, I guess I'll have to wait a while thank you very much Dan, Tig and Thomthom for guiding me

here leave a lot of settings .visopt (I assume you know how to load them into vray)

is a bit late to answer but several people may be helped

I have another related question,

if I have a cube, each side painted a different color and then create a group or component, how I can access the list of materials the component or group to modify these materials from the code?

Would greatly appreciate a simple example of this, I could not find him anywhere

I have understood

mats = Sketchup.active_model.materials m = mats['jean blue'] m.color=[180, 0, 0]

I am new to this,that good there are good people willing to help, thank you very much Dan

(I know very little English)

thank you very much, functioned to change the display name

I looked at the API dictionary do not understand,
could you give me an example?
such as changing the color of the material 'blue jean' to red

Hello
I have a question
How I can edit a previously created materials? (from code)
and how I can change the display name?

thank you very much for the help, great links

%(#0040FF)[inserción de geometría en sketchup

Hola, estoy empezando con Ruby y deseo realizar un pluing para crear geometría con muchos polígonos (entre 3000 y 10000 polígonos) y he notado que se forma un cuello de botella en alguna parte del proceso de la inserción, porque cuando inserto 2000 polígonos se demora 1.5 segundos y al insertar 4000 polígonos se demora 6.1 segundos. Además solo he aprendido a usar add_face, que por lo que he leído no es el más eficiente, al parecer es mejor fill_from_mesh, pero no sé usar esto, agradecería que alguien me pudiera indicar como usarlo para el siguiente caso:]

(translation of gloogle)
Hi, I'm starting with Ruby and I want to make a pluing to create geometry with many polygons (between 3000 and 10000 polygons) and have noticed that forms a bottleneck somewhere in the insertion process, because when I insert takes 2000 polygons 1.5 seconds and inserting 4000 polygons it takes 6.1 seconds. Also I have only learned to use add_face, which from what I read is not the most efficient seems to be better fill_from_mesh, but I can not use this, be grateful if someone could tell me how to use it for the following case:

` # crear gaussiana con triangulos

entities = Sketchup.active_model.entities

n = 20 # size
s = 4 # separacion
w = 3 # tamaño de un elemento
b = n/2.0 # posision

(0..n-1).each { |i|
(0..n-1).each { |j|

  k=8.0*Math.exp(-((i-b)**2+(j-b)**2)/10.0)     # funcion
  face = entities.add_face [i*s,j*s,k*s],[i*s,j*s+w,k*s],[i*s+w,j*s+w,k*s]
  face.pushpull -w-k

}
}`

Para superar el problema del cuello de botella, pienso introducir la geometría por trozos, es decir en grupos de a 100 o 200 polígonos, pero no sé cómo hacer esto, agradezco su ayuda

To overcome the bottleneck problem, I will introduce the piecewise geometry, ie in groups of 100 or 200 polygons, but I do not know how to do this, I appreciate your help
