breton_nerd, i use this version of ruby http://rubyforge.org/frs/download.php/47082/ruby186-27_rc2.exe for compile C++ extension.
And I comment lines
//#if _MSC_VER != 1200
//#error MSC version unmatch
//#endif
in c:\Ruby186\lib\ruby\1.8\i386-mswin32\config.h
I had failed with other versions. What version of ruby you use?

Don't forget that Blender has some great free render software too. Luxrender, Yafaray, POV, and others, though they are not working in 2.5 or 64 bit Blender yet. I just do my modeling in 2.5 and then export to 2.49 for rendering.

Yafaray for Blender 2.5 64bit
http://www.yafaray.org/phpBB3/viewtopic.php?f=12&t=3548

This code work:

 model = Sketchup.active_model
    faces = []
    faces.concat( model.entities.select{|e| e.is_a?( Sketchup;;Face ) }    )
    model.definitions.each { |d|
      next if d.image?
      faces.concat( d.entities.select{|e| e.is_a?( Sketchup;;Face ) } )
    }

thomthom, I run your code on Sketchup 7.1:

(eval);508; compile error
(eval);505; syntax error, unexpected tIDENTIFIER, expecting ')'
model.definitions.each { |d|
     ^
(eval);508; syntax error, unexpected '}', expecting ')'<<< Process finished.

I get DXF file, export from CorelDraw. Import into Sketchup.

Zoom-in.

How fix this problem? How to close the open circuit? What plugin would help?

What if you have a stone texture called 'lightgreymarble', will it become a light?

yes, It is temp solution.

Khai, You have to add light source. Create material with name contain "light" ex. "leftlight", "toplight", "mylight1" and assign to mesh.

Khai, do you open su2slg.skp or create own scene?

Hi.
SmallLuxGPU is GPU+CPU render.
About SmallLuxGPU

SU2SLG
Features:

• export ply-files, scn, cfg in "SLG folder/scenes/tmpscene"
• after export you can start render with start.bat
• default material type - 'matte'
• if material name contains 'light', then material type = 'light'

Unstable version. Tested on Windows XP. Not work on Mac.
Test scene attached.

Install.
Extract SLG-v1.5beta1.zip to folder.
Extract su2slg.zip. Copy su2slg.rb in folder "Plugins".

Any ideas you can post me exvion@gmail.com

Solution

 
require 'myplugin/Win32API'
LoadLibrary = Win32API.new("kernel32","LoadLibrary",["P"],"I")
path='' # set path to dir with dlls
dllname=path+'mylib1.dll'
LoadLibrary.call(dllname)
dllname=path+'mylib2.dll'
LoadLibrary.call(dllname)

I created mymodule.so. I put it in plugins/myplugin folder. Created myplugin.rb in plugins.
myplugin.rb

require 'myplugin/mymodule.so'

If I run myplugin.rb, I get a message box that is not found mylib1.dll and mylib2.dll.
How to specify where to find dlls?
Copying mylib1.dll and mylib2.dll in sketchup folder solves this problem, but I would like to specify the location of the directory with dlls.

How I can do it? Plugin?

TIG, thank. It is work.

Yes, this line is not correct, but I don't now how create face limited by two arc.
If I explode group, than I can generate face.

I created two arc

group = Sketchup.active_model.entities.add_group
vector2 = Geom;;Vector3d.new 0,0,1
group.entities.add_arc point0, vector2, vector, diametr/2, -150.degrees, 150.degrees
point0.z=point0.z-diametr*(3**0.5)*0.5
group.entities.add_arc point0, vector2, vector, diametr/2, -30.degrees, 30.degrees

How create face and push it? I try. What is wrong?

face=Sketchup.active_model.entities.add_face(group.entities)
face.pushpull distance,true

I don't know how calculate parameters of second arc.

I wrote
model = Sketchup.active_model
entities = model.entities
edgearray0 = entities.add_circle point0, vector0, radius
edgearray1 = entities.add_circle point1, vector1, radius

How make boolean subtraction?
