WaveFront File importer on Pharo

Jean Baptiste Arnaud
Hi, 
Under the pressure of Camillo i publish the code.
I beginning to do a Wavefront (human readable standard for 3d Obj Model ) importer on Pharo.

So i made a importer.
Not all the case are manage, only the case I need to import the current Obj model.

And a drawer which is in Alpha version.
face and normal vector are manage.
Missing color (in progress), and texturing.

You need .obj file and all the .mtl related (open you blender and make it nice).

If you are not running on Mac os comment this code in GLWorldTest>>#render, the 

display makeCurrent.

else if you running on mac os implement it in 
NBMSAAOffscreenDisplay>>#makeCurrent 
^driver makeCurrent.

My code can be find on JBARepo on squeaksource 
ObjModel Package but you need NBOpenGL (i do a configuration in same place i just need to be motivated for keep it up to date).

So 
put on same folder of the .image your .obj and .mtl file (i am lazy) (maybe it is VM folder i do not know).
open a workspace and do

"s := ObjImporter importFrom: 'xwing-map.obj'.
s parse.
object := s objects.

w := GLWorldTest new.
object do: [:e | w addElement: e].
w openInWorld."

3d result with normal 


With normal and color but not texture : 


Enjoy




Best Regards
Jean Baptiste Arnaud

I have transparency now and i beginning texturing.
I just need to check the rule for drawing to be more accurate with .obj model (basically change to parameter and take the best result).
I need to parse and to rewrite all the path for texture it did not find (every texture in fact, blender export in a really strange way). 
And in addition there are plenty of different kind of texture and I need to learn OpenGL. :-)
i already success to texturing the vador starship. I need to generalise process now.

Hi JB,

 Excellent!
 I tried to give it a try for the fun.
 I couldn't make it work.
 
 I updated some stuff (find it attached):
 - ConfigurationOfObjModel-LucFabresse.2.mcz
    added repository for package OBJModel in baseline
 - OBJModel-LucFabresse.7
    add support for empty lines and "g" lines in wavefront format parser (ObjImporter>>dispach:)
 
 Here the snippet I tried:
 
filename := 'teapot.obj'.
response := ZnEasy get: 'http://people.sc.fsu.edu/~jburkardt/data/obj/',filename.
(FileSystem disk workingDirectory / filename)
writeStreamDo: [ :stream | stream nextPutAll: response contents].

s := ObjImporter importFrom: filename.
s parse.
object := s objects.

w := GLWorldTest new.
object do: [:e | w addElement: e].
w openInWorld.

Parsing seems to be ok.
But, creating the GL context failed: invalid pixel format.
On a mac OSX 10.6.8.

I am eager to play deeper with that ;-)
