Display error with strange face #113

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
I draw model in SketchUp (I use "Shapes" and "Push/Pull" tools). But when I 
preview with jsc3d, appearing strangers face. I try upload to sketchfab, it's 
ok.
You can see this attach, and OBJ file.
Help me, please

I think there are concave polygons 
(http://en.wikipedia.org/wiki/Convex_and_concave_polygons) in the obj model, 
which cannot be properly triangulated with simple triangulation algorithm 
currently adopted by Jsc3d.  Does SketchUp's obj exporter have any option to 
force the output to be convex polygons or triangles only?

I'm just looking for a good triangulation library that can be easily 
integerated into Jsc3d. This feature is definitely to appear in next release.

I try check triangulate all faces when export OBJ file, it's work. Thank you.
However, I'm not sure the other model are compatible. What time to next version 
will be release?

Just in a few days, I hope. It will be a plugin module like that for WebGL or 
multi-touch support.
