 I'm trying some other solution here, I suspect that this model is already simple enough and no triangle can be removed somehow without changing the shape.... 
I need some topological structure where I can query for adjacent triangles of a vertice / triangle or adjecent edges of a vertive / egde.. is there anything like this in cgal.. (I think there is).. any one can give-me an example or a doc about some structure like this? I'm currently using a CGAL Polyhedron to store my triangles... Can I pass this to any function to build the topology I want?


thanks!!!

Fernando, thanks for all help,
you might want to take a look in my model, so I've built a single viewer that opens the model (model an executable must be at the same place)... if you press 'w' the model comes to wire frame and you can see the unwated edges.. if you press 'e' the model become filled.... You can manipulate it using the mouse... its like an examiner.. if you drag using the right button it zooms...


the model is rendered using only independent triangles... and it has several blocks, it is not a single model itself, it is composed by about 10 parts (10 objects placed in the world on over other..) but I dont think it has anything to do with the problem.. I don't know.. because its all about triangles I've pushed into the Polyhedron....

anyway...

It might help...

thanks!

Sure, I've saved my polyhedron to a file using the stream operator of the Polyhedron class, I'm sending it with a cpp file which opens it and runs the default simplification.. thanks!

Hello Pablo,

Can you post a short program that I could compile and test myself?

That means that if the mesh has less than 1000 edges, none will be removed.
Your mesh has more than 1000 edges right?

Best
