STL triangle mesh simplification

SunHongLei's picture

Hi,there. I am working on a model of processing STL data. I have a problem:
In order to show a stl surface rapidly, I need to decrease the number of triangle mesh .For example, I have a STL file which contains 1000 triangle meshes but I only want 500 triangle meshes. How can I do with this problem?
please help me!

Hi, I have now the same problem. Is there a methode, that
use edge collpase for mesh simplification? Does somebody know
,if there is an example for that?

Thank you in advance

OCC is oriented in dealing with BRep data ( higher order geometry ), so I guess best to look for something like VTK or meshlab, that are more oriented towards dealing with triangle soup.

VTK would be the best solution, beacuse of the BSD license.
Thank you again
