Hi, I do an update on this topic, because I would like to understand well the osgUtil::simlifier. This implementation seems to be very complex and powerful, but I don't know how to manage it better. /For that I would like to know what do the following methods and how to set the values to

Hi Andrew Thanks for the tip on the simplifier, lower the sample ratio is, lower the vertex number is. (I get a crash under 0.6 but I'm not sure this is an osg crash) Concerning the optimiser, this do not reduce the vertex number but the inverse... on a 460k vertices model, the optimizer returns

Up ? No one does osg simplifications ? Thanks, Vincent. 2009/9/17 Vincent Bourdier vincent.bourd...@gmail.com Hi all, Using the osg simplifier on a geometry, I'm just surprised to see that there is no way to set a level of simplification or something like that. Maybe I didn't saw it,

Hi there, I've experimented with the simplifier, but am not using it. I found the setSampleRatio() method affects how coarse or fine a result you get. The simplification with a sample ratio less that 1.0 appears to be destructive (i.e. Geometry out does not equal Geometry in). So far I've not
