Hi, ive a few txt files which contains geometry, like: lines, triangles , quads, and matrices. Matrices reffered to sub txt files, which contains also lines quads tris and matrices.
i wrote my own loader class One txt file will be loaded in a geode. the loader runs recursively over all files and stored it in a vertex array Example: Code: geode =new osg::Geode(); geometry =new osg::Geometry(); vertices =new osg::Vec3Array(); colors =new osg::Vec4Array(); then i put the geometrie data in it osg::Vec3f vec[3]; // store geo in vector vertices->push_back( osg::Vec3 ( vec[0] ) ); vertices->push_back( osg::Vec3 ( vec[1] ) ); vertices->push_back( osg::Vec3 ( vec[2] ) ); colors->push_back (osg::Vec4 (1.0f, 0.0f, 0.0f, 1.0f)); colors->push_back (osg::Vec4 (1.0f, 0.0f, 0.0f, 1.0f)); colors->push_back (osg::Vec4 (1.0f, 0.0f, 0.0f, 1.0f)); finally : geometry->setVertexArray (vertices3.get()); geometry->setColorArray (colors3.get()); geometry->setColorBinding (osg::Geometry::BIND_PER_VERTEX); geometry->addPrimitiveSet(new osg::DrawArrays(osg::PrimitiveSet::TRIANGLES,0,triangles)); ... the problem is the performance and the memory if i load one file - okay but in case of many files > 30 i get a incorrect count of vertices ?? ( too much ) and the memory raised too much how can i improve the loader or is there a finished loader, which i can rebuild? Thank you!
