Daniel, We need to see what drawLines( tri, 0 ) is doing.

So I'm drawing several triangles on my scene. here is the code that draws the first 2. I'm reusing the first same geode. The strange thing is that the 'right triangle' is a different color (black) than the 'left triangle' (light green) I'm actually drawing 2 others and they are black too. I need them to be green. Can anyone tell me what I'm doing wrong? It makes no sense to me. Danny osg::Vec3Array* tri = new osg::Vec3Array; tri->push_back(osg::Vec3(0.0f, -0.1f, depth)); tri->push_back(osg::Vec3(0.1f, 0.0f, depth)); tri->push_back(osg::Vec3(0.0f, 0.1f, depth)); osg::ref_ptr<osg::Geode> triangle = new osg::Geode(); triangle->addDrawable( drawLines( tri, 0 ) ); // right triangle { osg::ref_ptr<osg::MatrixTransform> translate = new osg::MatrixTransform; osg::Matrix tran_mat = osg::Matrix::translate( hud_aspect, 0.0f, 0.0f ); translate->setMatrix( tran_mat ); osg::ref_ptr<osg::MatrixTransform> rotate = new osg::MatrixTransform; osg::Matrix rot_mat = osg::Matrix::rotate( M_PI, 0.0f, 0.0f, 1.0f); rotate->setMatrix( rot_mat ); camera->addChild(translate.get()); translate->addChild( rotate.get() ); rotate->addChild( triangle.get() );; } // left triangle { osg::Matrix m; osg::ref_ptr<osg::MatrixTransform> mt = new osg::MatrixTransform; m.makeTranslate( -hud_aspect, 0.0f, 0.0f ); mt->setMatrix( m ); camera->addChild(mt.get()); mt->addChild( triangle.get() );. } Classification: UNCLASSIFIED Caveats: NONE _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
