Hi (Robert :) I've tried a lot of things to get osgText working on MacOSX with VAO. GL3 on OSX Core Profile requires VAOs.
osgText doesn't setup the VAO path correctly on MacOSX. I can show glyphs when I use a osg::Geometry as a Wrapper to draw geometries from text glyphs like so: Code: class ExtText : public Text { friend class VAOText; }; class VAOText : public osg::Geometry { private: osg::ref_ptr<ExtText> _t; ... void redraw() { unsigned int contextID = 0; // renderInfo.getState()->getContextID(); if ( !_t->_textureGlyphQuadMap.empty() ) { const ExtText::GlyphQuads& glyphquad = (_t->_textureGlyphQuadMap.begin())->second; if (!glyphquad._transformedCoords[contextID].valid() || glyphquad._transformedCoords[contextID]->empty() ) { _t->computePositions(contextID); } } for(ExtText::TextureGlyphQuadMap::iterator titr=_t->_textureGlyphQuadMap.begin(); titr!=_t->_textureGlyphQuadMap.end(); ++titr) { const ExtText::GlyphQuads& glyphquad = titr->second; const ExtText::GlyphQuads::Coords3& transformedCoords = glyphquad._transformedCoords[contextID]; if (transformedCoords.valid() && !transformedCoords->empty()) { setVertexArray(transformedCoords.get()); setTexCoordArray(0, glyphquad._texcoords.get()); getOrCreateStateSet()->setTextureAttributeAndModes(0, titr->first.get(),osg::StateAttribute::ON); addPrimitiveSet(glyphquad._quadIndices); } } } But it doesn't work with plain osgText. So something is wrong in osgText / VAO.
