Hi Pietro, You need to pass in the number of vertices to draw to DrawArrays.
I'd also recommend not using per vertex indices as this force the OSG onto OpenGL slow path, its best to use DrawElementsUInt/UShort instead. Robert. On 4/23/07, Pietro Incardona <[EMAIL PROTECTED]> wrote:
Hi all I am trying to draw a line starting from a vertex array and an index array I have tryed a code like this: .................... Lines.index->push_back(n1); Lines.index->push_back(n2); Lines.colors->push_back(osg::Vec4d(1, 1, 0, 1)); Lines.EncLines->setVertexArray(Points.Points.get()); Lines.EncLines->setColorArray(Lines.colors.get()); Lines.EncLines->setColorBinding(osg::Geometry::BIND_PER_PRIMITIVE); Lines.EncLines->addPrimitiveSet(new osg::DrawArrays(osg::PrimitiveSet::LINES, 0, Lines.index->size() / 2)); Lines.geode->addDrawable(Lines.EncLines.get()); .................... Points.Points.get() is a Vec3Array containing n vertex Lines.colors.get() is a Vec4Array Lines.EncLines is the geometry Lines.geode is the geode n1 and n2 are 2 index Lines.index is a UIntArray don' t draw nothing the method is correct ? Is there another method ? _________________________________________________________________ Ami i Quiz?
