I'd like to draw a bounding box for my scene.
auto lambert = gl::ShaderDef().lambert().color();
gl::GlslProgRef shader = gl::getStockShader(lambert);
auto cube = geom::Cube().size(20, 20, 20);
m_boundingBoxRef = gl::Batch::create(cube, shader);
This draws a solid shaded box.
What I'd like to draw is just the edges, I'm guessing that there're might be a different shader I should use but I'm not sure.
Your help is appreciated.
