verts[0].Set (0, 0, 0);
verts[1].Set (10.0, 0, 0);
verts[2].Set(0, 10.0, 0);
Those vertices are directly on the plane of the camera. That means you cannot
see it. Try putting the z component a bit in front of the camera (like 1 or 2).
Additionally you didn't set up a material for this mesh. That's needed.
Greetings,
