Point Sprite

Hello in the current featured article, it says : "Point sprites were introduced in DirectX 8.0. They offer a nice advantage over the normal method of rendering particles. Normally you would create a rectangle using four view-aligned vertices set to the appropriate texture coordinates. With point sprites you can simply use one vertex for every particle! Therefore they require less bandwidth, so you can render more particles using point sprites instead of using the old method, and you don''t have to manually adjust the vertices to be aligned with the view vector." Is it possible to do the same in OpenGL (send one vertex for a particle) ? - Iliak -
