   What do we need 2D vertices for?
  Hi, I'm creating a library of classes for directx, and im tryin to decide if i still need the 2d vertice class. Like what would I really use it for if I have got the sprite class. Thanks,edit:Like i think the main disadvantage with vertices is that you can't move 2D vertices without reloading the buffer.[edited by - johnnyBravo on February 18, 2004 4:02:12 AM]
  There''s no such thing as 2D vertices.  I assume you mean Transformed vertices (x,y,z,rhw).Transformed vertices (being already in screen space) do not need to be transformed which in some cases could be a performance win.  Especially in the case of static items (your average HUD) there is no reason to transform them every frame if they never move.However, if sprites are working well for you there''s no reason not to stick with that path.
