I recently put my 12000 vertcie''s model into a VB0 and it went from 16fps to 700fps. Obvisouly I want to keep it in the VBO so i was just wondering how and if you can alternate the memory inside the VBO in order to perform say animation. If this does not work does anyone know any good techniques?

What do u mean by alternate?

If it is switching to another array, just call glVertexPointer. If you mean modifying the data of the VBO, you cant do it directly but you can use STREAM/DYNAMIC to flag that data as dynamic and alter your array every frame/everytime u need to.
