ok, so im taking another stab at terrain rendering. im using geomipmapping. im using vertex arrays and triange strips for the rendering. ok so far. at the moment i have a vertex array at each leaf node with all the verts for that leaf. then i have several viewing levels stored as the index's to the verts to make the triangle strips. should i have a different vertex array for each LOD? id like to use VBOs eventually if that makes any difference. also are "indexed triangle strips" ( what i take to be the best method ) what im using? reading to many posts gets me very confused ;)

If you plan to use static VBO's then using the same vertices for each LOD will help reduce the video memory you use, but it's usually pretty hard to fill that up for most scenes anyway
