Not necessarily. Currently we have the same basic texture resolution everywhere. With the approach Sebastian wants to try one could use tiles of different sizes depending on the distance from the viewer. Which may or may not be a good thing but we won't know until somebody tries. > The point 2) is better except that this 100 pixel border is arbitrary. > Sometimes it will be ok but i'm afraid there is some triangles that will > go very far inside adjacent texture (some sea triangles inside the bay > are very long for example). There won't be triangles oriented along the bay. If I understood Stefan right, there will be a regular triangle grid depicting the elevation structure and the borders between different regions will be depicted by a change in the master texture. > But if the the real problem is those anoying triangle why not simply > delete them ?

Exactly. The question that comes to mind is whether OpenSceneGraph does not already have support for such a thing. The applications of OSG I have seen seem all to use this concept so maybe it is reasonable to believe s.th. like that has been included in OSG? Mathias? As I said I'm skeptical about the outcome, but I would say it's worth a try. Sebastian seems to be committed, so why not?
