   3D terrain question (OpenGL)
  guys,i really need your help on this, do u guys knw/have any sample terrain editor source code in OpenGL? i want to learn how to make one, specially in rising/lowering the hieght of a certain location, dividing the terrain into cells/chunks, applying multi-texturing to it and applying LOD to it. I knw i have seen one around gamedev.net before(but its on dx) but i lost track of the link and forgot the right search keyword for it.If nothing can u point me to any URL that might help me implement one of the things above. I want to learn;a) How is terrain implemented in 3D RTS game including the common texturing technique used(splatting?). What is the algorithm commonly used (QUADTREE, Chunked LOD?)b)Is there any available book that really describe building an RTS terrain and implementing a Tile based texture to it? or a 3D RTS resource available on the net? (online tutorial, ebook or even online school with this course).c) On a texture splatting in a terrain. how to eliminate the "repetition" look of the tiles?
