after models, i moved on to rendering WoW's terrain. terrain in WoW is stored in chunks called ADTs, which are fixed mesh grids that're 1024 points wide and 1024 points long. each point in the grid can have an arbitrary height value, thus giving us a sort of mesh blanket that forms the terrain

"but wait, if each point of terrain can only have one height value, how do caves and stuff exist??" what an astute question, hypothetical reader! and it brings us to the last major renderable object in WoW, the "world map object", or WMO. WMOs are how caves, buildings, and entire cities are stored
