I am making an open world game. I split the world into segments, 9 of which are always loaded, the player in the center. Move over a segment and I load the next apropriate segments before the player reaches them.
I wanted to do this loading on a seperate thread, but with LWJGL if I load a texture from another thread it cannot be displayed. (I don't have the error but can recreate for it. I found this was the problem from an IRC log google gave me
Each segment may have different textures, and may share some with other segments. Too many texture exist in total to have every single one loaded onto one atlas. If I load everything in the same thread as the rendering is done, there would be a significant pause when you reach the end of a segment. Does anyone have any experience with open worlds and streaming in world data they can share? Specifically though this thread business is my problem.
