I am using OpenGL to render the following scene, using vertex data from one of the map files of a popular MMORPG. The data is chunked and the pictured scene is made up of 256 (16x16) chunks.
However between the chunks I am seeing what I believe to be glitches due to the float precision. Yet I am not doing any large translations and rendering very close to the origin, should I be seeing this problem? The glitches very noticeable as you fly over the scene with it flickering different points along the chunk edges.
I was wondering if I was overlooking something simple or there are tricks other games use to mask this problem. I guess the source data could be the reason for this problem but I am not aware of it happening in the original game.
