terrain question

Blitz3D Forums/Blitz3D Beginners Area/terrain question

if i could take a 1024x1024 .b3d terrain mesh, break it up into 128x128 chunks and load them up into blitz3d, what in your opinion would be the best way to handle them? i'm not very familiar with LOD management. i figure the current patch the player is standing on plus any adjacent patch could be shown and all other patches could be hidden/not drawn.

if that would work, would it still not make sense to load up as many patches as I wanted? if terrain patches are loaded up and then hidden are they actually drawn until shown or not? seems too easy.
