Unless your landscape is full of caves and other interior spaces, I would suggest using some other form of data storage. BSP's are very good at interior sections, but outdoor areas (especially huge outdoor areas, like in a flight sim) are definately not an optimal case for bsp trees to handle. They will work, however. IMHO you would be better served using a different strategy.

Hi

I´m currently developing a graphics engine
for a landscape viewer.
Is it a good idea to use a bsp-tree
to store the data or should I better use
another algorithm to detect if a part is inside the frustumn or outside.

thaks in advance
