Joachim,
it is for redenring a huge landscape, which is culled by changing the
indexCounts and IndeyArray. now i want to add textures generated on the
heights of lanfscape (indeed some are blenden together depending on ther
heights..). futher on i thought of s.th. like this: genreting 3 generated
textures packages for an LOD and add them to rendered field similar to the
last pic.

( each rectangle will be represented by a single 128x128 texture)
(the viewer stands at the botton)
i tought about this, because textures far from the viewer are scaled down,
so i can use one reprenenting a biger area without a quality loss for the
viewer..
o.k. probably i will use one TexcoordArray with the finest structure (pic 1)
and generate different TextureCoordIndex-Arrays (well, this is the only
thing i am afraid of because i need one for each texture) on them..
finally one big textures would be too huge for landscape, even for the part
actuallay is rendered i guess...
anyway thanks for you answer Joachim :)
if you all have some thoughts about problems implementing that or think
having a better way feel free to comment.
greetings
Michael Nischt
