If you have processed your triangle data to match the order as expected by strips, then use GL_TRIANGLE_STRIP otherwise use GL_TRIANGLES. this is irrespective of vertex array usage.

You need to seperate your data filling from your drawing calls.

Fill your vertex list first, then afterwards call your draw routines.

I don''t think you can just make one call to DrawArray unless you''ve set things up correctly, which I don''t think you''ve done. Look into glArrayElement() (I think) to actually do the "drawing" part for you. hint: you''ll need to have 256 triangle strips. think of these as being along either y or x. each would have 512(?) vertices, sorta "stitching" two columns together back and forth...

i got it to work, i studied a nice example at www.prima-tech.com and now everything works just fine. Now the terrain engine performs really fast, almost 85fps, previously only at 45 !

Thanks to you all !!!
