Hi all,

        I have an application that draws large areas of adaptive terrain, and I'm
interested in optimizing the drawing speed. We are currently using
triangle strips to represent the terrain, I would like to know is there an
optimum number of triangles per tristrip that would the best drawing
performance. Do non-indexed tristrips draw faster than indexed? Also is
there a similar optimum for the number of tristrip primitives per geoset?
        I typically develop on an Octane with EMXI graphics, and run on an Onyx
with multiple IR boards... I don't know if these numbers vary with
chipsets... Thanks in advance for your help...

Sincerely,

Robert Stein
