<DIV></DIV>Lots of information missing here.<BR>1) What are you animating?
Single Isovalue for multiple timesteps? Multiple isovalues? <BR>2)
What data type are you using? Native VTK, Native Ensight, or a 3rd
party. Each of the first two give a somewhat unfair advantage to one
product, if you're going for a truly even comparison. <BR>3) What data
format are you using? Structured, unstructured? 2d, 3d?<BR>4) What
pipeline/viz tools are you using? <BR>5) What exactly are you counting time
for? Data load, or just computation? I bet you're just timing the
actual time to generate all the isosurfaces, and Ensight gets a big win
because it preloads all the data at once where Paraview loads it as it goes.
