<div class=""><br class=""></div><div class="">Beware the movie is about 260 MB.</div><div class=""><br class=""></div><div class="">This is a fairly small simulation but is a good example of what the volume renderer can do. I've implemented an "embarrassingly" parallel script that allocates one datadump/viewpoint to each processor. Here each of the 1717 frames can be partitioned and rendered in about a minute for a 1024^2 image, meaning that on 16 processors this took about 2 hours. If you have questions about how the script works, please let me know. <br clear="all" class="">
