The easy way to compute proper vertex-based normals for indexed sets is to set all the normals to [0, 0, 0], then, for every triangle calculate it’s normal and simply do a vector add of the calculate tri normal to the normal for each vertex associated with the triangle.

This is an image from an elastic wave propagation simulation. Brian Sumner wrote the simulation on an SGI server. I wrote the visualization component. We designed a shared memory transport/communication protocol for the IPC. Here are a few more images
This is a rendering of rainfall from Hurricane Isabel. This is not a time-based rendering; notice that the eye does not move. Rather this is an animation of the visualization of rainfall rates at one particular moment in time.
