This example demonstrates the use of density isosurfaces and simple animation.
60000 points from a Gadget-2 galaxy interaction simulation are smoothed
onto a 603-cell cubic mesh using the triangular-shaped cloud
smoothing algorithm. The counts in each cell, nijk, are
scaled by log10(1+nijk), and then
normalized to lie in the range 0-100. The density levels shown are 25% (red)
and 65% (yellow). 3000 points from the simulation are plotted.
Press the [spacebar] to step through the five frames,
revealing the evolution of the merger.
