Volume rendering of a single time step from a Gadget-2 galaxy interaction simulation.
The simulation comprises 60 000 particles, which are mapped onto a
403-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 S2PLOT ns2cvr()
and ds2dvr() functions were originaly used to create and display the
real-time volume rendered cube, and the latter function has been
re-implemented in Action Script 3 for use on a Web page.
Papervision3D does not provide texture smoothing as this is
computationally expensive in software, hence the pixelated appearance
of the render.
