Density Visualizations of an Isolated Galaxy

Uses the DensityCalculation with the following parameters:

The relatively small alpha scale is what causes this visualization to be so much better than the previous ones at InnerStructureSplattingHistory. It allows the opacity to not be saturated as quickly, which is what leads to a loss of information. Note the apparently very fast spinning center of the cloud and gas movies.

Density Visualizations of Interacting Galaxies

Uses the DensityCalculation with a constant hue (red) with the following parameters:

As per StefanHarfst^?'s request, a constant hue was implemented for these movies to make density a bit more obvious. The result of this is that the alpha scale had to be turned up a bit and some detail was lost in the stars and clouds movies. A future movie set will seek to resolve this.

Comparison of density rendering and point rendering of gas particles

This movie validates my density rendering using the DensityCalculation as being correct with respect to the point rendering. The same features are visible in both renderings, in particular a particle discharge at ~500myr.

New stars created during the interaction betweeen two galaxies

This movie shows all stars that are created (tob>0) during the interacting galaxies simulation. This would appear to show the TidalDwarfGalaxies^?.

Young stars created during the interaction between two galaxies

This movie shows all young (<50myr) stars on the right and all stars on the left during the interacting galaxies simulation. This would appear to show the TidalDwarfGalaxy^?. In particular, one can see a TidalDwarfGalaxy^? enter the left of the frame at ~750myr. New star production seems to cease at ~900myr when it nears the center of the system and seems to flare at ~1025myr after it has been slingshotted around. This pattern of star production after rounding the center of the system can be seen in numerous places and times.
