Wish: blend radius according to velocity

The data exposed in RealFlow’s BIN particle files is:
[]Position[/]
[]Velocity[/]
[]Force[/]
[]Vorticity[/]
[]Normal[/]
[]NeighborCount[/]
[]TextureCoord[/]
[]RealflowInfoBits[/]
[]Age[/]
[]IsolationTime[/]
[]Viscosity[/]
[]Density[/]
[]Pressure[/]
[]Mass[/]
[]Temperature[/]
[]ID[/]

Using a Krakatoa Channel Modifier (KCM) on a PRT Loader loading your BIN files you can access any of these channels to make your own Radius channel for Frost. If you aren’t familiar with KCMs, here is an introductory tutorial: thinkboxsoftware.com/krak-in … magmaflow/

Simply make the output node in your KCM write to a channel named “Radius” and tell Frost to “Use Radius Channel” and you should be good to go.

Here: http://www.realflowforum.com/view_topic.php?pid=31724 is an example of a KCM using the RealFlow Vorticity channel to color particles. You should be able to adapt it to set their Radius value instead.

The definitive source for documentation on RealFlow file formats is C:\Program Files\Next Limit\RealFlow 5\doc\file_formats.

When accessing these channels in Krakatoa, use the exact spelling from the list. In general we name exposed particle channels LikeThis, but that is merely convention. Your custom channels can be almost anything. At some point it may enforce valid PRT file channel naming which is described here: http://www.thinkboxsoftware.com/krak-particle-channels/
