Thank you very much for taking the time to reply, David And my apologies for the delay in replying
I hadn't picked up on the availability of line segments, they look to be just what I need Concerning the length as the velocity, can this be related to realworld units? Am I correct in saying that each line segment is 'about' 3 frames in length (this would allow me to work out distance over time) Thank you for your help Jeremy On Mar 25, 12:04 am, David Rutten <[email protected]> wrote: > Hi Jeremy, > > the mesh doesn't really link to the particles in an obvious fashion. > > It sounds like if you import the RealFlow data as a group of line > segments, you can then reference them all, use the startpoint as the > particle position and the length as the velocity. > > -- > David Rutten > [email protected] > Robert McNeel & Associates > > On Mar 24, 8:03 pm, JezRick <[email protected]> wrote: > > > > > > > Firstly thank you for the RealFlowImporter, it's been very helpful for > > my current project. > > > When you import RealFlow Particles or Meshes into Rhino it also > > imports the Speed/Velocity data.
