> Hi Yuan. > Loving the trajectories in my class this week! Thank you for the effort to > create that. > > One slight bug: > > When I draw multiple "Close Polygon" areas around vorticity features at the > initial time, then click Create Trajectory, the tracers from the first few > polygons appear one timestep downstream. Only the final polygon's tracers are > displayed at the initial time. See the image below. > > Brian > Hi Brian, Always good to hear my favorite feature being used in the classroom. The initial position of the tracer is a known bug of the ViSAD library. If you change it to point, you will see the right position. Sorry about it.
