Hi Ben I haven't really figured it out yet. The research papers say that one should combine a fixed value which sticks to the geometry with a temporal value which asks what where the values of the closest points one frame before. The first value is easily set on the geometry with a map or a turbulence for example. For the second one you need the value at previous frame node, which only works in a simulated ice tree. My thinking was that in the modeling region you read in all the geodata you need. In the simulation region you read the camera and calculate the silhouette point data. And in the post simulate region you connect the points and create the strands. But reading neighboring points from the previous frame will slow down the process even more. Additional to that I think that at any point in time you would have to work with all the geo points and not just the calculated outline points. How is your research going? What do you think? I won't be able to work on my project in the next two weeks, but after that I hope that I one day get a beta version out :-)
