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 :-)
Greetings
Jakob

Hi there!
As I announced 6 weeks ago on the list, I now finished an alpha version of
my Silhouette Edge Drawing Tool
It still has performance issues when using higher poly objects. Also the
matter of temporal consistency is not yet implemented.

Hope it works for you :-)
Thanks
Jakob

Hi Jakob,
great work ! I am doing some research on silhouettes too but with a
map-driven approach. I am curious as to how you could have temporal
consistency with Ice. Any idea at the moment ?
