Hi Larry and Ravi,
. yes I was working on the plugin. And yes.. if you are willing to check
that. I think what needs to be done is to use a profiler here.
But I am not sure why it took 30 mins. There maybe something wrong. A
calculation with 50 random points took 3sec on and with 100 random
points 10sec my laptop. May be it is teh point configuration. But it
could be as well that the polygonizer takes some time to create polygons
from all the edges.
@Ravi:
. what process takes that much time.. (the dialog should say what it does)
. did you choose the new option to include the background?
maybe the only way is to work with your point data.
On the masking: Mask meant, that the output polygon size will be
determined from the background layer. So there is no clipping but an
extension to cover a specific area.
Or is this a functionality improvement proposal?

@Ravi, Thanks for the comments and suggestions for continued improvements.
@Stefan, Are you working on ThiessenPolygons? I could take a look at
it if you want. I don't know the algorithm, but I know some of the
usual bottlenecks in JUMP plugins. One of the most common slow-downs is
caused by updating the layer as the new elements are generated. Turning
off the update until the process is finished can dramatically speed up
some operations.
regards,
Larry Becker

Hi,
The differential buffering based on attributes is good.
Reduces some steps in Mineral prognostication.
CreateThiessenPolygons:
Mask layer ??
does it clip the boundaries of the thiessen polygons..
I dont get the result clipped as per mask !
Still I have to do geometric operation A-B to achieve the same.
CreateThiessenPolygons TIME TAKEN
This takes a lot of time
Ex: 100 points took 30 minutes.
How to speed it up please.
I use the latest nightly build.
Cheers
Ravi Kumar
