The Join SOP in houdini is very useful for joining small lines into polygonss. However, in the last few days we discovered that it does not work well in all cases - depends on how the lines are organised.
So I have added two new operators to the phtj_shapely node for joining lines. The Join 2d op simple joins any lines that it can find whose ends are touching. The Join and Close 2d op will join lines to try and find closed polygons.
I have made an example of using the vornoi fracture node. This might be useful for a number of groups.
There are also a few other things that might be useful to look at. For example, using a scatter, followed by triangulated2d, and then polyreduce, in order to get evenly distributed set of points. (This may also be done using particles).
In order for this to work, please make sure that you install the latest phtj_shapely.
The offset node in phtj_shapley has been updated. It now remembers the edge/surface setting, and an additional resolution parameter has been added. This parameter can also be set to negative numbers - draw a v shaped line and test to see what happens.
