End of semester

Finally, I think the semester is over - at least for most of you. (There are a few of you who are continuing on the vertical cities competition.)

Just want to say thanks for all the hard work that you have all put in. It has been a very productive semester, and the work that has been produced is great.

See you all in 5th year!

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.

voronoi fracture

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.

phtj_shapely updated

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.

phtj_urban bug fix

Some bugs have been fixed in phtj_urban:

phtj_radiance V1

I have updated the radiance node - here it is. As usual, copy the otl in the otls folder, copy the py2radiance folder into the sitepackages folder, and put the test.hip and base.rad anywhere you like.

The materials in the base.rad file can be seen here:
