danielsusername replied to Marc Syp's discussion List Item Replace -- New Behaviour??

"It just seems a strange behaviour, since only the specified items from the index list are replaced - it would be more logical if no indecies are specified, the list remains unaltered, rather than empty; see images for examples. (first is normal,…"

danielsusername replied to Marc Syp's discussion List Item Replace -- New Behaviour??

"I'm getting similar strange behaviour. When no item indicies are supplied, the return list is empty. I would assume the logic to be: if no item indicies are supplied, the list remains unaffected. "

Benjamin Golder replied to danielsusername's discussion Using the CGAL algorithm library in GH - converting c++ to c#?

"No longer maintained and not really functioning, however. Also, it might not build correctly for access through IronPython (considering that the bindings are written for CPython)"

danielsusername replied to danielsusername's discussion Using the CGAL algorithm library in GH - converting c++ to c#?

"Thanks David. It looks like you are right in that functions of the CGAL library have deeply nested references etc to lower-level frameworks. Was wondering if you/anyone has come across a GH-implementable straight-skeleton code/definition? Looking…"

David Rutten replied to danielsusername's discussion Using the CGAL algorithm library in GH - converting c++ to c#?

"It is possible to invoke methods in a C++ dll using C#. However this requires that all method calls only use very simple data types (booleans, integers, doubles, pointers or arrays of the above, not an exhaustive list). This is how RhinoCommon talks…"

Using the CGAL algorithm library in GH - converting c++ to c#?

HiI have just come across the CGAL (Computational Geometry Algorithms Library) which houses a C++ library of algorithms and data structures for things like delaunay triangulations, search structures, interpolation etc etc.For info, the website is here: http://www.cgal.org/Some of its functionality of course is present in GH but there are some potentially powerful operations that could help in grasshopper definitions.(the one I am particularly…See More

Retrieve Tree Branch returns new tree structure...

Is there any way to retrieve specific branches without altering the branch structure?eg, in example below, shouldn't the return be a tree structure with {0;1} {0;9} {0;13}?the usefulness of this is to keep track of specific sets of data/geometry within specific branches and then be able to access them when needed (ie, feels more like a database...)…See More

"Each new version of GH introduces few components and there is usually no time to discover them all. This one (pipeline) is outstanding, I see how it works for the first time ! Thanks !"
