Hello all,

Does anyone know if the v.trees3D vector add-on (for extruding trees from points) is still accessible? Can’t find it in the current svn so I am assuming not… if this is the case does anyone have any other cool suggestions for auto-modelling 3D trees from point data?

Thanks for reading,
Rebecca

I found the source code of this module at [1] (cc'ed original author
Jachym Cepicky, could be that he is planning to upload his modules to
AddOns SVN :slight_smile:

Thanks for the link Martin.
I did a bit of digging and found these instructions for adding the v.trees3D add-on without using g.extension

http://les-ejk.cz/programs/?cat=gis#### InstallationIf it is an tgz package, it is most probably the C-source code:

  • Copy the file in the GRASS source directory to proper directory (raster
    modules in raster, vector in vector etc.).

  • Untar the archive with tar xzf modulename.tgz

  • Go to the new module directory and run make:
    cd modulename
    make

  • Go to the GRASS source directory and run make install for
    installing it.

Can anyone tell me if these are still valid - I only ask because I don’t see separate directories for raster and vector modules in my install (~usr/lib/Grass64/bin, GRASS version: 6.4.3RC2 on Ubuntu 12.04 precise)?

Yes that still works–it also works for python modules, but you add it to wherever you unpacked your grass source code (such as in ~/source/grass_trunk), not where grass is installed. Did you compile grass or are you using a version from the repos?
