PLoS supp. material by Hermann Cuntz
Exports a tree intree as a set of cylinders in the .x3d html format.
A viewer is necessary to use these files.
and BS Contact
can for example load .x3d files.
As opposed to POV-Ray
these programs can only deal with polygons.
As such, the output trees are sets of polygons.
Object is offset by XYZ 3-tupel DD and
coloured with RGB 3-tupel color
(or Nx1 vector, attributing one value per node).
ipart, a set of indices into intree,
allows to use only a subset of nodes,
for example only a sub-tree.
If a viewer is installed and TREES runs on windows
Matlab can call the viewer directly with the option '->'.
>> x3d_tree (sample_tree, , [1 0 0], , , '-o ->')
← RGB (1,0,0) tupel means RED
← '-o' option adds spheres at node locations
