continuous API#

Conversion from discrete to continuous mtg, and vice versa.

In practice, here continuous mtg means the mtg equivalent to rsml.

openalea.rsml.continuous.continuous_to_discrete(g)[source]#

Convert mtg g from continuous to discrete form in-place

Does the reverse of discrete_to_continuous:

openalea.rsml.continuous.discrete_to_continuous(g, position='position')[source]#

Convert the “discrete mtg” g to continuous form in-place

Discrete mtg g is expected to:

have the 3 scales: Plant (1), Axe (2), Segment (3)
have a position defined for all segmeent vertices The argument position defines how to retrieve its value:
- it can be the name of the mtg property the position is stored in
- or a function(g,vid) that returns the position of vertex vid
An axe components is one sequence of successors (edge_type=’<’)

The given mtg is then converted to continuous form:

the vertices at higher scale (i.e. the segments) are removed and their position are added in a list which is stored in the ‘geometry’ property of their complex.
branch axes which are connected to their parent at the segment scale (ie. the 1st segment has its parent on the parent axe) will have their ‘parent_node’ property set to the index of the respective node in the parent geometry. The position of the parent node is added at the beginning of the branch

openalea.rsml.continuous.toporder(g, scale)[source]#: Return the list of g vertices at scale scale in topological order
