manihot-lignum

manihot-lignum is a version of the LIGNUM model (Perttunen et al., 1996) specifically for modelling Manihot esculenta (cassava) structure and function. 🌱

Prerequisites

Qt 4.5

Usage

Lignum Workbench

First compile the Lignum Workbench app LignumWb.app for easy visualisation of your tree.

$ cd qt-workbench
$ qmake qt-opengl.pro
$ make
$ open LignumWb.app

Further information can be found under help in the Lignum Workbench toolbar.

Compile model

Change directory and compile the Manihot lignum model.

$ cd ../manihot-sf
$ qmake Manihot.pro
$ make

Run ./manihot with the arguments below to specify model and resulting xml file of tree architecture.

$ ./manihot -iter [number of iterations] -r [random number generator] -load [load number] -model [model number] -x [x coordinate] -y [y coordinate] -L [l-system] -xml [output xml file]

Options

• -iter: Number of L-system iterations. I.e. branching.
• -r: Randomise branching for a more "natural" look.
• -load: Optional. Additional weight from snow/ice etc.
• -model: Type of model to use.
• -x: x coordinate.
• -y: y coordinate.
• -L: Specify L system (e.g. maniot.L)
• -xml: Name of output xml file.

You can then add tree to the Lignum Workbench to visualise your tree! 🌳 🌲 🌳

run make distclean to remove previous compilations.
