RoCoCau (for Root, Collar, Caulinear) is the result of the concatenation of AmapSim and DigR. The result is a simulator that is able to grow both root and shoot systems at the same time.

It is a pure structural simulator with a real botanistic accuracy.
Since it is hosted in the same software environment as AmapSim, it inherits every features including output formats and plugin mechanism (Plug-ins).
To create a new species into RoCoCau, you will have to parametrize both aerial and underground parts using AmapSim and DigR environments.
The running syntax of RoCoCau is then :

      gaspcp aerial root age [seed] [-sGeomSimplification] [-STopoSimplification [-deltaDelta]] [-g[step]] [-gl[step]] [-a[step]] [-oOutputFileName] [-cModule [-eModuleData]] [[-fsstep] -foCustomOutputFormat]

with

      aerial : name of the aerial part of the plant (if single name, .cfg file will be used for parameter file location)
      root : name of the root part of the plant (if single name, .cfg file will be used for parameter file location)
      age : age to be computed
      seed : random number initialisation number
      -s : GeomSimplification is the simplification level on geometrical output (from 0 to 4)
      -S : TopoSimplification is the simplification level on topological computing (from 0 to 3)
      -delta : birth date threshold to build simplified classes
      step : output step (only at simulation end by default)
      -o : output to a particular OutputFileName file (without extension), this MUST be a complete path/filename
      -g : output linetree format
      -gl : output opf format
      -a : output mtg format
      -n : output natFX format
      -c : dynamicaly link the module file Module to the simulation kernel
      -e : provide the current Module with ModuleData as private data configuration file
      -swap : change bytes output order (switch between little and big endian
      -fs : custom output step
      -fo : load a custom output format module
      -posx : the x world position of this plant (cm)
      -posy : the y world position of this plant (cm)
      -posz : the z world position of this plant (cm)
      -begin : the absolute beginning time for growth simulation

      gaspcp Scene

with

      Scene : a text file describing a scene which means that each line consists in a single plant simulation command
