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.

RoCoCau is embeded into the vitis environment.

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

or :

      gaspcp Scene

with

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