Résumé
Since the early 90’s, AMAP lab (Montpellier, France) has developed multiple softwareapplied to plant architecture modelling. More recently, AGAP Institute developed the OpenAleaplatform (Pradal et al., 2008) to answer the growing need for computational resourcescoming from the increasing complexity and scale of applications of plant models, and fordata analysis associated to new data acquisition techniques such as high-frequencyphenotyping platforms or LIDAR measurements. Both AMAPstudio and OpenAlea aredesigned for providing modelling tools for the FSPM community, they share commonformalisms for plant representation (i.e., MultiScaleTreeGraph, mtg; Godin et Caraglio,1998) and similar 3D edition and visualization tools. However, these tools have largelydiverged for multiple reasons: language source code, integration in different platforms,plants with different architectures studied for specific research topics but also differentlaboratories with distinct needs and directives. In this context, researchers and engineers specialized in mathematics and computer sciencefrom AMAP and AGAP decided to gather their expertise into the Mathematics & ComputerScience (CS) network For multiscale functional structural modelling of Plants within theiragroecological systems (MaCS4Plants). This network aims at providing an extensive libraryof generic functional models as well as tackling scientific problems in the math and CS domain applied toagroecological transition and resilience to climate change: big data analysis, hybridmodelling, multiscale and structure-function studies or full plant modelling (i.e., root andshoot). In this study, we will present the first achievements of the MaCS4Plants network:- An extensive catalogue of modelling software developed and their integration intoOpenAlea (https://openalea.rtfd.io).- The proposal of a standard format that integrates both topology and geometry atmultiscale of plants, and the possibility to export it toward common 3D visualizationsoftware.- A set of online didactic interactive notebooks on FSPM.
