Tortuosity is a measure of the bendiness or curviness of a path. Tree branch motion paths are piecewise linear curves created by collecting position information over time for fixed locations on a tree branch. Objective methods for comparing branch motion paths may improve computer simulations of tree motion for image synthesis by giving researchers another tool for evaluating and improving simulation methods. Three tortuosity metrics are computed and compared for 22 motion paths collected from a maple sapling in a laboratory environment. Appropriate metrics for tortuosity of tree branch motion paths must account for short chord lengths of those paths, admit analysis of space curves and match intuitive notions of bendiness. Tortuosity itself is a subjective measure. We present several images of branch motion paths along with their tortuosity values. Based on these results, average curvature is the most appropriate metric for characterizing tortuosity of tree branch motion paths because average curvature is not sensitive to chord length, is defined in 3D and is well correlated with our intuitive notion of tortuosity.","PeriodicalId":117786,"journal":{"name":"2012 IEEE 4th International Symposium on Plant Growth Modeling, Simulation, Visualization and Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130217635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It contains interactive tools to handle the topology (e.g. organs addition or deletion), the geometry (e.g. 3D selection, edition, rotation) and the dynamics (i.e. time line, scenarios) of plants at the individual or scene scale. AMAPstudio is based on the Multi-scale Tree Graph (MTG) data structure, which is commonly used to represent plant topology. Users can explore this data structure to test or to improve hypotheses on plant development. Specific data can be extracted with combinations of criteria and can be visualized in tables and graphs. Simple analysis functions can be launched or data can be exported to external tools, e.g. R, or any other statistical computing environment, for more specific analyses. AMAPstudio is also a framework in which modellers can integrate their own plant simulation models. Different scenarios can be computed for a growth model by interactively modifying model parameters or plant structure (e.g. by pruning) at particular time steps.","PeriodicalId":117786,"journal":{"name":"2012 IEEE 4th International Symposium on Plant Growth Modeling, Simulation, Visualization and Applications","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126973149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the difficulty of collecting experimental data on adult trees, models can be used as tools to disentangle the complex processes that drive biomass production and allocation. This paper investigates the variations of parameters with age driving the source-sink balance of individual trees through the functional-structural plant model GreenLab. Six Chinese pine (Pinus tabulaeformis Carr.) trees were destructively sampled and were divided into three groups based on ages: 5-year old, 10-year old and 18-year old. Firstly, the effects of age on organ dimensions and on organ relative mass were analyzed based on direct experimental measurement. Secondly, the hidden parameters of the GreenLab model were estimated using the data of total tree biomass for needle and wood compartment independently and then for the six trees in parallel. The statistical tests showed that there were significant differences between the tip attributes on first-, second-, and third-order branches of the three age stages for internode diameter, internode sink and needle sink. Preliminary fitting results showed that the sink of layers and the parameter of biomass production efficiency 1/r decrease with age.","PeriodicalId":117786,"journal":{"name":"2012 IEEE 4th International Symposium on Plant Growth Modeling, Simulation, Visualization and Applications","volume":" 43","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113951707","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
