IMapple: a source-sink developmental model for 'Golden Delicious' apple trees

M. Fi¿er, J. Ravi, B. Benes, B. Shi, P. Hirst
Functional structural botanical tree models are one of the most difficult models in biology. We introduce IMapple, a model for 'Golden Delicious' apple (Malus × domestica) trees based on source-sink descriptions of plant resources. Our model uses precise geometrical representations with high quality polygonal meshes and geometric details. We introduce a novel simulation algorithm that provides detailed information about leaf irradiance by simulating direct illumination and self-shadowing. This provides information about incoming light and energy that is distributed by a source-sink mathematical model. Our model aims to be parametric, highly interactive, and usable. Information about the qualitative and quantitative relationships of different parts of the model is provided interactively via a simple graphical user interface or directly from measured data. The simulation runs in 3D, at interactive framerates, and allows for fast experimentation and visual evaluation.
