Model, Observations & Parameters

In this page, presentations are about Arecaceae's architecture, growth and development observations and modelling.

Each PRINCIPES model's parameters that are used to model 3D palm-tree architecture are introduced, illustrated, and operating procedure to make observations are detailed. Vegetative and reproductive parts of palm-tree are presented into 2 separated présentations.
For each parameter of PRINCIPES model, we detail :

  • Model assumptions
  • Parameters values
  • Observations and measurements to collect
  • Variables to compute.

Observations, measurements and Field Forms to collect data

PRINCIPES model

Carl von Linnaeus named palm-trees “PRINCIPES” (the princes of trees).

  • Thats's why we named architecture's palm-trees model “PRINCIPES”;
  • PRINCIPES is featured (we hope) for every arecaceaes architecture;
  • This presentation explain the bases of PRINCIPES model;
  • Typology, growth and development, features and observations are detailed to construct the model;
  • Scales, topology, branching, succession, explain how we can build a 3D palm-tree representation;
  • Assumptions of the model and main uses are finally shortly presented as introduction to next presentations.
