1 - Objectives

Xplo born of an AMAP botanist brainstorming (March 2008) :

What kind of tool to help :

Building Editing Viewing Seeking Exporting

Architectural plant data ?

Build :

Enter/Draw multi-scale tree topology.

Set attributes (length, weight… may be geometrical attributes -> refine drawing).

Generics attributes (a picture can illustrate un detail of the structure)

1 - Objectives

Edit (go with build)

Import various formatted structures (MTG, LIG, GTDS, …) Insert, delete and copy structure entities. Add/modify attributes. Modify/Deform geometry with topologic rules. Time line. Geometric rules to visualize the structure

1 - Objectives

View 3D/2D Multi-scale draw (like the structure).

Seek Select, filter, hide Script

Export Save project Export to diverse formats ( MTG, LIG, Images, …)

Scenario ViewScenario View

3 – Functionalities : overview

3 – Functionalities : build & edit

Builder/editor menu : Users select the relation and the typeof the new topological element to add in the structure.

Type editor : Users create/edit the types to use in the structure.

3 – Functionalities : build & edit

Users easily visualize the structure during the edition and can select elements directly in the 3d view.

3 – Functionalities : build & edit

Copy/Paste, Repeat, Undo/Redo commands and keyboard shortcuts allow quick edition of the plant

3 – Functionalities : build & editAttribute editor : Users can add custom attributes : i.e. weight, state, …

Or geometrical attributes : Length, Width, Insertion angles, …

Each attribute is displayed in a new column and geometry is interactively updated.

3 – Functionalities : visualization

Render editor : Users can select the types to hide/display and change many rendering/drawing options.

3 – Functionalities : geometry edition

Geometry editor : Users can interactively move/add/remove spline control points to change shape of elements.

3 – Functionalities : data extraction

Type filter : Users choose the types to select.

Selection view : display/save the current selection.

3 – Functionalities : data extraction

Attribute filter : Users choose an attribute, a test condition and value to filter.

We have refined the last slide selection : the current selection is now topo_Level1 elements with Lenght attribute > 4

3 – Functionalities : data extraction

Users can plot attributes along scenario time

3 – Functionalities : data extraction

3 – Functionalities : script

Python or Groovy scripts are usefull for complex filtering and topology/geometry reconstruction.

GLOUPS is a plant simulator implementation of the process-based model GREENLAB .

O. Taugourdeau

Fir sapling geometry reconstruction + light interception + data extraction

4 - Xplo 1.0

Developed in Java (multi-platform), under LGPL licence.

For the scene level, a similar software is developped in AMAP by F. De Coligny

Xplo and Simeo are available on http://amap-dev.cirad.fr
