====== How do I build a plant in Xplo ? ======

On this page, you will build a Rose with the plant editor module.

{{:soft:xplo:private:rosescheme.jpg?200|}}
===== Create a Plant editor project =====

Create a new project and select Xplo's plant editor : 

  * Project > New > <Editor> > Ok
  * Select New Plant > Ok


===== Create the plant element types =====

Before building your plant, you need to set up the types you want to manage in your plant.

{{:soft:xplo:private:rosetype.jpg?200|}}

You can use default types by selecting a type in the "Known types" list and pressing "+" button to move it to the "Used type" column.
Or you can create your own type by clicking "New". In the new windows, you need to enter a type name and a decomposition scale (for instance: scale 2 for axis, scale 3 for growth units and scale 4 for internodes).

For a Rose, define types (Individual, Axis, Internodes, Leaves, Flower) and Scales (1,2,3,4,3)


===== Build the plant architecture =====

In the Browser View, you can right-click on the "Individual" topological node (i.e the plant node) to display a contextual menu. On this menu, you can add a successor, a predecessor, a component or a new branch beared by the selected node.

  * For the Rose, decompose Individual in an Axis (the main stem), then decompose the axis in one internode, then branch a leaf on this internode.

You can use the Copy/Paste function with the contextual menu or with the shorcuts Ctrl+C Ctrl+V. 

  * For the Rose, click on internode > copy > select the axis > paste.

Unordered List ItemThe 3D view displays a default 3D skeleton reconstruction of your plant, that you can [[https://amapstudio.cirad.fr/doku.php?id=soft:xplo:private:howtoloadmtgfilesinxplo&#edit_the_rendering_of_the_plant|edit in the Render editor panel]].

  * For the Axis type the shape <AMAPstudio dir>/data/smb/nentn125.smb.
  * For the Leaf type, set the shape <AMAPstudio dir>/data/smb/feuil126.smb

You need to create attributes to set lengths, diameters, angles.
  * In the browser view, right-click on the column header > Add new attribute
  * In the new windows, set Attribute type = Geometrical attribute > select Length > Apply
  * Repeat for Width, Euler Angle (X) = Phyllotaxy, Insertion Angle (Y), Vertical deviation angle.
  * Close the windows

You can now edit the attributes by clicking in the cells of the Browser View.
  * Edit first internode : Length 4, Width 1 
  * Edit second interNode : Length 6,  XEuler 170° 
  * Edit leaf 1 : Length 10 Width 6 
  * Edit leaf 2 : Length 12 Width 7

{{:soft:xplo:private:rosestep4.jpg?200|}}


  * On the 1st internode, branch a new axis and decompose it in one internode that bear a leaf.
{{:soft:xplo:private:rosestep5.jpg?200|}}

  * Edit new axis (A2) attributes : Length=45, Width=0.6, the internode component : EulerX=135, Orthotropy=10, the leaf : YInsertionAngle=60 Length=16 Width=10

{{:soft:xplo:private:rosestep6.jpg?200|}}

  * Copy/ Paste (x10) the internode of A2 on A2

{{:soft:xplo:private:rosestep7.jpg?200|}}

  * Last internode of the A2 is ramificated into an flower with attributes YInsertionAngle=0 Length=40 Width=5

{{:soft:xplo:private:rosestep8.jpg?200|}}

  * Copy /Paste A2 on the 2nd internode of A1.
