4. Simulation Results

You can explore the simulation output by either inspecting the tree plotting in Two Dimension (2D) and Three Dimension (3D) graphic or plotting the tree data on statistical chart.

4.1. Vertical Projection 2D of Tree Plot

You can access the shortcut to view vertical projection from simulation menu (see section Simulation Menu).

4.1.1. Tree Paint Options

You can set the tree painting on the 2D plot by right click the plot, select “paint”.


Figure 71 2D Tree Paint Options Menu

Default option is paint with Outline mode. You can reset either with opaque, transparent, or shading mode.

4.1.2. Tree’s Info

You can view the basic info of the plotted trees by selecting the “Show” menu. You can show either the ID, Species Label, CP index or CF index. see Figure 75.

4.1.3. Overlay Map

The plot can be overlay with either “Light Map” Layer or “Root Influential Zone Map” Layer. To set the overlay map, select “Overlay Map” on simulation menu,

Figure 73.

4.1.4. Cut the Trees

On Vertical Projection Plot you can cut (remove) the trees. Select the trees, Right click, and Select “Remove”. Note that those removed trees are also removed from the simulation and counted as mortality data.

4.1.5. Tree’s Object Inspector

This menu will show the technical properties of Tree Object.

4.2. Horizontal Projection 2D of Tree Plot

To view the trees on horizontal projection, select the tree from Vertical Projection Plot, Right click and select “Horizontal View”. You can view the projection either from North, South, West or East side.

4.3. View 3D Visualization

You can explore the tree in 3D Graphics. Make sure that you have minimum requirement for viewing the 3D graphics (see section Minimum Requirement). You can access the 3D Visualization shortcut from Simulation Menu


Figure 80: 3D View in Simulation Menu


Figure 81: Virtual Forest Setting.

After you select the “3D View” menu, the Virtual Forest Setting dialog will appear ( Figure 81).

The 3D visualization setting options are:

  • Crown type
    You can set the Tree Crown rendering type either using Wireframe, Solid or Leafy modes.
  • Land Type
    You can set also the Land rendering either using Wireframe or Solid modes.
  • Texture
    Texture rendering can be applied for each 3D components: Sky, Land, Crown and Trunk
  • Topography
    Check if you want to enable the topography rendering on 3D Visualization (make sure that you have applied the topography data)
  • Mouse Control
    Check if you want to enable moving the 3D Objects using the mouse.

4.4. View 3D Animation

Select a tree or a group of trees on Vertical Projection View window, Right click, and select show 3D (Figure 85). Make sure you have enabled the “Record Tree Profile History” option on Simulation Plot Setting (Section 3.2)

4.5. 3D Visualization Window Menus

The 3D window shortcut menus are:

4.5.1. Snaphot

Click here to capture the image from 3D Visualization. Set the scaling factor then click Ok. The snapshot window will show up. After, you can either save the image or print it .

4.5.2. Rendering Mode

You can set the rendering mode of the 3D Visualization either using wireframe or solid mode


Figure 88: Tree in Transparent Mode


Figure 89:Tree in Solid Mode

4.5.3. Show 3D Component Part

You set the 3D Visualization to show the part of object. You can set either just showing the crown layer ( ), the branches ( ) or both crown layer and branches ( ).

4.6. Hemispherical Photograph

You can view hemispherical photograph model of canopy gap from a tree point of view. Select a tree on Vertical Projection Plot, Right click, and select “Hemiphot”. The hemiphot window will show up (Figure 92).


Figure 91: Hemiphot Menu in Vertical View Window


Figure 92 Hemiphot Window

There are two type of hemiphot map:

  • Canopy openness
    This represents the canopy openness computed at crown base assuming target tree crown is completely transparent
  • Sectoral Light .
    Sector light is a smoothed map of canopy openness used to compute anisotropic gradient affecting crown deformation

You can try to change the light insolation setting for current hemiphot position by opening the “Setting” tab. click Calculate button to refresh the hemiphot after you change the setting.

You can view the detail value of each hemiphot sector by opening the “Table” tab.


Figure 93: Hemiphot Table

4.7. Statistical Data

Statistical data output can be accessed either for overall simulation list, for selected simulation or for each individual tree. To view overall simulation list statistical data, open the “Statistical Chart” menu on the Main Window menu bar and select the type of the chart.


Figure 94: Statistic Chart Menu for Overall Simulation List

To view the statistical data for each simulation items, select (Highlight) the simulation item on the simulation list window, right click and select “Statistic Chart”.


Figure 95: Data Option in Simulation Options

To view statistical data of individual tree, select a tree on the vertical projection plot, Right click, then select “Tree Statistic” (Figure 104).

4.7.1. Bar chart

Select the variable on the left panel and move it to the x axis panel on the right. The available x axis variables are DBH (Diameter at Breast Height), Height, CP Index, CF Index.

“Species” and “Simulation” are the grouping variables.

You can view the simulation data of any age by setting the Age field.
