Information (3Dinfo)

Description

3Dinfo displays information on the 3D model and it also allows the edition of the display parameters such the color or the opacity of the objects.

The hierarchy of the objects in the scene is built when the file is loaded.

This hierarchy can be explored in the tree view, tab .

Tree

The treeview contains three mains sections: the hierarchy, the options and the information.

• Hierarchy
  Describe the logical structure of the model. Each item belongs to the structure and it cannot be modified.
   
• Options
   
  • Highlight

    The highlighting allows exploring the model structure from the treeview.

    When this option is checked, each object is highlighted when its name is selected in the treeview.

    The object whose name is selected in the treeview is highlighted in the 3D display.

    This option can be checked directly from the toolbar button

    This button is also very useful when all the original display options of the objects should be restored; when the highlight function is unchecked, the initial display options are restored.

    • Hide
      Hide the unselected objects.
       
    • X Rays
      The unselected objects are displayed with transparency ; this mode is a little bit time consuming and it should not be used with very wide objects ...
       
    • Outline
      The unselected objects are displayed with their outlines.
       
    • Move on
      Move the camera near the selected object.
       
    • Rotation center
      Move the center of rotation into the center of the selected object.
       
    • Invert the selection
      Highlight all the objects but the one with the name selected in the treeview.
       
  • Picking
    While the highlighting allows exploration from the hierarchy, picking allows exploration directly from the 3D scene.
     
    • Highlight
      When an object is clicked in the scene, it is highlighted as if its name has been selected into the treeview.
       
    • Show in treeview
      When an object is clicked in the 3D scene, the treeview is opened and its name is selected.
       
    • Display tip
      When the mouse is stopped on an object in the 3D scene, its name is displayed in a tip window.
       
    • Display tip hierarchy
      When the mouse is stopped on an object in the 3D scene, its name and the whole hierarchy is displayed in a tip window.
       
  • Animate
    When this option is checked, all the changes in the scene are performed in an animated way. The animations parameters are available in the toolbox described bellow.
     
  • Hierarchy
    Display some information on the file and on the model.
     
    • Display
      Allow to choose the items to include in the hierarchy.
      • Entity
        Include the entities that built the objects. The entities contain the geometrics data. Each object could have zero, one or more entities. The entities can be handled only from their owner object.
         
      • Options
        Open a toolbox for each object. This box allows to change the display option, as described bellow.
         
      • Materials
        Include the materials used by the object, if any. Materials allow sharing graphics options among several objects.
         
    • Sort
      Allow to change the sort order of the object list in the tree view.
      • By name
        The objects are sorted by their name in the tree.
         
      • By size
        The objects are sorted by their size in the tree. The size of an object includes the size of the sub-objects.
         
      • By color
        The objects are sorted by their color in the tree.
         
• Information
  Display some information on the model in memory and in the file.
   
  • Model
    Display the information on the model in memory.
     
  • File
    Display the information on the model in the file.

Toolbox

This section describes the toolboxes linked to the items in the treeview.

• Hierarchy

  The toolbox associated to the hierarchy item allows searching an object.

  The text to search in the name of the objects or in their text attributes is entered in the edit area.

  The button launches the search. The result is displayed as an additional hierarchy in the treeview.

  • Object
    This toolbox is associated to each object in the treeview hierarchy. Some display parameters of the objects could be changed using it.
     
    • Default
      When this option is checked, the display options of the associated object come from its hierarchy. As soon as one of the parameter is changed, this option is unchecked by the application.
      The inherited options are grayed.
       
    • Visible
      Allow hiding an object and its children. It is also possible to hide an object directly by unchecking its name in the treeview.
       
    • Two sided
      The object is displayed on its both sides.
       
    • Textured
      When checked, the texture of the object is displayed, if it has a texture.
       
    • Lighted
      When checked, the object is lighted. If it is unchecked, the object receives only the ambient light.
       
    • Mode
      Rendering mode as wireframe, outline, solid or solid outlined.
       
    • Outline color
      Specify the color of the line.
       
    • Solid color
      Specify the solid color. If the object has a texture, this color will be used only if the object is displayed untextured.
       
    • Opacity
      Control the opacity of an object.
       
    • Smooth
      Adjust the smooth angle used in the edge detection.

  • Steps
    Number of steps during an animation.
     
  • Speed
    Duration of the animation.
