Interaction

主視圖

以下是在OpticalRevEngDental軟體中選定網格圖的3D互動實例.

以下方式均可與3D視圖互動:滑鼠與鍵盤,上下選單,視圖選單及視圖工具列.

滑鼠互動

用戶可通過滑鼠或由上下選單,視圖選單和視圖工具列中的具體工具選項改變3D物件的方位.

以下提供滑鼠/鍵盤組合鍵表列:

• + 或 + : 顯示2D鏡頭
• : 自由旋轉3D物件鏡頭
• + : 旋轉3D視圖的Y軸
• + : 旋轉3D視圖的X軸
• + : 旋轉3D視圖的Z軸
• : 縮放
•  : 進入上下選單
• + : 改變3D視圖中的光源位置
•  : 使用目前工具 (例如:矩形選擇,填洞等.)
• +  : 如果可用,反轉當前工具 (例如: 取消點選代替點選等)
• + 數字鍵 1 到 7 : 改變3D視圖的默認視角(如:前視,後視,頂視等.)

In the software options, it's possible to enable an "Alternative Interaction" mode which allows to swap the middle mouse button and the right mouse button, in order to set an interaction more similar to other CAD software.

Context Menu and View Menu

The view menu and the 3D View context menu contain some tools that can be used to interact with the 3D View.

• Frame All ( + A) : the 3D camera will move to show, on the screen, all the current selected 3D Objects
• Rotation On View : if this option is enabled, the rotation will ignore the current selected 3D Objects; if it is disabled, the center of the rotation will be the baricenter of the selected 3D Objects
• Area Frame Tool: this tool allows to draw with a rectangle. The rectangle will become the new camera view.
• Center View ( + P)  : the currently selected 3D Objects are moved at the center of the screen without changing their Zoom
• Standard Poses : sub-menu to apply default 3D views:
  • Front ( + 1)
  • Back ( + 2)
  • Top ( + 3)
  • Bottom ( + 4)
  • Left ( + 5)
  • Right ( + 6)

The context menu contains other tools described in the Data Editing page.

Data Information Window

In the view menu, it is possible to enable the Data Information Window with the View Data Window ( + + I) action.

This window provides some information about the current selected 3D Objects.

• Description: a line that describes the type of the currently selected objects (E.g. Triangle Mesh: 2, Range Images: 6, etc.)
• Points: the number of points of the currently selected objects
• Faces: the number of faces, available only for triangle meshes
• Selected: the number of selected points/faces of the currently selected objects
• Size and Position: the minimum/maximum coordinates of the volume of the currently selected objects, and their size in every direction
