Section 5: Blending 3D Data

  • 3D blends are created the same way as 2D blends, via the right click context menu.
  • Currently three 3D blend tools available:
    1. icon5a Cross Section (good for cross-section data visualisation combined with plan-view datasets)
    2. icon5b Single 3D Voxset (good for visualising 3D volumetric data)
    3. icon5c Dual 3D Voxset (good for comparing two 3D volumetric dataset)

Steps

  1. Right click on the blend list and choose the Start new blend … option from the context menu.
  2. Name the new blend to something unique and select the Single 3D Volume blend tool type. Click on the Ok button.
  3. Drag a 3D dataset from the dataset list onto the icon5d blend node. This will link the dataset to the blend tool. Note that 3D datasets must be dragged from Windows Explorer directly, in order to be loaded into the IEP Data list.
  4. Right click on the blend tool to access the blender options via the context menu. Choose an appropriate option for the data field and the voxel mode to be displayed. Note that the burden on the graphic card rendering increases from Point mode to Wireframe mode.
  5. Now choose a Blending mode through the context menu. Manipulate the blender controls to control the visualisation.
  6. Experiment with the other Blending modes, and/or with the Dual 3D blender. Note that a 3D view can be rotated via the arrow keys, and zoomed in/out with the mouse wheel.
Figure 4: The single 3D data blender in slice book mode, for visualising the change within 3D data at a three fixed points of reference. (a) Two different blending results are shown with the orange and purple coloured dot symbols in the blender tool, specifying the position of data in the X direction. Note that the slice separation distance is fixed for both examples. (b) The result of the orange dot that determines the position of the data shown on the three slices. (c) The result of the purple dot that determines the position of the data shown on the three slices.
