The 3D Modes

 

These modes only display and manipulate 3D objects. When one of these modes is active the 2D and TAG tools will not be available. Any window associated with a TAG Mode will be in 3D mode. The available modes are:

 

Display 3D

This Mode only displays the 3D objects. It has no other functions.

 

Contour Lines

This mode creates 3D contour lines around the TAG pixels in all the selected frames. The line can be composed of line segments or just points. Unlike the Shell modes, this mode does not impose any constraint on the frames it can use.

 

Shell TomoVision / Lorensen

These modes are 2 variations of the same thing: They are used to create a polygonal shell around the TAG voxels. The Lorensen algorithm will produce a a more detailed geometry with a LOT more polygons. If you need to decrease the number of polygons, you should use TomoVision's algorithm. Both algorithms will only be able to create a geometry from the frames of a single parent. And these frames must be aligned, parallel and all have the same image resolution and pixel metrics.

 

 

The mouse controls

 

The mouse is used to rotate, translate and scale the displayed objects. The mouse can be in one of three modes of controls: The Track Ball, the Classic or the Patient modes.  These are explained in more detail in the "Transform" section of The 3D Tools.

 

 

From the Keyboard

 

There are a few keyboard keys that have been mapped to commands that can be used in all the 3D modules

 

 



 

Key

Function

 



 

Print_Screen

Create a snapshot of the display area

 

Also, if the "3D Slices" tool is enabled, then the following keys can be used to manipulate the slices:

 

 



 

Key

Function

 



 

Page UP / Page Down

Change current frame within its parent

 

Home / End

Change the current frame by changing the parent

 

F1 to F4

Select display modes "Grey", "Mixed", "Over" or "TAG"

 

"+" / "-"

Increase / decrease TAG opacity in Display Mode "Mixed".

 

 

From the Command Line

 

A number of commands affect the tags. These can be found in: "SliceO_System\3D.dll" section of Appendix B.
