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