2D and 3D windows

 

A window is either 2D or 3D depending on the current mode that is associated with it. For example if you select "Edit" from the Mode menu, then the current window will be a 2D window and it will be associated with the Edit Mode.  If you select "Contour Lines" from the Mode menu, then the current window will be a 3D window and it will be associated with the Contour Lines Mode. 

 

Each window has its associated mode. If multiple windows are present in the display area, clicking on one window will make it the current window. The associated mode will automatically be presented in the control area, and the tools that are selected and are compatible with this Mode will be also be displayed.

 

 

2D Windows: Mode All and Mode One

 

The 2D windows can be used to display either all your frames (Mode All) at once or just one frame at a time (Mode One).

 

Mode All

The database tree with all the frames is displayed. If all the frames cannot fit on the screen, you can use the vertical slider to pan through them.

 

The complete tree, anchored at the root node, is shown.. Each branch of the tree that has more than 1 child can be in one of 4 states:

 

Expand

All the children of this branch are displayed.

 

 

 

Single

Only one of the children is shown at a time. The slider can be used to select which child is visible.

 

 

 

Loop

Only one of the children is shown at a time. The children are cycled automatically after a short delay.  The slider can be used to adjust this delay from 1 sec to 1/30 sec.

 

 

 

Collapsed

None of the children are visible

 

 

Branches that have only 1 child can only be in "Expand" or "Collapse" states.

 

The state of a branch is changed by clicking on the symbol at the left hand side of the branch

 

 

The current frame will be highlighted by a yellow border, and all the branches higher in the tree that contains the current frame will have their icons highlighted in yellow.

 

To help distinguish between selected and unselected images, unselected images will be drawn without their red component.

 

 

Mode One

Only the current image is displayed. If it cannot fit on the screen, you can use the horizontal and vertical sliders to pan through the image.

 

Pressing the “Ctrl” key can also be used to drag the image with the mouse.

 

The displayed image is selected either with the Slice Selection Tool, from the keyboard shortcuts, or by clicking on the desired frame in Mode All and switching to Mode One.

 

 

 

In Mode One, only the current frame is selected.  This means that most operations (for example, thresholding the images in the Threshold Mode) will only be done on the current frame.

 

Switching from Mode One to Mode All will also select all frames.  This means that most operations will be done on all the frames.

 

 

3D Windows

 

 

3D windows show objects in 3D space.  By default, all 3D polygonal objects loaded or created in sliceO are visible (you can use the "3D Shading" tool to change their appearance and visibility).  In certain modes ("Contour Lines", "Shell") you will also see the contours of the TAG surfaces from each selected frames.  And if you activate the "3D Slices" tool, you can see the selected frames in 3D space.
