Editing Object Properties

The Object Type dialog edits the current object. One can leave this dialog open and change the current object.

Object Name: Enter a name for the object.

Draw: Turns drawing on/off in image windows.

Open/Closed/Scattered radio buttons: Set how points in object are connected. Open and closed contour objects are drawn with lines between the points; closed contours have a line connecting the last point back to the first one; scattered point objects have no connecting lines.

Front Face: Outside/Inside toggles select which side of the contours will be brightly lit after the object is meshed. This feature can also be used to select an area of interest as inside or outside the contours, for some programs.

Symbols: Chooses how symbols are drawn. Open or filled symbols of three shapes may be drawn at each model point. Symbol size is governed by the Size slider. Independent of whether symbols are drawn at each point, if Mark Ends is selected, green and red crosses are drawn over the first and last points of a contour.

Sphere radius for points: If this sphere size is nonzero, then spheres will be drawn in 3-D at every point of the object. These spheres appear in the model view window and appear in cross-section on one or more slices of the image display. The units are pixels in the image file, i.e., unbinned pixels if images are loaded in binned.

Show spheres on-section only: By default, spherical points are drawn in the Zap and XYZ windows on all sections that the spheres intersect. Turn this button on to inhibit this behavior and have them drawn only on the central section where the point is located. This could be useful if you want to have a circle around the point that is a fixed size in image pixels regardless of zoom, but do not want the point to show up off-section.

Line Width: Sets the width for lines drawn on images, but not for lines in 3D.

Time data: If multiple image files are loaded, this toggle button controls whether time information is encoded in contours as they are drawn. If the button is on, then each new contour that is created will be assigned to the currently displayed time, and it will appear only over images at that time. In addition, the Time Index text box in the Contour/Surface/Point window can be used to adjust the time value of a contour. If the button is off, then new contours will not be assigned to the current time but rather will have a time value of 0 and will appear over images at all times.
