3D Object Builder Settings

Use the 3D Object Builder tool to create 3D Objects by associating 2D Polygons that overlap from section to section. The required input is an image file (or window) and a corresponding polygon file. After the program attempts to associate the 2D Polygons into 3DObjects, the object numbers assigned to each polygon are shown inside the polygon. The first number is the object and the second number is the polygon number. You can make corrections using the functions in the Correct window. When all associations are correct, you can save various types of information about the 3D Objects.

Open this window by clicking 3D Object Builder on the 2D Polygon Finder window.

Use	To...
File	Save and load object association files. *Load Object List* restores previously created object associations back into the program so that you don't have to recreate the objects over and over again. *Save Object List saves the current object association list to a file. Quit q*uits the program.
Measurements	Analyze the current object list and save the results as text files. Table of 2D Measurements creates a table that includes the number of pixels, integrated intensity, area, center of gravity, and center of mass for each 2D Polygon in a section. The center of gravity reflects the geometric center of the polygon; the center of mass indicates the center of concentration of intensity. Table of 3D Measurements creates a table that includes the following for each 3D Object: the number of pixels, integrated intensity, volume, center of gravity, and center of mass.
Model	Save model information for visualization in 3D Model and other packages. *Save Solid* *Model* makes a solid representation of the object. *Save String of Points* saves the real space coordinates of the surface of each 3D Object in the form of a regular model file (i.e.- a single string of points that connects polygons within one object together by connecting the last point of each section's polygon to the first point of the next section). *View Model* provides a shortcut for starting a 3D Model with the most-recently saved model file.
Input Image	Input an image file name or a window number. If a window is loaded, you can check to make sure that it has the correct association. You must enter the input file before you enter any other fields.
Polygon Data	Load polygon data. The polygon data must be created using Edit Polygons or 2DObject Finder before running this program. The data can be loaded from a disk file by clicking on the Polygon Data button or it can be associated with a window. Once the polygon file is specified, the Create Objects button is active.
Details	Specify the Z and time point region information.
Wavelengths	Measure Objects for multiple wavelength data. If you want to make sure that the association is made correctly, you must work with one wavelength at a time.
Color Objects By Wave	Assign colors to objects based on the wave to which the objects belong. When deselected, colors are assigned to objects by cycling through the list of available window graphics colors (about 12 colors).
Maximum Z Gap	Specify the maximum Z distance to search for an association. When searching for associations, the 3D Object Builder will not jump a larger distance than the Maximum Z Gap to find another polygon.
Build 3D Objects	Associate the 2D Polygons into 3D Objects.
Correct	Reassign a polygon to an object if the Create Objects tool assigns the wrong polygon. Specify the Current Object as the object number to fix, then choose the Correct button. A list of the sections that contain the object along with the associated polygon is displayed in the Correct Object List dialog box. You can edit the polygon number for that section. If there is no polygon from an included section in the object, change the polygon to zero. If a section was not included that should have been, you can add it by entering the section number followed by the polygon number. Only one polygon per section can be included in a single 3D Object. Current Object, Wave, Time specifies the current object when editing the associations. Delete Current Object removes the current object. Delete From List removes objects from a list.
