The Volume Builder tool associates 2DObjects (polygons) together based on if they overlap from section to section, thereby creating 3DObjects. The required input is an image file (or window) and a corresponding polygon file. Once the program has made its attempt at associating the 2DObject into 3DObjects, the object numbers assigned to each polygon will be shown inside the polygon. The first number is the object, the second number is the polygon number. You can make corrections using the Change and Rename functions. When all associations are correct, you can save various kinds of information about the 3DObjects.
For notes on how to approach the Modeling process, see 3D Modeling Strategies.

This menu lets you save and load object association files.
Load Object List - Lets you to restore 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 - allows you to save the current object association list to a file.
This menu provides functions that analyze the current object list and save the results as text files.
2D - includes for each 2DObject in a section number of pixels, integrated intensity, area, center of gravity, and center of mass.
3D - includes for each 3DObject, number of pixels, integrated intensity, volume, center of gravity, center of mass.
This menu lets you write out model information for visualization in 3D Model and other packages.
Wire Frame - will create a wire mesh around each 3D object.
Solid - makes a solid representation of the object. Wire Frame and Solid can be converted to each other within the model program.
String of Points - saves the real space coordinates of the surface of each 3DObject in the form of a regular model file. ie- a single string of points connecting polygons within one object together by connecting the last point of each sections polygon to the first point of the next.
String No Cross- draws all the polygons of one object in a single color but does not connect the tail point of one polygon to the first point in the polygon of the next section.
View Model - shortcut to starting 3D Model with the most-recently saved model file.
This can be either an image file or a window. If a window is loaded, you will be able to check to see if the association made was correct. You must first enter the input file before anything else.
The polygon data must be created using Edit Polygons or 2DObject Finder before running this program. The polygon data may be loaded from a disk file by clicking on the Polygon Data button or may exist associated with a window. Once the polygon file is specified, the Create Objects button is active.
This is the range of the sections that will be considered when creating objects. If there are no polygons in some of the sections in this range, the program will attempt to figure out the correct range and prompt for acceptance of the new range before building the object and taking measurements.
Objects can be measured for multiple time points, but if you want to check if the association is being made correctly you must work with one time point at a time.
Objects can be measured for multiple wavelength data, but if you want to check if the association is being made correctly you must work with one wavelength at a time.
When looking for associations, the Volume Builder will not jump over more than the number specified here to find another polygon.
This function does the associating of the 2D Objects into 3D Objects.
When editing the associations, use these fields to specify the current object.
If this toggle button is On, the object specified as "current" will be shown highlighted in the image window.
If Create Objects made a mistake and assigned the wrong polygon to an object, you can use Correct to make changes. Specify the Current Object as object number to fix, then choose the Correct button. A listing of the sections containing the object along with the polygon number from that section that was counted in the object is shown in a menu 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 at the bottom, entering section number then polygon number. Note that only one polygon per section can be included in a single 3D Object.
If more than one polygon from one section belong to the same object, use Rename and give the object containing the second set of polygons the same number as the first.
Removes the current object.
