3D Computation Dialog

The 3D Computation Dialog box is used to start 3D computation. The dialog consists of five areas: Image information, Computation parameter, Frame Range option buttons, Command buttons, and Message Bar. This dialog box must be closed before you can access any other window.

Image Info

This area contains a list of computation-related information relating to each image used in a Photo4D project. Each line in the list contains the following fields:

1. Image: lists the image name.
2. Selected: clicking on a line toggles this field between:
   • Yes: the image is selected to be used in the computation.
   • No: the image will not be involved in 3D computation.
3. Points: the number of points in the image.
4. Error: the 3D computation error related to this image.

Computation Parameter

Users can set Computation Parameters to direct the 3D computation algorithm for the desired result.

(See Tips for Setting Initial Camera Parameters.)

Frame Range

• Current option button: selects the current frame only for computation
• From/To option button: selects a range of frames for computation. With this option selected, the From and To fields become enabled.

Command Buttons

• Compute: starts the computation process.
• Abort: interrupts the computation process.
• Close: closes this dialog box.
• Help: invokes the on-line reference.
