Math Operation
Choose Math Operation to open a dialog that allows to manipulate the volume field in different ways. Each math operation generates a new volume image containing the modified volume field. The single volume fields can be saved in *.guf format or the complete modified volume file can be saved, after the unwanted volume images were removed.
Available Math Operations
Subtract Field
Choose another loaded volume field, that will be subtracted from the current volume field.
|
Important! The volume fields must be of equal size.
|
|
Add Field
Choose another loaded volume field that will be added to the current one.
|
Important! The volume fields must be of equal size.
|
|
Normalize Field
Define a new minimum and maximum value to normalize the values of the volume field accordingly.
|
Compute Gradient
No further parameters are needed to compute the gradient for the current volume field. This results in a vector image with the three component vector fields and the supplemental field of the norm.
|
Convert to Data Type
Choose a new data type (single, uInt32, uInt16 or uInt8) and convert all values of the current volume field to this type. The current data type is grayed-out and cannot be selected.
The math operation Convert to Data Type with the type uInt8 or uInt16 chosen offers further possibilities in the right-click context menu for the converted volume field.
You can then Open it in the Image Processing Dialog (see the ImportGeo-Vol handbook), Create a Triangulation, Save as 2D Image Stack, or Save as 3D Image.
Use the math operation Convert to Data Type to save a volume field as RAW-file, as explained here.
|
Add / Subtract Constant Value
Add a constant value to the volume field. Enter a negative value to subtract it from the volume field.
|
Multiply Constant Value
Multiply each entry in the volume field by a constant factor.
