VISUS New Features and Fixes
|
|
|
This release is made on September 8, 2004 |
|
|
|
Conversion between 3D grided models and SEGY volumes:
Two new utilities have been added under the Conversion menu.
One option converts 3D grid models to SEGY format and one
converts 3D SEGY volumes to 3D grid models. Except for the
input and output filenames, no parameters are required. |
|
|
|
Export vertical slices in either SEGY or 2D grid model
format: Vertical slices created from SEGY or 3D grid models
can now be saved as either SEGY files or as 2D grid models (.mdl
files). The command to save these files can be found on the
vertical slice property dialog. The saved files can be viewed
in either VISUS or VECON. |
|
|
|
Tool to measure selected area in scene: To measure the
area of an arbitrary polygon inside the VISUS scene, select the
new Measure Angle icon from the main screen. Using the right
mouse button, select points to define the area of interest. To
close the area, select the first point again. The calculated
area will be displayed in the lower left of the window. You can
then measure another area or select the icon again to close the
measurement tool. |
|
|
|
Export sub-volume of a 3D SEGY or grid model: Any
user-selected sub-volume of a 3D SEGY or 3D grid model can be
saved as a new 3D SEGY volume. Using the Scan Sliders on the 3D
Seismic and Grid Model property dialog, select the boundaries of
the new sub-volume. The Subvolume Export button, located on the
same dialog, will create the new file. |
|
|
|
Color-coding for down- and up-going raypaths: For
reflection raypaths, the user can now control the incidence
(down-going) and reflection (up-going) segments of the rays
separately. The incidence and reflection segments now have
their own color selection or can be switched on and off
independently. Reflection points can also be added to the
display. The size and color of the reflection points can be
adjusted. |
|
|
|
Information panel for 3D grid models and SEGY volumes:
The 3D Seismic and Grid Model property dialog now has an
Information tab that displays full information about the model
or volume. |
|
|
|
Generic ASCII grided layer conversion: 3D grid layers
exported from any third party software can now be loaded into
VISUS. The File/Import Grid Interface command is used to
convert the grid to an XYZ file that is loaded with
File/Interface. To convert a 3D grid file you will need to know
the number of grids, grid spacing and origin, and the data order
in the file. |
|
|
|
Added support for Linux: Visus is now available for
Linux computers. Contact us for additional details. |
|
|
|
AGC and other scaling options for 2D and 3D SEGY display:
The 3D Seismic and Grid Model property dialog now has a
Seismic Display tab for selecting the type of scaling to use for
the display. Traces can be scaled individually or with a
constant scalar based on RMS, Max/Min, or Average amplitude.
AGC with user-defined window length is also available. |
