VISUS New Features and Fixes
|
|
|
This release is made on February 17, 2004 |
|
|
|
SEGY Amplitude Scaling Controls: Amplitude scaling for
SEGY displays is now easier. From the SEGY Property Dialog, you
can now use the -< or >+ buttons to increase or decrease the
trace scaling. You can also manually type in an amplitude
scale. |
|
|
|
Vertical Slices Measured in Depth/Time: All controls for
selecting vertical slices in 3D SEGY and Grid Model volumes now
read in depth or time instead of slice number. |
|
|
|
File Read/Write Errors: All file permission errors for
reading or writing files will now be flagged with a diagnostic
message indicating appropriate corrective action. |
|
|
|
User Set Program Defaults: The user can now set the
default directory for loading and saving files. This new
setting can be found on the Viewer tap of the Configuration
dialog. Default color maps for Seismic, Surface and Well Log
displays can be set under the Default Color Map tab of the same
dialog. |
|
|
|
Data Conversion Utilities: Four new data conversion
utilities have been added. All can be found under the
Conversion command and are described below. |
|
|
|
|
Conversion of 3D grid models between ASCII and binary formats.
VISUS and the latest release of VECON use the binary formatted
grid models. Older versions of VECON used the ASCII grid model
format and need to be converted to binary before loading into
VISUS. Binary grid models can be converted to ASCII if needed
for other 3rd party programs. |
|
|
|
Conversion of generic ASCII well directional information into a
VISUS formatted well file. The input and output data are
assumed to be in depth. You will need to know the column
numbers of the coordinates and the number of headers to skip in
the input file. User supplied Reference Depth and Datum
elevations will be used to shift the data. Depth well files
have file extension .3welZ. |
|
|
|
Conversion of depth well files to time well files. A file
containing depth/time information is required in addition to the
depth well file for this conversion. Time well files have file
extension .3welT. |
|
|
|
Conversion of 3D SEGY files to 3D Grid Model Format. The Grid
Model file will have file extension .3mdlb. No parameters are
required for the conversion. |
|
|
|
New File Format Support for Shots and Receivers: Two new
formats are available for loading source and receiver geometry
from ASCII files. The new source files will have file extension
.shtZ or .shtT and should contain the X, Y and either Depth or
Time of the sources. The new receiver files will have file
extension .rcvZ or .rcvT and should contain the X, Y and either
Depth or Time of the receivers. Any header records present will
automatically be skipped. Header records are indicated by an *
in column one. These files are loaded with the standard Open
Files command. |
|
|
|
2D Seismic Display Options: Several new features have
been added to the 2D Seismic Property Dialog. The user can now
select a trace range to display, vertically shift the section,
and add transparency. A problem of sometimes missing the last
two traces has been fixed. |
|
|
|
Snapshot File Format: Save Snapshot Image File has added
.gif format to the list of supported formats. The .gif files
will usually be smaller than most of the other graphic file
formats. The original .jpeg, .bmp, .png, and .tiff formats are
still available. |
|
|
|
Salt Proximity Data: Salt Proximity Survey points can be
loaded for display with the File/Import Salt Point Map command.
This uses a generic ASCII loader like the one for loading
Interface Maps from previous versions. |
|
|
|
LAS Log Curve Data: The format restrictions for LAS log
curve format have been updated. The LAS file header must now
contain the STRT, STOP, STEP, NULL and ~A records. All other
header information will be ignored if present. Also corrected a
problem when the curve values do not start at depth zero. |
|
|
|
Orientation Marker: The user can now add an orientation
marker to the VISUS scene. This marker is placed in the upper,
southwest corner of the scene and uses arrows to indicate north,
east and down. To turn on the symbol, use the View/Orientation
command. A Property Dialog is available to change the colors
and line widths for the marker. |
|
|
|
Corridor Stack: The wiggle traces are now color coded by
amplitude. Previous versions repeated the first Corridor Stack
trace eight times in the display. The new version will display
all traces in the file. |
|
|
|
Reset Button for 3D Seismic and Grid Displays: The
property dialog for 3D Seismic and 3D Grid Model Displays now
has a Reset button to restore all display parameters to their
default values. |
|
|
|
New Naming for Arbitrary Cross-Sections: When generating
arbitrary cross-sections through 3D seismic or grid volumes, the
new cross-sections will no longer have the same name in the
Display List as the original 3D volume. The cross-sections will
have _2D_nn appended to the file type with nn
being the sequential number of the cross-section for that 3D
volume. |
|
|
|
Setting the Browser for On-Line Help: By default the
on-line help files are viewed with the JavaTM text window. To use
another browser to view these files, edit the VISUS.bat file and
add the following to the JavaTM command line: browserPath = ＾path￣
where ＾path￣ is the folder containing the browser you want to
use. |
|
|
|
Various Bug Fixes: In addition to the many new features,
various minor bugs have also been corrected. |
