Well logging, storing of one or more physical quantities in or around a
well, is used to characterize subsurface stratigraphy in a wellbore.
Once imported, well log curves can be displayed along the well path.
Avizo Fire Edition - Improvements and new features
- Huge Performance enhancements
Most of the image processing commands have been parallelized in order
to optimize the usage of multi-core CPUs. The performance gain is
proportional to the number of cores. For instance for the mediafilter

specify the seed points using a HxVertexSet data object.
- The DisplayLineSet display module now allows you
to specify the complexity for spheres and circles.
- Colormap management improvements:
- Each scalar data set now has a colormap port.
By default it is disabled. When enabled (using the edit popup menu),
each display module attached to this data set will automatically use
this colormap. Assigning a colormap is thus much easier than before.
- Colormaps appear in a specific color in the
pool as soon as they are used by a display module or a data set.
Colormap now are visible when used. They can be easily identified in
the pool by their specific color.
- A new edit button has been added to the
colormap port to replace the old right button click. Editing colormaps
is much more natural this way.

New Avizo XGreen Pack
The new, separately licensed Avizo XGreen Pack, can
be used to visualize weather and climate data
from Simulations with numerical Earth System Models.
With its powerful NetCDF-CF1 file interface, the
Green Pack allows you to read and visualize the
typical long time series of multivariate 3D data produced by weather
and climate models by using
the most commonly used native file formats. Depending on the local
hardware configuration, large
files can be cached in memory in order to accelerate the interactive
access. Very large time dependent
files can be visualized right away from the hard disks.
A topography and map module, complemented by a geographic projection
module with user definable
exaggeration of the vertical axis allows to interactively explore the
data in the correct geographic
context.
Avizo XGreen Pack offers a wide range of state of
the art visualization methods as well as some
advanced methods and features like Line Integral Convolution (LIC),
Illuminated Streamlines (ISL) or
Particle Advection for visualizing vector fields like wind and ocean
currents.
Avizo 5.0 Changes - Improvements and new features
Avizo versus amira
amira grows and evolves. Initially known and widely
used as the 3D visualization tool of choice in the Life Sciences
research market, amira® has become a more and more
sophisticated product, delivering powerful visualization and analysis
capabilities in all visual simulation fields. Application areas such as
Material sciences, Computer Aided Engineering post-processing, Virtual
Reality and more, are becoming active adopters of the product.
To highlight our focus and commitment to these
application areas, Mercury is introducing a new product name: Avizo.
Using the same great core software plus domain specific extensions,
amira® will continue to serve the Life Sciences market, while
Avizo will address all other industries, such as Engineering &
Manufacturing, Non-Destructive Testing, Material Sciences, Geosciences,
Immersive VR and other industrial and scientific domains.
Editions and Packs
For former amira users, the former pack names has
been renamed. For more information, see "About editions and extension
package" chapter which is accessible from a link on the home page of
the Avizo help browser.
Improvements and new features
Avizo
Pool -- Graph View/Tree View, Pool/Explorer
In
previous versions of Avizo, the Pool displayed your data objects and
modules and their connections in what could be called a "graph view".
This feature is, of course, still available. However, it is now
possible to select instead (via Edit/Preferences/Layout) a "tree view"
of your data objects and modules. This can be useful when working with
large numbers of objects as it allows you to organize them into folders.
Note: When in tree view mode, the Pool pane and the
Pool menu are relabeled "Explorer".
Although the look of the tree view is quite
different, the principles are the same. You select an object by
clicking on it. A right click brings up its context menu. For data
objects and modules, the list contains the list of available items that
can be connected. For folders, the context menu allows you to rename or
delete the folder, add a new folder below, and possibly import data.
For objects that have an associated colormap, e.g.,
an OrthoSlice with Mapping Type Colormap, a colormap icon is shown in
the Explorer. A right click on the icon brings up the standard colormap
context menu, a left click brings up the colormap editor.
For objects that have a slice number, e.g.,
OrthoSlice, the slice number is shown in the Explorer.
One important change in the GUI between the graph
view and tree view is how input connections are handled. In the graph
view, you could use the mouse to interactively change the connections
between data objects and modules directly in the Pool. In the tree
view, the input connections are handled as ports in the Properties
Area.
Example: You have loaded motor.am and you connect an
OrthoSlice to it. In the OrthoSlice control panel in the Properties
Area, the first port is a Data port showing that motor.am is connected.
If there are other data objects in the Pool/Explorer
that could be connected to the OrthoSlice, they will be listed in the
data port's pulldown menu. You can select one of them to connect the
OrthoSlice to a different data object.
Currently,
there are two "templates" that control the organization of the tree
view: a default template for most Avizo users, and a "seismic" template
for users who have an AvizoEarth license for working with geoscience
data. See the "Avizo Earth Edition" topic below for more details on the
seismic template.
Pool -- The new "Duplicate mode" toggle
The new "Duplicate mode" toggle is handy if you will
be attaching multiple modules of the same type to a data object and you
want the modules to have the same initial port values. If the toggle is
on, the port values of the first module will be
used to intialize the port values of subsequently attached modules.
Example: Attach an Orthoslice to your data object
and set the Mapping type to "Colormap" and the colormap range to 0-3.
If you attach another Orthoslice to the same data object, its Mapping
type will be "Colormap" and the colormap range will be 0-3.
Pool -- The new "Auto adjust range of colormaps"
toggle
The new "Auto adjust range of colormaps" toggle
allows you to request that Avizo automatically adjust the range of a
colormap to correspond to the data range of the data set it is
connected to. Note that this feature only applies to the geoscience
modules: seismic slices Inline, Crossline, TimeSlice, etc.,
CroppedVolume, and SeismicSurfaceView.
Segmentation Editor
The Segmentation Editor has been enhanced with the
following new features:
- Views can be zoomed individually. If the
"Current viewer" button is checked, then the zoom buttons apply to the
currently active viewer rather than to all views.
- Data windows can be adjusted individually. If
the "Current viewer" button is checked, then the data window tool
adjusts the window of the currently active viewer rather than all
views.
- Colormap support. The colormap of the image can
be changed from the default gray ramp to another colormap by pressing
the "Select colormap" button.
- Square brush. The "Square brush" option will
paint, as the name suggests, a square region instead of the default
circular region. The other brush options will work with it as expected.
- Brush range can be limited. If the "Limited
range only" option is selected, the brush will paint only pixels whose
values fall between those in the range slider.
- Line tool (part of brush tool). It is possible
to fence an area defined with line segments by pressing {\em Alt}, and
clicking successively to points with the left mouse button (holding
down the {\em Alt} key all the time). Successive points will be
connected with straight line segments. To finish interaction, release
the {\em Alt} key and click a last time. The contour is then closed,
and the lines traced over with the brush.
Colormap Editor Alpha Curve
The Colormap Editor has been enhanced to allow
editing of the colormap alpha values using an alpha curve that you can
shape interactively with the mouse. Previously the alpha values could
only be edited using "keys".
This feature is accessed via the Edit->Show
Alpha Curve item of the Colormap Editor dialog. Unlike most attribute
settings in Avizo, this setting is persistent across Avizo sessions.
CollectiveTCL
This is a new module for executing a Tcl command on
objects in the Pool. You can specify that it be applied to all visible
objects (i.e., not hidden), all selected objects, or all objects of a
specified type.
ExtractSurface
This
new module allows you to extract surfaces displayed by one or more
modules, e.g., SurfaceView, GridVolume, HexaView. In order to extract a
surface, you will first select the parts of the object you are
interested in using the selection mechanisms provided by the input
modules. For example, in case of a SurfaceView module different parts
can be selected via the materials menu, via the selection box (buffer
show/hide), via 2D lasso selection (buffer draw), or by selecting or
deselecting individual triangles with the mouse. All visible triangles
will be extracted into a new surface object when you press the Apply
button.
PlotSpreadSheet
Some modules, such as MaterialStatistics, create a
spreadsheet of values. The new PlotSpreadSheet module allows you to
display the values as a plot in a separate window. You can select a
single column of data to be used for the X axis values, and one or more
columns to be plotted on the Y axis.
ViewerPlot
Some modules, such as Histogram and LineProbe,
create a plot in a separate window. The new ViewerPlot module allows
you to instead display the plot within the viewer window. You can
control the placement, size, transparency, and other attributes of the
plot within the viewer.
Demo Framework
The Demo Framework is a framework for organizing
your demos. It incorporates four major parts:
- A directory and file structure containing the Avizo
scripts to execute the demos, their description, and their data. The
directory structure may realize a grouping and can also resemble a
project structure of the demos.
- Several scripts to select demos from the demo
collection, utilities to download data from remote servers, helper
scripts for demo steering, etc.
- Demo GUI, an editor for conveniently selecting and
changing demo collections.
- DemoSequence, an Avizo script object for driving
the selected demos.
The documentation for the Demo Framework is accessible from the home
page of the Avizo help browser.
New Avizo XTeam Pack
The new, separately licensed AvizoXTeam enables
remote users to work efficiently together by sharing a common Avizo
session.
Avizo XTeam pack is based on a client/server
architecture. The server handles the list of opened collaborative
sessions. When a user connects to the server, he can create his own
session and join as the initial operator. Or he can join an existing
session as a spectator.
The collaborative session is directed by a single
operator who can create new modules in the Pool, change ports, and
interact with draggers in the 3D view. The other collaborators are
spectators that watch what the operator is doing. They can be allowed
by the operator to choose their own viewpoint. Once the operator has
finished his work, he can close the session or give his operator
privileges to another collaborator. When the operator transfers his
privileges, he becomes just another spectator.
For more information, see the Avizo XTeam User's Guide which is
accessible from a link on the home page of the Avizo help browser.
Avizo Earth Edition
Mercury is proud to announce Avizo Earth Edition,
which includes a much expanded feature set for the geosciences.
For your convenience, this new edition is unlocked
by a single license, AvizoEarth, which unlocks the following packs:
- XLVolume Pack,
- XReadSEGY Pack
and which also enables the geoscience GUI. The new
features and enhancements, including the geoscience GUI, are
highlighted below.
Pool -- Tree view display of objects in the Pool
This provides a more familiar user interface to
those in the Oil & Gas field, and can be more convenient when
working with large numbers of data sets and modules. Its new features
are described in further detail above in the Avizo section.
In tree view mode, the Pool pane and the Pool menu
are relabeled "Explorer".
A geoscience "template" for tree view includes
predefined folders for 3D surveys, horizons, faults, etc.
Note: A folder for wells is shown in the geoscience
template, but import of well data is not yet implemented.
On-screen compass
It indicates from which direction you're viewing the
survey data.
Viewer toolbar buttons
They allow you to view your data from north, south,
east, or west.
New options in the Layout tab of the Preferences
dialog
They allow you to select tree view or graph view,
geoscience template or default template, and the position of the
compass.
The SEG-Y Wizard
It now has a help button for easy access of its
corresponding help topic.
FenceSlice
New module for drawing fence slices.
FaultSticks and FaultSticksView
FaultSticks is a new kind of data object created
when you load fault stick data. It can be viewed with the new
FaultSticksView module, which allows you to specify a line width scale
factor and line color for the fault sticks.
SeismicSurfaceView
New module for drawing seismic surfaces using a
specified draw style and specified colormap.
SeismicSettings
This module allows you to set global seismic
attributes, including the coordinate system (UTM or
crossline/inline/time), a time (Z) scale factor, a default seismic
colormap, and a default surfaces color map. This module is always
present in the Pool if an XReadSEGY license is found.
Note 1: Previously the global time (Z) scale factor
was specified in a port of the LDA seismic object, e.g., your_data.lda.
Note 2: This global scale factor applies to *all*
visualizations in the viewer, not just seismic visualizations. Normally
seismic and non-seismic data sets are not visualized together so
normally this should not cause a problem.
Shared Colormap
Seismic data objects, e.g., your_data.lda, now have
a new port, Shared colormap, which specifies the colormap to be
associated by default with all of the visualization modules attached to
the data object.
Pool/Explorer
The new "Auto adjust range of colormaps" toggle
allows you to request that Avizo automatically adjust the range of a
colormap to correspond to the data range of the data set it is
connected to. Note that this feature only applies to the geoscience
modules: seismic slices Inline, Crossline, TimeSlice, etc.,
CroppedVolume, and SeismicSurfaceView.
Geoscience GUI
The geoscience GUI is enabled by default if you have
an AvizoEarth license. Components of the geoscience GUI include the
following:
Tree view display with the geoscience template
selected:
- Display of compass in viewer
- Viewer toolbar buttons for selecting view from
north, south, etc.
- Colormap editor configured to use alpha curve for
editing transparency
Each of these items can be reset to their
non-geoscience state if desired.
Avizo Earth Edition User's Guide
The new "Avizo Earth Edition" User's Guide
introduces you to many of the geoscience features. Its link appears on
the home page of the Avizo help browser.
