IX2D
2-Dimensional Gravity/Magnetics Interpretation Software
IX2D is an interactive 2-D gravity
and magnetics forward modeling and inversion package based on polygonal
models which can be truncated asymmetrically along strike. It is basically a
port of MAGIX XL to Windows, complete with translation of MAGIX
functionality to a true Windows interface.
To
evaluate this package, download the tutorial and run it. It is a PowerPoint
PPS file. Then, download and install the software and run it with the demo
data set. Be sure to open and peruse the HELP file and PDF manual. Contact
Interpex with any questions.
Features Include:
-
Real-time forward
modeling while moving vertices, moving or rotating bodies.
-
Inverse modeling with
selected parameters.
-
Control over free
parameters.
-
Locking together of
vertices.
-
User friendly
prevention of illegal bodies.
-
Hotkeys allow quick
changes to graphics - show locks, free vertices or color fill.
-
Toolbar buttons offer
quick access to most-used functions.
-
Virtually no limit on
size of data or model.
-
Automatic and
user-specified labels.
-
User-specified line
colors.
-
Annotated color fill
for body parameters.
-
Spreadsheet data
editors with copy & paste.
-
Spreadsheet model
editors.
-
Optional grid lines
on display.
-
ASCII File import and
export of data, synthetics and models.
-
Import of MAGIX Plus/MAGIX
XL files.

sample screen with a synthetic magnetic model and data. This model contains
two dyke-like bodies and several layers.
Data entry options:
-
Import of data from
flat ASCII files.
-
Import of data from
XYZ style ASCII files.
-
Import of data from
MAGIX ASCII files or of data and model from MAGIX binary files.
-
Copy and paste of
data from other spreadsheets into the data editor as shown below.

box.
Bodies and layers can be numerically edited and
numerically imported from MAGIX model files. They can also be copied from a
third-party spreadsheet and pasted into the grid in the dialog box.
Bodies and layers can be
edited numerically. They are checked for legality after editing.
Vertices can be locked to each other so they
move as a pair or group. For instance, in the salt dome model below, many of
the layers share vertex locations with those on the salt body and are locked
together so the salt dome can be moved somewhat and the layers will deform
to accommodate it.

data set with one body and many layers.
Vertices can be inserted graphically by
positioning the mouse and clicking. A modeless dialog allows for insertion
parameters to be changed during the creation of a layer or body. If Snap is
selected, the new position will snap to the vertex to which you are pointing
(cursor turns to a crosshair when pointing) and if Lock is selected, it will
be locked to said vertex. Attempts to insert illegal vertices can be ignored
or the vertex can be moved back to make it legal. The fix/free status of
each vertex is set as it is inserted.
Vertex insertion dialog allows for
changes as vertices are inserted.
Bodies are
closed by creating an additional edge between the last and first vertex.
Layers are bodies which are entered from left to right and closed
automatically with five edges at virtual infinity to the right, bottom and
left.
Bodies or layers can be entered using the mouse. This
shows layer entry.
Plot colors used to draw lines
can be user selected. The user also has control over the color fill range,
blue-to-red or red-to-blue and pixel density for the color fill.
Colors used to draw lines can
be user selected.
If an illegal model is created
when moving a body or vertex, the body and synthetic change color and the
cursor becomes a slashed circle indicating the problem. The body or vertex
reverts back to the last legal position when the mouse button is released.
Synthetic curve is updated as
the model is changed graphically with the mouse.
There are two kinds of labels; property
labels and text labels. Property labels show the properties of the model at
the arrow point (or center of label if no arrow is present). Text labels
show whatever text the user enters. Arrows can be created, moved or deleted
and labels can be moved or resized in the normal Windows manner.

options available for graphically editing the labels.
ASCII file output of the model, data or
synthetic data, as well as DXF, CGM and WMF graphics files are available for
export.
Licensing and Distribution
IX2D-GM is distributed as copy-protected software. The software can be
downloaded and it works fully only with the demo data supplied. The license
allows for a 30-day evaluation period. After the evaluation you are required
to purchase the package in order to continue using it. Purchase price is
US$1,499.00. Licenses are offered with your choice of USB or Parallel key.
