Profile View

The Profile View provides an interface, where the polyhedral bodies are defined in sets of perpendicular cross sections running through the grid nodes. More profiles can be opened simultaneously, to get better overview over the geometry in both south-north and west-east directions respectively. Copying of the bodies or the whole cross section to the next or previous profile followed up by reshaping of the geometry speeds up the process of model creation. Profile View also shows curves of computed and/or measured and/or difference fields. More fields can be drawn transparently. Geo-referenced bitmaps could be imported into Mod3D, and drawn transparently to the Map View or Profile View. An example would be a geological map shown in Map View, or a seismic section displayed in a selected Profile View. Main geological units could be digitized in Map View, which are shown as check marks to achieve better orientation in the Profile View. The model definition system controls internally the consistency of the polyhedra geometries, or their topology in other words. The controlling system prevents overlapping or crossing of the polyhedra, simplifies reshaping of the existing bodies and reduces time needed for model creation.

Model Modification
SeeHow to Create / Modify the model? for detailed description.

Field Curves
Field curves on current profile are shown by default in following manner:
Modeled field for gravity and magnetics - solid line.
Modeled field for gravity tensor components - dashed line.
Measured field - cross symbols.
Difference field - dashed line.
See Field Toolbar for details how to show / hide field curves.

RMS & DRV Indicators
RMS indicator shows the Root Mean Square error of  the currently selected difference field(s). To show or hide the RMS indicator use command from menu Profile \ Show RMS.
DRV indicator shows the "fake derivative"  of  the currently selected difference field(s). To show or hide DRV indicator use command from menu Profile \ Show Derivative. Fake derivative is an approximation of the exact derivative and is computed as sum(dFld / dx + dFld / dy) over all points, where dFld=(Fld(i)-Fld(i-1)) and Fld(i) is the selected field in the i^th grid point.

Profile View floating menus.
Depending on where the user clicks the left mouse button, one can open following floating menus:

• Profile View menu. The default menu displayed, when user click out of any object.
   
  

  Menu Item	Shortcut	Description
  Next	N	Moves to the next profile.
  Previous	P	Moves to the previous profile.
  E-W Profile	H	Changes the profile orientation to East-West.
  S-N Profile	V	Changes the profile orientation to South-North.
  Show Previous		Shows bodies from prom previous profile on the current profile.
  Show Next		Shows bodies from next profile on the current profile.
  Jump to Extreme , Min, Max	E I A	Goes to the profile, where the extreme of the selected extreme field is located. To set the extreme field use command Profile \ Set Extreme Field.

  
  
  Body menu. Is displayed when user clicks over the body.
  
  

  Menu Item	Description

  Remove from Profile	Removes the body from the current profile.
  Edit Bodies	Activates Edit Bodies dialog.
  Body Creation Properties:	Use this command to set the body creation properties.
  Invert Density	Use this command to invert the density of the current body. From more details see: Invert Density Properties dialog.
  Density Inversion Properties	Set the settings for density inversion.
