Version 1.5: Date of Release: July 2013
Summary of Major Changes
- A comprehensive ability to model trishear at fault tips has been introduced. Even though only one new menu item was added, all Interpret and Structural Modeling functions were changed to handle trishear correctly.
- We have added a comprehensive ability to determine displacements and estimate a detachment using the Area-Depth Graph method. Area-Depth Graphing is fully integrated with Interpret functionality so that results vary interactively as you modify your interpretation.
- In the Animate Model function, fault shear axes are no longer displayed above the depositional surface during animation. The Animate function has also been upgraded to animate structural models for faults that have trishear enabled. In this case, the dynamic position of the propagating fault tip is shown during animation.
- Graphics drawing mode has been changed to use anti-aliasing which results in smoother drawing with no apparent reduction in performance. In parallel, a robust method of point reduction was implemented for modeled structural surfaces.
- Modify has been changed so that points are highlighted and become selectable only if the cursor is sufficiently close (20 pixels).
- Structural Modeling/Identify Fault Errors and Restoration/Display Intersections have both been changed so that dynamic labels are show only when the cursor is sufficiently close (20 pixels) to a Fault Error Point or Horizon-Fault Intersection Point.
- The stroke thickness of displacement vectors in Show Displacement has been increased for clarity.
- The number of operations that can be undone or redone was increased from 20 to 30.
- The Help System was improved to be universally context specific (the Help Browser opens to the page describing the current or most recent operation).
- In previous versions, Restore and Zoom would fail if your image had been calibrated with horizontal coordinates that decreased from left to right. This bug has been fixed. All parts of the code work correctly if the true world horizontal coordinates decreases from left to right.
- In Version 1.4, the pixel limit in Display Settings could be reduced to a default of 16 megapixels, even if the current displayed image contained more pixels. This could subsequently cause Extend Image to behave incorrectly. This bug was fixed by making the minimum allowable limit in the Display Settings dialog to be the greater of the current display size and 16 megapixels.
- In previous versions there was a bug whereby recalibrating a structural model whose surfaces were not deformed could cause footwall and hangingwall reference depths to vary by a small double precision rounding amount. Consequently you could not delete a top surface from the model in some circumstances. This bug was fixed by preserving true equality of hangingwall and footwall reference depths during recalibration.
Revision 1.5.1: July 2013
- This was an interim non-production release fixing a bug in the Area-Depth displacement computations in the the case where Intercept Area is non-zero.
