Changes from Stradwin 5.1 to 5.2
Added a new reader and writer for surfaces stored in the PLY format, which has more external support than the VRML format, and is also faster to load.
Added the ability to create distinct surface patches by manually outlining regions on previously defined surfaces. This is particularly targeted at cortical bone mapping for cartilage or other non-closed surfaces.
Improvements to cortical bone mapping
It is now possible to run this on data with values less than 0 (e.g. MRI).
Cortical measurements can now be smoothed without necessarily filling in missing measurements.
The colour range for density values now has an adjustable offset rather than always starting from 0.
The default format for saved measurements has been changed to increase documentation and flexibility.
There is now visual feedback when using a non-zero line width.
The use of thresholds in thickness calculation has been improved and extended to the detection of inner and outer layers as well.
Searching for an additional 'outer' cortical layer is now enabled by default.
Data can now be compounded onto surfaces either from inside or outside the surface.
The ends of surfaces are now interpolated when within the data by default.
It is now possible to load the subset of DICOM images in a directory that all have the same image size as the initially selected file.
For ultrasound data stored in RF format, the basebanding frequency is now stored separately in the probe configuration file, rather than presuming this is the same as the probe centre frequency.
Loaded surfaces can now be painted with the 3D data by using the compound option on the draw task page.
A new 'v' key has been added to the 3D window to enable visualisation and editing of the current viewpoint.
A new 'c' key has been added to the 3D window to toggle display of the centres of gravity of surfaces.
Stradwin can now correctly load DICOM files which have been stored in big-endian format.
Cortical thickness mapping when using thresholds now correctly fails when no threshold is detected in the data.
Fixed a bug which caused incorrect image scales in the situation where a sequence of images (with no scales) were loaded, scales were then manually added, and then a subset of the original frames were exported in stradwin format.
Corrected a crash related to the extrapolation of surface caps if the last surface contour was particularly large.
Corrected the display of the frame and reslice opacity in the 3D window.
The use of smoothed lateral estimates in elastography is now turned off by default since this option can in some instances cause a crash.
