The `/Zc:wchar_t-` option is not required to link with wide string methods in FileIO and Version. - SDK class no longer override the new and delete operators. This alows users of the SDK to override new. - Added support for new LAS 1.4 channels ScannerChannel, ClassFlags, and NearInfrared. - Added `ProgressDelegate::displayWarning()`, which is an optional override, it is called with informitive messages. - Added `PointInfo::init()` methods for building PointInfo object that have a subset of channels of a given PointInfo or PointData object. ### Version 1.1.3 (released December 2015) - Changed IO and FileIO classes. Subclasses of IO are now responsible for making `IO::open()` and `IO::close()` thread safe. This will only affect derived sub-classes of IO. See the file `lidar/IO.h` for more information. - Added a new GPS time channel. Replaced the `CHANNEL_NAME_GPSTime` macro with `CHANNEL_NAME_GPSTime_Week` and added `CHANNEL_NAME_GPSTime_Adjusted`. `GPSTIme_Week` is the number of seconds since midnight Sunday. `GPSTime_Adjusted` is the satellite GPS Time minus 1×109. ### Version 1.1.1 (released December 2010) - Turned the SDK library into a DLL and removed the static version. - Turned `Bounds::Huge` into a function `Bounds::Huge()`. ### Version 1.1.0 (released March 2010) - Revised file format (MG4 4.0.0.3) to support lossless floating point compression. - Added `PointInfo` class to replace the `(ChannelInfo[], length)` idiom. 1.0.1: `iter = reader->createIterator(bounds, 1.0, reader->getChannelInfo(), reader->getNumChannels(), NULL);` 1.1.0: `iter = reader->createIterator(bounds, 1.0, reader->getPointInfo(), NULL);` - Removed `LTLogMessage` functions. The information can be retrieved from the Error object. - Added experimental SWIG-based C#, Python and Ruby bindings to the contributions directory. - Robustness improvements to viewer application. ### Version 1.0.1 (released September 2009) - Revised file format (MG4 4.0.0.2) to support faster decodes. ### Version 1.0.0 (released July 2009) - This is the first public release of the LiDAR SDK. ![](https://www.extensis.com/hubfs/footer-cat-animation-final-compressed.gif) Pour vous récompenser d’avoir parcouru cette page jusqu’au bout, nous vous offrons ce joli chat.
