3dfier - v1.4.0

• implement and add maxoutlierfraction parameter to Bridge and Road classes. This fixes the creation of unrealistically steep surfaces for roads an bridges due to a bad polynomial fit during outlier detection and feature flattening.

3dfier - version 1.3.0

Version 1.3.0 contains some improvements and bug fixes. - Update nlohmann-json to version 3.7.3 - Support for CityJSON version 1.0 with EPSG metadata - Read CurvedPolygon and MultiSurface and stroke curves (use options:maxanglecurvepolygon for setting maximum stoke angle) - CSV ouput remove trailing comma and change delimiter from semicolon to comma - Improve OBJ LoD0 creation - Output license information of used libraries with --license option - Destroy GDAL feature after reading and free memory used by wkt string. - Correct parsing of requested extent from configuration file - Add code comments - paths for files in YAML can be all in unix (/) and relative paths are supported. Works under Windows too, so one YAML file to unite them all is now given as example. - added STL output, useful for the CFD community. Only text-based STL now, binary to follow.

3dfier - Version 1.2.2

This is the second hotfix for version 1.2, it fixed an issue in the 3d polynomial plane fitting used in the outlier filtering. This fitting iteratively removes vertices with the largest outlier. The first vertex is used to normalise xy-coordinates, when filtering the first vertex the offset was lost and results were off.

3dfier - Version 1.2.1

We added a seperate thresholdbridgejump_edges in this release. With this threshold you can set the height difference upto which bridges are merged with adjacent (road) objects. Some small issues were found in the greedy insertion code, in the case of adding a lidar point on an edge now all exceptions are handled.

3dfier - Version 1.2 -> Change to laslib

This is version 1.2 released after three months of improving functionality. - Since this version we changed from liblas to laslib since liblas was creating rounding errors in floating points. Since the change to laslib the precision even improved. - Many improvements in the greedy insertion code for filtered TIN creation making the code way more stable. We are now also catching insertion of lidar point on top of polygon contraint (both vertex and edge). - Updated CGAL to version 4.12

3dfier - Version 1.1

This release contains lots of small fixes for creation of 3D model of The Netherlands. - PostGIS writing memory consumption is solved. - Improved error handling for GDAL reading/writing - Now writing x-y-coordinates with 3 digits and z-coordinates with 2 digits for OBJ/XML output formats. - By default the settings for Roads and Bridges contains filter_outliers = true and flatten = true. When the point cloud contains lots of outliers this improves reconstruction but in rare cases results are worse due to the polynomial surface fitting.

3dfier - Version 1.0

Finally we arived at the point that 3dfier is ready for its release of version 1.0!

In the last months we tested lots of datasets and solved lots of small issues and some bigger ones.

Bigger issues solved; - Creation of bridges (which is quite the chalenge since there is no 3D points below a bridge). We have found that with the proper input for bridges the output is satisfactory. - Roads having outliers when 3D points are misclassified or when close to bridges (if bridge points are taken into account for roads). We implemented an iterative Least Squares 3D quadric surface fitting for removing outlier points. In the yaml there is a setting to remove outliers and to completely flatten the roads based on the fitted surface model.

After a long time of development we are proude to introduce 3dfier version 1.0 Release Candidate 1. There has been allmost 9 months of development and lots has changed. We believe 3dfier is now at a level it earns the right to be called Version 1.0.

3dfier - Version 0.9.7

Changes are mainly in filtering las/laz points since there is a bug in libLAS when reading next point while using a filter. This release implements the filters by itself so each point is read from the input file. Advantage is that now the point percentage bar is nicely running up to 100% again.

3dfier - Version 0.9.6

Update: The release had some issues with PostGIS writing and building with GDAL < 2.0 which are now solved.

This release has performance increase for writing files in OBJ and CityGML (file writing is 10-15x faster).

Included is the option for writing CityGML into separate files by using CityGML-Multi as output format. Splitting is done using GDAL->GetLayerName() thus not always related to the input filename.

Included is writing to PostGIS database both in a single or multiple tables (PostGIS or PostGIS-Multi as output format). The PostGIS connection string as used in GDAL is used as output filename in the command line argument (3dfier config.yml -o "PG: host=localhost dbname="3dfier" user=username").

3dfier - Version 0.9.5

This release is branded 0.9.5 due to its vast amount of improvements. The main difference is in performance, by removing some of the boost::geometry code and implementing a ray tracing algorithm for point in polygon, a performance boost of around 40-60% has been registered.

Other improvements are catching LAS/LAZ reading errors and better error handling in reading polygons.

3dfier - Version 0.8.2

This version includes improvements on reading LAS/LAZ and extent selection for polygon files: - Checking the bounds of the header to intersect the extent of the polygons to skip file - Checking if the point is within the extent of the polygons - Using liblas filtering instead of if-statements for Classification, Bounds and Thinning - All LAS/LAZ files from a directory can now be imported by using directory/with/files/*.las or directory/with/files/*.laz (subfolders are ignored) - YAML file can now have options: extent: xmin, ymin, xmax, ymax which check the polgyon bounding box to intersect with the supplied extent

Other improvements; - A small fix for the IMGeo Nummeraanduidingreeks to crash the CityGML-IMGeo writing if conversion with GDAL was done improper. - Added a new bgt_pand.gfs file to fix the Nummeraanduidingreeks conversion in GDAL
