      [ADD #361] Added feature to delete small connected voxel groups · df86ea5c
      aschwarzkopf authored
       * The algorithm is intended to grouup voxels that have surfaces with the same
       * normal vector. This feature helps to remove small groups. Obviously trees
       * by nature have points that lead the Principal Component Analysis to
       * surfaces that have very different Eigen Vectors of the smallest Eigen Value
       * that is the normal vector in the case of surfaces.
       *
       * Other feature: Removing voxels by a point count per voxel.

      [ADD 361] Prototypic surface detection OpenWalnut module · 7180d123
      aschwarzkopf authored
       * The new module firstly puts point data into a voxel grid. For each of these areas
       * the Principal Component Analysis is run. For each voxel the Eigen Vector of the
       * smallest Eigen Value is taken. In the case of surface kins data it's the normal
       * vector. In the last steps voxels with the similar vector are grouped.
       * Currently the region growing often bleeds over through many surfaces.

      [ADD #360] Added prototypic module to remove tree structures. · 41b8f04c
      aschwarzkopf authored
       * This algorithm puts input point coulds to a voxel grid and applies the Principal
       * Component Analysis to each of these areas. It's calculated how isotropic voxels are.
       * Either planar voxels have the blue color and isotropic ones are red. There's a
       * feature to cut avay voxels from the output triangle mesh for the view. You can either
       * set the minimal point count per voxel or the quotient of the smallest Eigen value over
       * the biggest one as the maximal isotropic level criteria.

      [ADD #309] Added some point output features and bugfixes. · 258944b5
      aschwarzkopf authored
      Following bugfixes new features:
        - Points group selector plugin: Can output selected buildings as
          WDataSetPointsGrouped in order to be able to view data in other plug-ins
        - Elevation image export plugin: Features to switch elevation display
          in triangle mesh height and color.
        - Fixes in documentation and few code cleanup.

      [ADD #309] Added colors to building point groups and direct elevation image display. · c04b1e87
      aschwarzkopf authored
      The buildings detection plugin generally was a mix of many things. These things of
      it were split up into these plutins:
        - Elevation image export
        - Points group selector which transforms building groups into a voxel structure
          and exports it to a triangle mesh.
      
      Added features:
        - Elevation image can be output in a triangle mesh
        - Elevation image (file and triangle mesh output) and building outline got colored
          building outline
      
      Code style:
        - Fixed prooblems with documentation (make doc)
        - Purged last code style (make stylecheck)

      [ADD #309] Added Simplistic Building detection feature. · 9006f304
      aschwarzkopf authored
      Some simplistic algorithms are done in order to group buildings. Evaluation:
        + Important data structures as Octree and Quadtree are implemented with important functions
        + Grouping neighbor voxels runs even if still not 26-neighborship (few steps required)
           + Algorithm can easily be transferred to the quadtree set.
        + First new plugin for cutting of outlier points using the algorithm that calculates
          figuring out cube connectivity. Other points are cut off that don't belong to the
          largest voxel group
        - Possibly vaporized effort
            - The algorithm that takes relative elevation minimums has problems detecting low buildings.
                - Probably the algorithm won't be taken
                + The great deal of the code amount used for it can be very useful for the final code.
            + It's easy to differ trees from buildings
                - Not thought to the end to differ trees that are very close to buildings

      Done few very first steps for building detection:
        - Areas that contain data set points, are outlined by octree nodes
        - Ability to draw that outline as boxes in order to be able to draw very
          huge las files at all.

      Just started very first building detection implementation steps:
        - Transforming point data to octree nodes
        - Ability to display LAS data as boxes, but without color intensity display.
          Now you don't need vast amount of RAM (32GB for a 500MB las file) and GPU
          memory to be able to display larger las files at all.
