/** @brief DynamicFusion implementation

  This class implements a 3d reconstruction algorithm as described in @cite dynamicfusion.

  It takes a sequence of depth images taken from depth sensor
  (or any depth images source such as stereo camera matching algorithm or even raymarching renderer).
  The output can be obtained as a vector of points and their normals
  or can be Phong-rendered from given camera pose.

  It extends the KinectFusion algorithm to handle non-rigidly deforming scenes by maintaining a sparse
  set of nodes covering the geometry such that each node contains a warp to transform it from a canonical
  space to the live frame.

  An internal representation of a model is a voxel cuboid that keeps TSDF values
  which are a sort of distances to the surface (for details read the @cite kinectfusion article about TSDF).
  There is no interface to that representation yet.

  Note that DynamicFusion is based on the KinectFusion algorithm which is patented and its use may be
  restricted by the list of patents mentioned in README.md file in this module directory.

  That's why you need to set the OPENCV_ENABLE_NONFREE option in CMake to use DynamicFusion.
