      geom/m43600: intra geometry occupancy prediction · 89fae502
      David Flynn authored
      This commit provides a method to predict the child occupancy bits of a
      node based on the node's 26 neighbours.  The prediction is used to
      contextualise coding of each occupancy bit.
      This tool requires the use of the occupancyAtlas for neighbour lookup.
      NB: a restriction in the current implementation requires that the
      atlas size is at most 8³.

      attr/m43780: use dual lut coder for transform coefficients · fc813708
      Khaled Mammou authored and David Flynn's avatar David Flynn committed
      This commit replaces the m-ary coding of transform coefficient values
      with a binary coding using the dual-lut coder.
      Reworked to include a bug fix where the maximum attribute symbol value
      used by the dual lut coder is 64 rather than 255

      refactor: move common constants to constants.h · a298b199
      David Flynn authored
      This commit moves various constants from PCCTMC3Common.h to a new
      constants.h.  Hard coded values of constants have been replaced with
      their symbolic name.

      m43953/hls: implement sps, gps, aps syntax structures and tlv fileformat · faf569e8
      David Flynn authored
      This commit rewrites the codec high-level syntax:
       - the bitstream is divided into "bricks" (akin to an AVC/HEVC
       - sequence, geometry and attribute parameter sets describe the coding
         parameters in use generally and for a specific brick.
       - marshalling the bitstream payloads to a file format is achieved using
         a type-length-value encoding scheme.
      Additionally, the triSoup bitstream scale and translation values have
      been unified with (replaced by) the octree counterparts.  For
      compatibility, existing command line parameters continue to function
      as before.
      NB: this commit does not incorporate flexibility in the decoding order.
      The decoder requires the bitstream to be presented in a fixed order.

      m42634/tmc1: add mode to invoke TMC1 geometry compression · c3d42c2d
      Philip A. Chou authored and David Flynn's avatar David Flynn committed
      This commit does not add the triangle soup geometry compressor to TMC3,
      rather.  Rather, it adds a means to call out to TMC1 binaries to perform
      the compression, integrate the results into the bitstream.
      Attribute compression is performed natively by the TMC13 codec.

      use program-options-lite for command-line and config handling · 5529c24e
      David Flynn authored
      This commit replaces the previous command-line argument parsing with
      program-options-lite, which additionally serves as a simple config-file
      A table based configuration of options provides in a single place
      option naming, help text, and default values.
      Side effects of this change are to:
       - adds further error checking for unknown arguments (warning only), parse
         failures, required options.
       - replace the default constructor of Parameters,
         PCCAttributeEncodeParamaters, and PCCAttributeEncodeParamaters
         with defaults in args handler
       - updates the type of Parameters::mode & ...::colorTransform to be more
         more descriptive.
