This release adds the build_processor_strategy.proto, a supporting definition file for build processor software that generates OpenVectorFormat data. The build processor strategy is a collection of settings, defined using OVF objects. It is used in conjungtion with a slicer software to prepare build jobs for the LPBF process, using material specific parameters.
The build processor strategy defines a collection of ParameterSet objects. A ParameterSet consists of three things:

  1. LPBFMetaData: the type of vector block the settings apply to, e.g. Support or Part, InSkin, UpSkin or Downskin etc.
  2. ProcessStrategy: the settings used to slice, e.g. layer thickness, hatch distance or pattern
  3. MarkingParams: The settings of the optics system, e.g. laser power, exposure speed etc.
    Also added in this release are bounding boxes in the meta data on job, workplane and vector block level to utilize when merging OVF data to jobs, and a preferred color definition to be used by viewers.

The new features are used in the C# reference implementation in the OpenVectorFormatTools for merging and parametrizing build jobs from multiple OVF source files.
