The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

Unreleased

Added

Changed

Fixed

Deprecated

Removed

0.7.0

Added

  • examples show in compas_viewer

Changed

  • significant refactor
  • generally a ~10x speed up was achieved in the refactor
  • slow ops have been vectorised with numpy, see _numpy_ops.py
  • COMPAS 2.x compatibility (data/from_data serialization, API changes)
  • igl dependency was factored out
  • earlier version had overlapping code paths (both a pure python and a cgal or igl version). these paths are harmonised to cgal
  • pure python calls have been replaced with cgal where ever possible
  • Type hints added throughout codebase
  • documentation was refreshened with modern mkdocs (none of that nasty rst litering the code)
  • pathlib migration (replaced os.path)
  • loguru replaced logging/print
  • Dataclasses replaced dicts
  • TOML-based config system (config.py + defaults.toml)
  • Medial axis infill via CGAL straight skeleton
  • CI modernization (py3.13 support, split workflows)

Fixed

Deprecated

  • igl

Removed

  • pure python paths; compas_cgal now is a hard dependency

0.6.2

Added

  • Costa surface on curved slicing example

Changed

Fixed

  • Fixed bug in sorting to vertical layers

Deprecated

Removed

0.6.1

Added

Changed

Fixed

Deprecated

Removed

0.6.0

  • Output nested printpoints

Changed

  • Updates in the visualization of PrintPoints
  • Added seams_align(next_path) to the standard planar slicing routine
  • Added unify_path_orientation back into the standard planar slicing routine
  • The way the normal and up_vector are calculated in the print organizers
  • Small updates in grasshopper visualization functions

Fixed

  • spiralize_contours: After function points are reprojected on the mesh
  • Curved slicing grasshopper file improved
  • Bug in post-processing of slicer paths generation

Deprecated

Removed

0.5.0

Added

  • Zenodo integration

Changed

Fixed

Deprecated

Removed

0.4.0

Added

  • Documentation updates
  • rdp libigl function (faster than the regular rdp)
  • sort_paths_minimum_travel_time: Function to sort paths by least travel time between contours in a layer

Changed

  • Changed the blend radius to add a blend radius of 0 for the first and last point of a path
  • Changed planar_slicing_cgal to add the possibility of slicing open paths with planar_slicing_cgal
  • Added the option to toggle generation of mesh normals on/off in create_printpoints
  • Added the possibility to slice only a certain section of the geometry by using slice_height_range in the PlanarSlicer

Fixed

  • Fixed some bugs in seams_align
  • Small bug in extruder_toggle
  • Small bug in simplify_paths_rdp_igl with printing remaining no of points
  • Bug in seams_smooth

Deprecated

  • close_paths in the BaseSlicer is unused for now, as it should not be necessary

Removed

0.3.5

Added

  • Add GH Python package to the installation

Changed

Fixed

Deprecated

Removed

0.3.4

Added

  • Alternative union operations in curved slicing
  • Function that adds wait time at sharp corners

Changed

  • Small improvements in gcode
  • Updated examples, and setup tutorials content (which is still empty - remaining to be filled)
  • set_blend_radius function assigns 0 to ppts that have a wait time (so that we are sure they are reached exactly)

Fixed

Deprecated

Removed

  • csWeightedUnion (outdated)

0.3.3

Added

Changed

Fixed

Deprecated

Removed

  • Removed libigl from the requirements, since it is not on pip we cannot have it in the requirements for now

0.3.2

Added

Changed

Fixed

Deprecated

Removed

0.3.1

Changed

  • Version to 0.3.1

0.3.0

Added

  • Zig Zag paths in print organization
  • Added automatic install on Rhino and GH when compas core is installed

Changed

  • Switched from compas_viewers to compas_viewers2
  • Updated csLoadPrintpoint.ghuser component on the data/gh_components and on the gh examples

Fixed

  • Bug in PrintPoint.get_frame() method (It was throwing a 0-division error when contours where situated on flat surfaces)
  • Bug in calculation of desired number of isocurves in interpolation slicer
  • Bug in safety points (their frame was not matching their point position)
  • Bug in tool plane in grasshopper visualization (Its axis did not match the compas_fab convention)

Deprecated

Removed

  • Feasibility parameter from printpoints visualization

0.2.1

Added

  • Bumped version to 0.2.1

Changed

Fixed

Deprecated

Removed

0.2.0

Added

  • Iterators through printpoints in PrintOrganizer
  • Iterative smoothing of attributes on printpoints (ex smooth velocities, orientations etc)
  • Export of (jsonable) PrintPoint attributes to json (in previous versions they were ignored upon export)

Changed

  • Added first layer in the slicing process that was previously removed
  • set_velocity function was split into separate functions depending on type (constant, by layer, by range, by overhang)

Fixed

  • Fixed bug on the calculation of the Printpoint frame (both on PrintOrganizer and on the gh visualization)

Deprecated

Removed

  • VerticalConnectivity from CurvedPrintOrganizer. This function does not need to be on its own class
  • Checking feasibility of Printpoints in PrintOrganizer (anyway it was a function left not-implemented in most PrintOrganizers). Might be re-introduced in the future but with more specific tasks
  • Planar slicing using MeshCut (and meshcut library from requirements)

0.1.3

Added

  • Fancy badges in the readme
  • Export to Gcode

Changed

Fixed

Deprecated

Removed

0.1.2

Fixed

  • Small bug in example 1 regarding the raft

0.1.1

Added

  • Generate raft functionality
  • is_raft parameter to the Layer

Changed

  • Simplify paths to exclude simplification of raft layers
  • Error raised when brim is attempted to be applied to a raft layer

Fixed

  • Small bug in print time calculation

2021-02-11

Added

  • UVcontours, UVslicer
  • VerticalLayersManager

Changed

  • Renamed the curved_slicer and all processes named after that (i.e. curved_preprocessor, curved_slicing_parameters, curved_print_organizer etc) to interpolation_slicer. These changes make this PR a breaking change
  • Reorganized the parameters folder. A lot of parameters where considered 'curved_slicing_parameters' although they were more general. So I broke those down into separate files. More parameters will be added in the future to those files

Fixed

  • Some documentation
  • Slicer printout_info bug

Deprecated

Removed

  • folder slicers.curved_slicing and all its contents

2021-02-03

Added

  • Reorder vertical layers functionality
  • Added z_height attribute to Layer and min_max_z_height to VerticalLayer

Changed

  • Extension of CHANGELOG
  • Changed naming of sort_per_vertical_segment to sort_into_vertical_layers
  • Changed naming of get_segments_centroids_list to get_vertical_layers_centroids_list

Fixed

  • Typo in wait time

Deprecated

Removed

2021-01-25

Added

  • ScalarFieldPrintOrganization as a slicing method
  • Transfer of attributes from mesh faces and vertices to PrintPoints (utilities/attributes_transfer.py). Added the necessary attributes in the PrintPoints. Also added an example (example_6_attributes_transfer.py) showcasing this functionality
  • ScalarFieldContours as a slicing method

Changed

  • Cleaned up the 'printout_info' methods in the BaseSlicer and BasePrintOrganizer
  • Refactored GradientEvaluation so that it can be applied in general for scalar fields, instead of just for interpolation fields
  • Bug fixes on CurvedSlicingPreprocessor
