__init__(self: pyvcad_compilers.pyvcad_compilers.InpWriter) → None#
setProgressCallback(self: pyvcad_compilers.pyvcad_compilers.InpWriter, callback: object) → None#

Sets the progress callback for INP writing.

Parameters:

callback (callable) – Callback receiving (progress, message), where progress is a float from 0.0 to 1.0. Pass None to clear it.

write(*args, **kwargs)#

Overloaded function.

  1. write(self: pyvcad_compilers.pyvcad_compilers.InpWriter, path: str, root: pyvcad.pyvcad.Node, voxel_size: pyvcad.pyvcad.Vec3, config_path: str, use_volumetric_dither: bool) -> None

Writes the INP (ABAQUS Input) file to the specified path using linear brick elements.

Parameters:

  • path (str) – Output INP file path.

  • root (Node) – Root node to sample into brick elements.

  • voxel_size (Vec3) – Brick element dimensions.

  • config_path (str) – Material definition config path.

  • use_volumetric_dither (bool) – Use volumetric dithering for material sampling.

Example

>>> writer.write('/tmp/mesh.inp', root, pv.Vec3(1, 1, 1), 'configs/default.json', False)

  1. write(self: pyvcad_compilers.pyvcad_compilers.InpWriter, path: str, root: pyvcad.pyvcad.Node, voxel_size: pyvcad.pyvcad.Vec3, material_defs: pyvcad.pyvcad.MaterialDefs, use_volumetric_dither: bool) -> None

Writes the INP (ABAQUS Input) file to the specified path using linear brick elements.

Parameters:

  • path (str) – Output INP file path.

  • root (Node) – Root node to sample into brick elements.

  • voxel_size (Vec3) – Brick element dimensions.

  • material_defs (MaterialDefs) – Loaded material definitions.

  • use_volumetric_dither (bool) – Use volumetric dithering for material sampling.

Example

>>> writer.write('/tmp/mesh.inp', root, pv.Vec3(1, 1, 1), pv.default_materials, False)

Constructor. Creates a CrossSectionSlicer object.

Parameters:

  • root (Node) – The root node of the tree.

  • min (glm::vec3) – The minimum point of the bounding box.

  • max (glm::vec3) – The maximum point of the bounding box.

  • voxel_size (glm::vec3) – The size of the voxel.

Slices the geometry at a given z-height and iso value.

Parameters:

  • z_height (double) – The z-height at which to slice.

  • stitching_tolerance (double) – (Optional) The tolerance for stitching. Defaults to 1e-12.

  • colinear_tolerance (double) – (Optional) The tolerance for colinear points. Defaults to 1e-12.

ranges (List[Tuple[float, float]]): A list of tuples containing the lower and upper bounds of the material concentration to slice for. i.e. the ranges [0 to 0.5] and [0.5 to 1.0]. stitching_tolerance (double): (Optional) The tolerance for stitching. Defaults to 1e-12. colinear_tolerance (double): (Optional) The tolerance for colinear points. Defaults to 1e-12.Returns: List[Tuple[float, float, List[Polygon2]]]: A list of tuples containing the lower and upper bounds of the material concentration and a list of polygons that represent the cross section for the range.
