CSGModel

CSGModel(tree: dict, name: str, **kwargs)

Model for shape generation through Constructive Solid Geometry.

Parameters:

• tree (dict) –

  The CSG tree as a dictionary mapping operations to operands. The operations have to be one of {"union", "intersection", "difference"}. The operands have to be lists of shapes or lists of dicts that are CSG trees themselves. At every level of the tree, there can be only one operation.

• name (str) –

  The name of the model.

Attributes:

• tree (dict) –

  The CSG tree as a dictionary mapping operations to operands. The operations have to be one of {"union", "intersection", "difference"}. The operands have to be lists of shapes or lists of dicts that are CSG trees themselves. At every level of the tree, there can be only one operation.

Functions

add

add(shape: Shape) -> tuple[int, int]

Add a shape to the underlying OCC model.

Parameters:

• shape (Shape) –

  A geometric shape.

Returns:

• tuple[int, int] –

  A "dimtag", a dimension and a tag that together uniquely identify the shape in the OCC model.

compute_tree

compute_tree() -> None

Comute the compound shape resulting from the operations on shape primitives in the tree.

Returns:

• None –
