Function Documentation

evaluate_filter()

auto rux::filters::evaluate_filter	(	const std::string &	filter_expr,
		reusex::ProjectDB &	db,
		size_t	expected_size ) -> reusex::IndicesPtr

Evaluate filter expression and generate Indices.

Parameters

filter_expr	Filter expression string (e.g., "planes in [1,2]")
db	ProjectDB containing label clouds
expected_size	Expected point cloud size for validation

Returns

Indices of matching points, or nullptr if filter_expr is empty

Exceptions
