py3dtiles.tileset.content.pnts_feature_table.check_array_size(array: ndarray[Any, dtype[float32 | uint16 | uint8]], semantic: SemanticPoint, nb_points: int) → None[source]#

This function checks if the size of the given array is correct according semantic and nb_points. If not, it raises an InvalidPntsError exception.

py3dtiles.tileset.content.pnts_feature_table.check_semantic_type(semantic: SemanticPoint, category: SemanticCategory) → None[source]#

This function checks if the category of the semantic is the same as the parameter category. If not, it raises an InvalidPntsError exception.
