For all features listed in FeatureFeatureFeatureFeaturefeaturefeature a minimal and maximal threshold must be specified in MinValueMinValueMinValueMinValueminValuemin_value and MaxValueMaxValueMaxValueMaxValuemaxValuemax_value. This range is then used to select all given 3D object models that fulfill the given conditions. These are copied to ObjectModel3DSelectedObjectModel3DSelectedObjectModel3DSelectedObjectModel3DSelectedobjectModel3DSelectedobject_model_3dselected. For logical parameters (e.g., 'has_points'"has_points""has_points""has_points""has_points""has_points", 'has_point_normals'"has_point_normals""has_point_normals""has_point_normals""has_point_normals""has_point_normals", ...), MinValueMinValueMinValueMinValueminValuemin_value and MaxValueMaxValueMaxValueMaxValuemaxValuemax_value can both be set to 'true'"true""true""true""true""true" to select all 3D object models that have the respective attribute or to 'false'"false""false""false""false""false" to select all that do not have it. MinValueMinValueMinValueMinValueminValuemin_value and MaxValueMaxValueMaxValueMaxValuemaxValuemax_value can be set to 'min'"min""min""min""min""min" and 'max'"max""max""max""max""max" accordingly to ignore the respective threshold.

The parameter OperationOperationOperationOperationoperationoperation defines the logical operation that is used to combine different features in FeatureFeatureFeatureFeaturefeaturefeature. It can be either a logical 'or'"or""or""or""or""or" or 'and'"and""and""and""and""and".
