For all features listed in FeatureFeatureFeatureFeaturefeature a minimal and maximal threshold must be specified in MinValueMinValueMinValueMinValueminValue and MaxValueMaxValueMaxValueMaxValuemaxValue. This range is then used to select all given 3D object models that fulfill the given conditions. These are copied to ObjectModel3DSelectedObjectModel3DSelectedObjectModel3DSelectedObjectModel3DSelectedobjectModel3DSelected. For logical parameters (e.g., '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", ...), MinValueMinValueMinValueMinValueminValue and MaxValueMaxValueMaxValueMaxValuemaxValue can both be set to 'true'"true""true""true""true" to select all 3D object models that have the respective attribute or to 'false'"false""false""false""false" to select all that do not have it. MinValueMinValueMinValueMinValueminValue and MaxValueMaxValueMaxValueMaxValuemaxValue can be set to 'min'"min""min""min""min" and 'max'"max""max""max""max" accordingly to ignore the respective threshold.

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