Property | Description | Default Value(s) | Restrictions |
Boundary Vertex Deletion (BoundaryVertexDeletion) |
If this property is set to 1, then vertices on the boundary of the dataset can be removed. Setting the value of this property to 0 preserves the boundary of the dataset, but it may cause the filter not to reach its reduction target. | 1 | Only the values 0 and 1 are accepted. |
Feature Angle (FeatureAngle) |
The value of thie property is used in determining where the data set may be split. If the angle between two adjacent triangles is greater than or equal to the FeatureAngle value, then their boundary is considered a feature edge where the dataset can be split. | 15 | The value must be greater than or equal to 0 and less than or equal to 180. |
Input (Input) |
This property specifies the input to the Decimate filter. | The selected object must be the result of the following: sources (includes readers), filters. The selected dataset must be one of the following types (or a subclass of one of them): vtkPolyData. |
|
Preserve Topology (PreserveTopology) |
If this property is set to 1, decimation will not split the dataset or produce holes, but it may keep the filter from reaching the reduction target. If it is set to 0, better reduction can occur (reaching the reduction target), but holes in the model may be produced. | 0 | Only the values 0 and 1 are accepted. |
Target Reduction (TargetReduction) |
This property specifies the desired reduction in the total number of polygons in the output dataset. For example, if the TargetReduction value is 0.9, the Decimate filter will attempt to produce an output dataset that is 10% the size of the input.) | 0.9 | The value must be greater than or equal to 0 and less than or equal to 1. |
