v3.0
Allows you to navigate through the samples of the associated geometry. This method returns one Sample for each corresponding component in the collection. For example, if you have a SampleCollection containing 5 members and you call this method with the direction set to siLastComponent, the returned collection will contain 5 instances of the last sample in the original SampleCollection.
oReturn = SampleCollection.Navigate( Navigation ); |
| Parameter | Type | Description |
|---|---|---|
| Navigation | siNavigateComponentType | Select the direction of navigation. |
