Face.CalculateStrokes Method
Parent Object: FaceDescription
Obtain the stroked or polygonal representation for the given chord-height tolerance.
Remarks
C++ clients needs to deallocate the pointers with CoTaskMemFree.Syntax
Face.CalculateStrokes( Tolerance As Double, VertexCount As Long, SegmentCount As Long, VertexCoordinates() As Double, VertexIndices() As Long )Parameters
| Name | Type | Description |
| Tolerance | Double | Input Double that specifies the maximum distance that the stroke can deviate from the smooth curve. This value is in centimeters. Smaller values can result in a much greater number of strokes being returned and will require more processing time to calculate.
The picture below illustrates how the chordal tolerance is used when creating a stroked version of a curve. The chordal tolerance defines the maximum distance a line can be from the actual curve.  |
| VertexCount | Long | Output Long that returns the number of vertices that were generated. This is the number of vertices that will be returned by the VertexCoordinates argument. |
| SegmentCount | Long | Output Long that returns the number of segments that were generated. |
| VertexCoordinates | Double | Output array of Doubles that contains the coordinate locations of the vertices. The values are defined in x, y, z order within the array and represent coordinates within the model space of the faceted object. |
| VertexIndices | Long | Output array of Longs that are used as index values to index into the vertex coordinate list. The first coordinate in the vertex coordinate list is index 1. |
