texture
Create a new set of texture coordinates by contour stretching
the polygon inputs onto a "surface" pinned on the contour of the
polygon inputs. A proper contour of the polygon inputs must exist
to guide the contour stretching process.
oReturn = GenerateUVSetByContourStretching( InputObjs, PropertyName, [ContourStretchingMethod], [MaintainAspect], [CornerPoints] ); |
Returns an XSICollection object that contains two XSICollection objects. The first is a list of the created properties. The second is a list of the created operators.
| Parameter | Type | Description |
|---|---|---|
| InputObjs | String | List of polygon inputs to
which the polygon UV texture coordinate contour stretching operator
is applied.
Default Value: Selected objects |
| PropertyName | String | Name suggestion for the texture coordinates. |
| ContourStretchingMethod | siTxtContourStretchingMethod | Polygon cluster contour stretching method.
Default Value: siContourStretchingWalkingOnMesh |
| MaintainAspect | Boolean | Whether to maintain aspect ratio.
Default Value: False |
| CornerPoints | String | Optional list of point
inputs that define corners on the contour of the polygon inputs.
Each input may contain from 0 to N points and only up to the first
4 points of each will be used to define corners. If the input
corners are not part of the contour of the polygon inputs then they
are ignored.
Default Value: Empty. Corners are derived automatically internally. |
