ModifyUVSetByContourStretching
Modify an existing 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 = ModifyUVSetByContourStretching( InputObjs, TextureProjection, [ContourStretchingMethod], [MaintainAspect], [CornerPoints] ); |
Returns an XSICollection that contains 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. |
| TextureProjection | String | Texture space to modify. |
| 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 boundary of the polygon inputs.
Each input may contain from 0 to N points and only up to the first
4 points of each input 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. |
