SurfaceEvaluator.GetParamAnomaly Method
Parent Object: SurfaceEvaluatorDescription
Gets general information about the parameterization of the surface, such as whether or not it is periodic, singular, or unbounded in the parameter domain.
Syntax
SurfaceEvaluator.GetParamAnomaly( PeriodicityU() As Double, PeriodicityV() As Double, NumEndSingularitiesU As Long, SingularitiesU() As Double, NumEndSingularitiesV As Long, SingularitiesV() As Double, UnboundedParams() As Boolean )Parameters
| Name | Type | Description |
| PeriodicityU | Double | Output two element Double array that returns whether the surface is periodic in the U parameter direction. If the surface is periodic in U, the first array element is the period of the surface in U and the second element is the starting U parameter of the principle period. If the surface is not periodic in U, the first element is zero, and the second element is unused. |
| PeriodicityV | Double | Output two element Double array that returns whether the surface is periodic in the V parameter direction. If the surface is periodic in V, the first array element is the period of the surface in V and the second element is the starting V parameter of the principle period. If the surface is not periodic in V, the first element is zero, and the second element is unused. |
| NumEndSingularitiesU | Long | Output Double that returns the number of singularities in the U parameter direction. Valid values are zero to indicate no singularities, one to indicate one end singularity, or two to indicate a singularity at both ends. |
| SingularitiesU | Double | Output Double array that returns the U parameter values at which there is a singularity. If NumEndSingularitiesU returns zero, this argument is not used. |
| NumEndSingularitiesV | Long | Output Double that returns the number of singularities in the V parameter direction. Valid values are zero to indicate no singularities, one to indicate one end singularity, or two to indicate a singularity at both ends. |
| SingularitiesV | Double | Output Double array that returns the V parameter values at which there is a singularity. If NumEndSingularitiesV returns zero, this argument is not used. |
| UnboundedParams | Boolean | Input/output Boolean array of two elements that returns whether the surface is unbounded in the U or V parameter directions. |
