Detailed Description
- See also:
- Class NURBSCurve.
- Description:
- This class is available in release 2.0 and later only.
This class defines a dependent iso curve. U and V iso curves are dependent curves created along lines of constant parameter value of a NURBS surface. Note the difference between "Iso Lines", which are a display artifact, and "Iso Curves" which are the dependent objects. There are methods available to get/set the parent surface index and id, get/set the direction of the iso curve, and get/set the parameter which determines the location on the surface the curve matches.
All methods of this class are implemented by the system.

mpObject = NULL;
mpNSet = NULL;
mParentId = 0;
mParentIndex = -1;
mIsU = TRUE;

Member Function Documentation
| DllExport NURBSIsoCurve& operator= | ( | const NURBSIsoCurve & | curve | ) |
- Remarks:
- Assignment operator.
- Parameters:
- const NURBSIsoCurve&
curve
The curve to assign.
| DllExport void SetParent | ( | int | index | ) |
| DllExport void SetParentId | ( | NURBSId | id | ) |
- Remarks:
- Sets the NURBSId of the specified parent.
- Parameters:
- NURBSId id
The id to set.
| DllExport int GetParent | ( | void | ) |
- Remarks:
- Returns the index in the NURBSSet of the parent object.
| DllExport NURBSId GetParentId | ( | void | ) |
- Remarks:
- Returns the NURBSId of the parent. Note that a NURBSId won't be valid until the object has been instantiated in the scene.
| DllExport void SetDirection | ( | BOOL | isU | ) |
- Remarks:
- Sets the direction of the iso curve, either U or V.
- Parameters:
- BOOL isU
TRUE for U; FALSE for V.
| DllExport BOOL GetDirection | ( | void | ) |
- Remarks:
- Returns TRUE if the iso curve is in the U direction; FALSE for the V direction.
| DllExport void SetParam | ( | TimeValue | t, |
| double | p | ||
| ) |
- Remarks:
- Sets the parameter which determines where on the surface the iso curve is defined.
- Parameters:
- TimeValue t
The time at which to evaluate the surface.
double p
The parameter defining the location on the surface.
| DllExport double GetParam | ( | TimeValue | t | ) |
- Remarks:
- Returns the parameter which determines where on the surface the iso curve is defined.
- Parameters:
- TimeValue t
The time at which to evaluate the surface.
| DllExport BOOL GetTrim | ( | ) |
- Remarks:
- Returns the state of the trim flag. When set the surface is trimmed against the curve. When not set, the surface isn't trimmed
| DllExport void SetTrim | ( | BOOL | trim | ) |
- Remarks:
- Sets the state of the trim flag. When set the surface is trimmed against the curve. When not set, the surface isn't trimmed
- Parameters:
- BOOL trim
TRUE to trim; FALSE to not trim.
| DllExport BOOL GetFlipTrim | ( | ) |
- Remarks:
- Returns the state of the trim flip flag. When set this trims the surface in the opposite direction
| DllExport void SetFlipTrim | ( | BOOL | flip | ) |
- Remarks:
- Sets the state of the trim flip flag. When set this trims the surface in the opposite direction
- Parameters:
- BOOL flip
TRUE to flip; FALSE to not flip.
| DllExport Point2 GetSeed | ( | ) |
- Remarks:
- Returns the UV location of the seed value on the curve.
| DllExport void SetSeed | ( | Point2 & | seed | ) |
- Remarks:
- Sets the UV location of the seed value on the curve.
- Parameters:
- Point2&
seed
The seed value to set.
- Operators:
