◆ IsIdentity() [1/4]

Provides a quick way to determine if a morph function is the identity (doesn't move the points) on a region of space.
- Parameters
-
| bbox | [in] region of space to test. |
- Returns
- The default always returns false. If you override this function, then return true when every point in the bounding box is fixed by the morph.
Reimplemented in ON_CageMorph.
◆ IsIdentity() [2/4]
A slower way to determine if a morph function is the identity (doesn't move the points) on a set of points, to within a tolerance
- Parameters
-
| Points | [in] Set of points to test. |
| tol | [in] Distance tolerance. |
- Returns
- True if none of the points move a distance of tol or more under the morph function. Uses MorphPoint()

| const |
A slower way to determine if a morph function is the identity (doesn't move the points) on a surface, to within a tolerance
- Parameters
-
| Srf | [in] Surface to be tested. |
| tol | [in] Distance tolerance. |
- Returns
- Uses MorphPoint() on a dense sample of points. True if none of the points move a distance of tol or more under the morph function. Remark: Call IsIdentity(Srf.BoundingBox()) first. Use this on surfaces whose nurb form is rational or has a different parameterization.
◆ IsIdentity() [4/4]
| bool ON_SpaceMorph::IsIdentity |
( |
const class ON_Curve & |
Crv, |
|
|
double |
tol |
|
) |
| const |
A slower way to determine if a morph function is the identity (doesn't move the points) on a curve, to within a tolerance.
- Parameters
-
| Crv | [in] Curve to be tested. |
| tol | [in] Distance tolerance. |
- Returns
- Uses MorphPoint() on a dense sample of points. True if none of the points move a distance of tol or more under the morph function. Remark: Call IsIdentity(Crv.BoundingBox()) first. Use this on curves whose nurb form is rational or has a different parameterization.
◆ PreserveStructure()
| bool ON_SpaceMorph::PreserveStructure |
( |
| ) |
const |
- Returns
- True if the morph should be done in a way that preserves the structure of the geometry. In particular, for NURBS objects, true means that only the control points are moved.
The value returned by PreserveStructure() does not affect the way meshes and points are morphed. The default is false.
◆ QuickPreview()
| bool ON_SpaceMorph::QuickPreview |
( |
| ) |
const |
- Returns
- True if the morph should be done as quickly as possible because the result is being used for some type of dynamic preview. If QuickPreview is true, the tolerance may be ignored.
The value returned by QuickPreview() does not affect the way meshes and points are morphed. The default is false.
◆ SetPreserveStructure()
| void ON_SpaceMorph::SetPreserveStructure |
( |
bool |
bPreserveStructure | ) |
|
Set the preserve structure value.
- Parameters
-
◆ SetQuickPreview()
| void ON_SpaceMorph::SetQuickPreview |
( |
bool |
bQuickPreview | ) |
|
Set the quick preview value.
- Parameters
-
◆ SetTolerance()
| void ON_SpaceMorph::SetTolerance |
( |
double |
tolerance | ) |
|
Set the 3d fitting tolerance used when morphing surfaces and breps.
- Parameters
-
| tolerance | [in] values < 0.0 are treated as 0.0. |
◆ Tolerance()
| double ON_SpaceMorph::Tolerance |
( |
| ) |
const |
Returns the desired accuracy of the morph. This value is primarily used for deforming surfaces and breps.
- Returns
- 3d fitting tolerance.
The default is 0.0 and any value <= 0.0 is ignored by morphing functions. The value returned by Tolerance() does not affect the way meshes and points are morphed.
