public abstract class Curve : ICurve, ITransformable<Curve>Methods
ParameterAtDistanceFromParameter(Double, Double)
Get the parameter at a distance from the start parameter along the curve.
Declaration
public abstract double ParameterAtDistanceFromParameter(double distance, double start)Parameters
| Type | Name | Description |
|---|---|---|
| System.Double | distance | The distance from the start parameter. |
| System.Double | start | The parameter from which to measure the distance. |
Returns
| Type | Description |
|---|---|
| System.Double |
PointAt(Double)
Get a point along the curve at parameter u.
Declaration
public abstract Vector3 PointAt(double u)Parameters
| Type | Name | Description |
|---|---|---|
| System.Double | u | A parameter along the curve between domain.min and domain.max. |
Returns
| Type | Description |
|---|---|
| Vector3 | A point along the curve at parameter u. |
TransformAt(Double)
Get a transform whose XY plane is perpendicular to the curve, and whose positive Z axis points along the curve.
Declaration
public abstract Transform TransformAt(double u)Parameters
| Type | Name | Description |
|---|---|---|
| System.Double | u | The transform at a parameter along the curve between domain.min and domain.max. |
Returns
| Type | Description |
|---|---|
| Transform | A transform on the curve at parameter u. |
Transformed(Transform)
Create a transformed copy of this curve. Use of non-affine transforms (i.e. scale) will result in unpredictable results for curve methods such as Length().
Declaration
public abstract Curve Transformed(Transform transform)Parameters
| Type | Name | Description |
|---|---|---|
| Transform | transform | The transform to apply. |
Returns
| Type | Description |
|---|---|
| Curve |
