Method EvaluatePositionTangentNormal

EvaluatePositionTangentNormal<T>(T, NativeArray<float3>, NativeArray<float3>, NativeArray<float3>)

Populate a set of pre-allocated NativeArray with position, tangent, and normal data from a spline.

Declaration

public static void EvaluatePositionTangentNormal<T>(T spline, NativeArray<float3> positions, NativeArray<float3> tangents, NativeArray<float3> normals) where T : ISpline

Parameters

Type	Name	Description
T	spline	The spline to evaluate. If you pass a NativeSpline, it must be allocated with the Persistent or TempJob allocator. Temp is invalid for use with the Jobs system.
NativeArray<float3>	positions	A preallocated array of float3 to be populated with evenly interpolated positions from a spline.
NativeArray<float3>	tangents	A preallocated array of float3 to be populated with evenly interpolated tangents from a spline. Must be the same size as the positions array.
NativeArray<float3>	normals	A preallocated array of float3 to be populated with evenly interpolated normals from a spline. Must be the same size as the positions array.

Type Parameters

Name	Description
T	The type of ISpline.

Remarks

To apply a transform to the results of this method, pass a new NativeSpline constructed with the desired transformation matrix.

This method creates a temporary NativeSpline copy of the spline to be evaluated. In some cases, this can be more resource intensive than iterating and evaluating a spline on a single thread. For the best performance, pass an existing NativeSpline instance to the spline parameter.

EvaluatePositionTangentNormal(NativeSpline, NativeArray<float3>, NativeArray<float3>, NativeArray<float3>)

Populate a set of preallocated NativeArray with position, tangent, and normal data from a spline.

Declaration

public static void EvaluatePositionTangentNormal(NativeSpline spline, NativeArray<float3> positions, NativeArray<float3> tangents, NativeArray<float3> normals)

Parameters

Type	Name	Description
NativeSpline	spline	The spline to evaluate. The NativeSpline must be allocated with a Persistent or TempJob allocator. Temp is invalid for use in the Jobs system.
NativeArray<float3>	positions	A preallocated array of float3 to be populated with evenly interpolated positions from a spline.
NativeArray<float3>	tangents	A preallocated array of float3 to be populated with evenly interpolated tangents from a spline. Must be the same size as the positions array.
NativeArray<float3>	normals	A preallocated array of float3 to be populated with evenly interpolated normals from a spline. Must be the same size as the positions array.

Remarks

To apply a transform to the results of this method, pass a new NativeSpline constructed with the desired transformation matrix.
