Method GetCurveUpVector

GetCurveUpVector(int, float)

Return the up vector for a t ratio on the curve. Contrary to EvaluateUpVector<T>(T, float), this method is trying to used cached values when possible for better performance when accessing to these values regularly.

Declaration

float3 GetCurveUpVector(int index, float t)

Parameters

Type	Name	Description
int	index	The index of the curve for which the length needs to be retrieved.
float	t	A value between 0 and 1 representing the ratio along the curve.

Returns

Type	Description
float3	Returns the up vector at the t ratio of the curve of index 'index'.
