Method GetNearestPoint

GetNearestPoint(BezierCurve, Ray, int)

Gets the point on a BezierCurve nearest to a ray.

Declaration

public static float3 GetNearestPoint(BezierCurve curve, Ray ray, int resolution = 16)

Parameters

Type	Name	Description
BezierCurve	curve	The BezierCurve to compare.
Ray	ray	The input ray.
int	resolution	The number of line segments on this curve that are rasterized when testing for the nearest point. A higher value is more accurate, but slower to calculate.

Returns

Type	Description
float3	Returns the nearest position on the curve to a ray.

GetNearestPoint(BezierCurve, Ray, out float3, out float, int)

Gets the point on a BezierCurve nearest to a ray.

Declaration

public static float GetNearestPoint(BezierCurve curve, Ray ray, out float3 position, out float interpolation, int resolution = 16)

Parameters

Type	Name	Description
BezierCurve	curve	The BezierCurve to compare.
Ray	ray	The input ray.
float3	position	The nearest position on the curve to a ray.
float	interpolation	The ratio from range 0 to 1 along the curve at which the nearest point is located.
int	resolution	The number of line segments that this curve will be rasterized to when testing for nearest point. A higher value will be more accurate, but slower to calculate.

Returns

Type	Description
float	The distance from ray to nearest point on a BezierCurve.
