Function Documentation

RaySphere() [1/2]

JPH_NAMESPACE_BEGIN JPH_INLINE float RaySphere	(	Vec3Arg	inRayOrigin,
		Vec3Arg	inRayDirection,
		Vec3Arg	inSphereCenter,
		float	inSphereRadius
	)

Tests a ray starting at inRayOrigin and extending infinitely in inRayDirection against a sphere,

Returns

FLT_MAX if there is no intersection, otherwise the fraction along the ray.

Parameters

inRayOrigin	Ray origin. If the ray starts inside the sphere, the returned fraction will be 0.
inRayDirection	Ray direction. Does not need to be normalized.
inSphereCenter	Position of the center of the sphere
inSphereRadius	Radius of the sphere

RaySphere() [2/2]

JPH_INLINE int RaySphere	(	Vec3Arg	inRayOrigin,
		Vec3Arg	inRayDirection,
		Vec3Arg	inSphereCenter,
		float	inSphereRadius,
		float &	outMinFraction,
		float &	outMaxFraction
	)

Tests a ray starting at inRayOrigin and extending infinitely in inRayDirection against a sphere. Outputs entry and exit points (outMinFraction and outMaxFraction) along the ray (which could be negative if the hit point is before the start of the ray).

Parameters

inRayOrigin	Ray origin. If the ray starts inside the sphere, the returned fraction will be 0.
inRayDirection	Ray direction. Does not need to be normalized.
inSphereCenter	Position of the center of the sphere.
inSphereRadius	Radius of the sphere.
outMinFraction	Returned lowest intersection fraction
outMaxFraction	Returned highest intersection fraction

Returns

The amount of intersections with the sphere. If 1 intersection is returned outMinFraction will be equal to outMaxFraction
