Function Documentation

RayCylinder() [1/2]

JPH_INLINE float RayCylinder	(	Vec3Arg	inRayOrigin,
		Vec3Arg	inRayDirection,
		float	inCylinderHalfHeight,
		float	inCylinderRadius )

Test a ray against a cylinder centered around the origin with its axis along the Y axis and half height specified.

Returns

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

Parameters

inRayDirection	Ray direction. Does not need to be normalized.
inRayOrigin	Origin of the ray. If the ray starts inside the cylinder, the returned fraction will be 0.
inCylinderRadius	Radius of the cylinder
inCylinderHalfHeight	Distance from the origin to the top (or bottom) of the cylinder

RayCylinder() [2/2]

JPH_NAMESPACE_BEGIN JPH_INLINE float RayCylinder	(	Vec3Arg	inRayOrigin,
		Vec3Arg	inRayDirection,
		float	inCylinderRadius )

Tests a ray starting at inRayOrigin and extending infinitely in inRayDirection against an infinite cylinder centered along the Y axis

Returns

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

Parameters

inRayDirection	Direction of the ray. Does not need to be normalized.
inRayOrigin	Origin of the ray. If the ray starts inside the cylinder, the returned fraction will be 0.
inCylinderRadius	Radius of the infinite cylinder
