Math::HitResult

struct Math::HitResult

Represents the result of a ray-object intersection test.

Contains information about which object was hit by a ray and the distance from the ray origin to the intersection point.

Definition at line 146 of file MathUtils.h.

Data Fields
float	distance	Distance from the ray origin to the intersection point. Infinity if no hit.
IPickable *	object	Pointer to the hit object, or nullptr if no intersection.
