boxLineCollision() [1/2]

bool boxLineCollision	(	const aabb3f &	box,
		v3f	box_rotation,
		v3f	start,
		v3f	dir,
		v3f *	collision_point,
		v3f *	collision_normal,

boxLineCollision() [2/2]

bool boxLineCollision	(	const aabb3f &	box,
		v3f	start,
		v3f	dir,
		v3f *	collision_point,
		v3f *	collision_normal )

Checks if a line and a box intersects.

Parameters

[in]	box	box to test collision
[in]	start	starting point of the line
[in]	dir	direction and length of the line
[out]	collision_point	first point of the collision
[out]	collision_normal	normal vector at the collision, points outwards of the surface. If start is in the box, zero vector.

Returns

true if a collision point was found
