Thank you for your answer Alok,
After much rereading and viewing other script on the internet I saw my
error ... you have to replace the * by / for each "edge" ...
I have only one condition that tells me whether I have an intersection or
not. In this case I return None. The script that will call this function
will have to make the verification namely: If it's none I do what? This is
not None so I have the min, max values of my intersection
def box_aabb_intersect(self, m_bbox):
"""
!@Brief Check if ray intersect boundingBox.
@type m_bbox: OpenMaya.MBoundingBox
@param m_bbox: BoundingBox you want to check
@rtype: float
@return: Distance of ray origin and intersect point.
"""
t1 = (m_bbox.min().x - self.__v_origin.x) / self.__v_direction.x
t2 = (m_bbox.max().x - self.__v_origin.x) / self.__v_direction.x
t3 = (m_bbox.min().y - self.__v_origin.y) / self.__v_direction.y
t4 = (m_bbox.max().y - self.__v_origin.y) / self.__v_direction.y
t5 = (m_bbox.min().z - self.__v_origin.z) / self.__v_direction.z
t6 = (m_bbox.max().z - self.__v_origin.z) / self.__v_direction.z
t_min = max(max(min(t1, t2), min(t3, t4)), min(t5, t6))
t_max = min(min(max(t1, t2), max(t3, t4)), max(t5, t6))
# if tmax < 0, ray (line) is intersecting AABB, but the whole
AABB is behind us
# if tmin > tmax, ray doesn't intersect AABB
if t_max < 0.0 or t_min > t_max:
return
return t_min, t_max
