Hello everybody,
I try to make a code find an intersection between a ray and a box. I read a
lot of thing on the internet and one of the best code I could find is this
one.
def box_aabb_intersect(bbox_min, bbox_max, ray, direction):
t1 = (bbox_min.x - ray.x) * direction.x
t2 = (bbox_max.x - ray.x) * direction.x
t3 = (bbox_min.y - ray.y) * direction.y
t4 = (bbox_max.y - ray.y) * direction.y
t5 = (bbox_min.z - ray.z) * direction.z
t6 = (bbox_max.z - ray.z) * 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 t_max < 0.0 or t_min > t_max:
return
return t_min
Everyone says it works but I can not make it work at home. Does someone
have an idea?
