Any good fast algorithm or link for intersection of two AABBs (Axis Aligned Bounding Boxes)? Thanks in advance

You just want to know if they intersect? You can find that info just about anywhere, but...

You only need to do six tests:

if (box1.max.x < box2.min.x)
// they don''t intersect
if (box2.max.x < box1.min.x)
// they don''t intersect

And likewise for y and z.
