"WebThe arguments are interpreted as follows: origin is the start point of the ray.; unitDir is a unit vector defining the direction of the ray.; maxDist is the maximum distance to search along the ray. It must be in the [0, inf) range. If the maximum distance is 0, a hit will only be returned if the ray starts inside a shape, as detailed below for each geometry. " - Ray-aabb intersection normal

Since the AABB is axis-aligned, we know the three axes will always be (1, 0, 0), (0, 1, 0) and (0, 0, 1). So, as an optimization, I hardcoded the results of the cross-products. Check the intersection with those 9 axes, the 3 AABB face normals and the triangle face normal.
