WebMar 24, 2016 · This way we obtain a transformed ray which we can intersect with an AABB. Once an intersection point is found, we need to transform this back to world space via the inverse transformation (i.e. local-to-world transformation). In practice an nAABB is thus expressed as an AABB with a pair of world-to-local and local-to-world transformation … WebConsider the OBB below. On the X axis, this is delimited by 2 vertical planes, colored in red here. When intersected with the ray (a very simple operation), it gives 2 intersections, one …

Webhit.pos is the point of contact between the two objects (or an estimation of it, in some sweep tests).; hit.normal is the surface normal at the point of contact.; hit.delta is the overlap between the two objects, and is a vector that can be added to the colliding object’s position to move it back to a non-colliding state.
