Hij = K ·Rij ·K−1. Here Rij denotes a column-wise permutation of R, shuffling the columns i and j to be column 1 and 2. 1.1. Computing y4 from y1, y2 and y3 Let a be a known aspect ratio defined as w/h, where h is the height and w the width of the front wall in the physical world (we know these dimensions from the rental site). Then, given two corner points p1 and p2 of a wall, defined by the two intersections of rays y1, y2 and y1, y3, respectively, we can compute the corner point p3 defined by the intersection of rays y2 and y4. Knowing p3 we easily obtain the ray y4. We now show how to compute p3. ∗Denotes equal contribution
