WebJul 21, 2024 · This is exactly what we do during a Ray-AABB intersection. Therefore, let’s start the algorithm off by computing the parametric distance of the ray to the four axis … WebFeb 3, 2024 · We can reach the plane (means intersect at point p) using the parametric form: l0 + l * t = p (ii) If the ray isn’t parallel to the plane, then t times in the direction of the ray; the ray will interest the plane. Next, we can put the value of p from equation (ii) into the equation (i), and we get: (l0 + l * t – p0) . n = 0. ipreo new issue
