WebFeb 27, 2024 · For each ray p=s+t d (in world space), transform the start position and direction of the ray into barycentric coordinates: b=M.s+t M.d. Finding the intersection with the triangle’s plane is just solving a+b+c=1 for t, i.e. u+t v=1 => t= (1-u)/v where u and v are just the sums of the coordinates of M.s and M.d respectively.
