WebThe flags controlling the ray trace. An 8-bit “culling mask”. Each instance used to build a TLAS includes an 8-bit mask. The instance mask is binary-AND-ed with the given culling mask and the intersection skipped if the AND result is 0. WebIf we develop, we get (equation 1): P = A − u A − v A + u B + v C = A + u ( B − A) + v ( C − A) Note that (B-A) and (C-A) are the edges AB and AC of the triangle ABC. The intersection P can also be written using the ray's parametric equation (equation 2): P = O + t D. Where t is the distance from the ray's origin to the intersection P.
