Hallo,
I have this small extract of code from a book I have. But I don't really understand what is going on here. Is t0 and t1 given values in this code, even though Quadratic does not return anything (its a bool)?
ThanksCode:// Solve quadratic equation for _t_ values float t0, t1; if (!Quadratic(A, B, C, &t0, &t1)) return false; // Compute intersection distance along ray if (t0 > ray.maxt || t1 < ray.mint) return false;
