Value returning 1.#INF000

Question

An intersection algorithm isn\'t working; one of the values, tmin, evaluates to 1.#INF000 - what does this mean and why is it occurring? tmax

Answer 1

1.#INF000 is most likely the positive infinity. If you are getting this, it means one of the following in case of your code:

• t1 and t2 are both infinite
• t3 and t4 are both infinite
• t5 and t6 are both infinite

My guess is that you are probably dividing by zero somewhere, most likely when you calculate the value of dirfrac.
