OpenGL (SDL,C++) tutorial 17 - ray tracing (ray-plane intersection)

[jpknie]

Is it good practice to check if some floating point value is exactly zero? No, because of precision errors. You should use some epsilon (which is very small) value and do something like this:

std::abs(x - y) <= epsilon * std::abs(x);

The material you are showing is abundant on the web, but there aren't many good videos about the subject. So thanks for taking the time to post the videos. Keep up the good work
