IDBitMask Tut7

.

I speak VB and don't speak C, so i'm a bit fuzzy on IDBitMask.

i understand it's a bitwise comparison, but what i'm fuzzy on is:

Suppose you set IDBitMask to x and you cast a ray from pointA->pointB

on the way through A->B the ray first hits a surface with IDBitMask y then past that (if it kept going) that it would hit IDBitMask x

Because the IDBitMask for the ray collision was set to x then does it pass through the y surface and return the location of the x surface collision? or does it stop at y and say it hit nothing because IDBitMask was set for x and not the impacted y?

(sorry if i sound vague)

Depends on x and y. But if those are disjunct bitmasks you would get a result on the x node, because nodes which are not using the current mask are kind of invisible

Do i understand this correctly then?
