Function to create AO from Normal map?

RashedAlmetrami

Hey guys, was wondering whether it's possible to create a function which converts a normal map into an ambient occlusion map?

If so, how would I go about doing something like this?

Cheers!

Height would be a better source, and no, there isn't such a function by default, but you could definitely make one.

Thanks for the reply! Anywhere you can guide me to look over the math involved?

Any realtime ambient occlusion implementation paper.
