[SOLVED] Sun position (rotation) from direction vector

[arzezniczak]

Hi,
I've got direction vector that describes sun position in my app. I'm trying to use this vector to set proper sun rotation in Unigine (LightWorld::setWorldRotation). Is there any example how can I do this? Could you help me a little bit?
I've tried to use Unigine::Math::lookAt but no luck - it doesn't work as I would expect.

Problem solved, provided links were very helpful.
I've been able to calculate azimuth and elevation from my direction vector, then I'm using it to build rotation quaternion.

Thank you!
