[SOLVED] Sun azimuth and elevation

[michal]

Hello, everyone, 
can you give me any advice on how to get a vector described by azimuth and elevation of the sun.

See the picture. Thank you for any help.

Hello! try something like this:

vec3 sun_dir = sun->getWorldDirection(AXIS_Z);
float azimuth = Math::atan2(sun_dir.x, sun_dir.y) * Math::Consts::RAD2DEG
float elevation = Math::acos(clamp(-sun_dir.z, -1.0f, 1.0f)) * Math::Consts::RAD2DEG - 90.0f
