Sky texturing
I`m trying to create new set of sky textures. As far as I know, they should be converted to polar coordinates. Maybe there are some values that I should know about?

you only needs to know how the coordinates are used:
_ the X coordinate of your texture corresponds to the angle around the Y axis (vertical axis), and the Y coordinate corresponds to the angle around the Z axis.
_ when computing the transformation to get UV coordinates for texture mapping we apply rotation around Z first then rotation around Y
_ mapping is done so that the top of the texture is the top of the sky and the bottom of the texture the bottom of the sky sphere.

Re: Sky texturing
Hehe, I`ve got a huge amount of perfect space sky textures
I`ll post a link here tomorrow. What soft are you using to transform them to polar coordinates?
