Hi,

I did, but it seems to me, that this is only offline transform - exact same thing that proj does. I want to transform points "on the fly". Can I somehow use Helmert transformation (from +towgs84 proj param) ? I dont need to transform between multiple systems, just to wgs84 would be nice and I dont need grids to do precise transform.

If I cant do matrix transformation, can proj transformation be done in shader: not implementing matrix transform but rather "full proj" transform ?

Thank you!

Cheers,
Filip
