i tried many times to do ssao in worldspace i mean: save world position in texture then sample with some vectors but it has some artefacts like some kind of twisted umbrella, so i decided to follow ssao tutorials that store geometry position in viewspace, however i have no idea what kind of numbers i would expect there (like for ndc i get -1.0..1.0 nums)
since its opengl es i rather not depend on hardware floating point textures and have to implement my own data storage. So what numbers i can face here?
