Texture formats

hi all,

it simply doesn’t get into my mind, why i.e. gregsn’s waveshader doesn’t work with 32bit floating point textures like R32F, G32R32F… maybe i haven’t understood some basic things concerning sampling different texture formats in shaders… please could anybody make this clear to me?

thx for any hints!

ok, now i got it working…no clue why the simulation always blew up the first few times when i changed the texture format…
