Creating Float textures ?


Anyone has idea on what are “float textures” ?

Like on Opengl side, I’m generating a 1D texture using an array of floats as a data source…like as shown…and later I want to pass this 1D texture as “sampler1D” to my fragment program.


Now my worry is whether my gradient elements have been really treated as float elements in frag Program. I read somewhere that there is something called “float textures” ? Anyidea how these are created ? Any API on OpengL side to do that ?

Hi !

The best place to look for is the opengl spec. you can find it on this website.
