Fragment/Vertex Shaders! please look !

[pav]

hi, i just wanted to know...how exactly do u know how to use the vertex and fragment shaders? (guys like Humus,NitroGL and the rest..)
where and how exactly did u learn to use it???
it can't be just the specifications can it?
pls guide me! i'm dying to learn to use them!

The specification is quite good as a reference, but for the basics you're better of reading technical documents about them.

Look here for instance:

If you want to get your feet wet... download a program called 'Shader Studio' at http://www.shaderstudio.com . It is a very nice shader programming tool. It lets you load your own models.. apply textures, and apply vertex/pixel shaders interactively. And it actually seems very stable so far!

As Humus said, the specs are usally good enough of a learning reference.

A good understanding of math helps a lot too (though I'm not very good at it ).

And sample code is always good
