How to create textures for glshader

[sushobhit]

hi egon ,

I would like to learn the shader and while going through the example provided with jpct-ae(hello shader) i came across 3 files one the real image , second normal (bluish version of the same image) and third (a greyish version). An you combine these 3 to make the shader.

?? So if i have a image , how can I get the bluish one and the greyish one so that the texture could be applied?

also what is the programming that goes in the other two glsl files plz hlp

I created these textures by using some command line tool as described here: http://www.jpct.net/forum2/index.php?topic=3941.0

About your second question: Any GLSL tutorial that covers OpenGL ES will give you more insight on this topic than i can possibly provide.
