Hello all,
Does anyone know a book about GLSL ES 1.0? Especially about Shaders, but for iOS not for Computers.
I searched on the net a book about shaders and iOS, but I didn’t find any book.
I know about GLSL ES Specification version 1.0.17 from here, but this is only a reference, not a tutorial.
What I am trying to say is that I’m not looking for a reference, I’m looking for a book with lessons.
Can someone help me?
Hi @Georgian , I would say a good place to start would be the built-in Codea Shaders.
Most of them are very straightforward !
http://ofps.oreilly.com/titles/9780596804824/ is online and covers shaders
Any iOS book about opengl es 2.0 will be ok, but I don’t know any that specifically cover shaders.
http://glsl.heroku.com is also great to learn and practice
Finally, the apple docs cover shaders fairly well with specs and best practice !
Hope this helps,
Cheers
There is a ‘write-up’ of the basic shader and the Blend Images shader on the wiki here. More write-ups may follow.
.@Georgian - I’ve done a basic intro here: http://codeatuts.blogspot.com.au/2012/11/tutorial-24-basic-3d-graphics.html
.@Andrew_Stacey’s has also done a (very detailed) tutorial on Using Matrices in Codea: http://loopspace.mathforge.org/discussion/13/matrices-in-codea
@Reefwing, I was busy with other things and I almost forgot about your website.
I visited your tutorial, but I think this tutorial should be continued, Part 2, Part 3, and so on.
.@Georgian - yep lots more to talk about regarding shaders. Unfortunately its not really an area of expertise for me so I have to learn it before I can explain it.
I’ve just recieved “OpenGL ES 2.0 Programming Guide” which has already helped me figure out something I was stuck on.
It’s not IOS specific, more a general coverage of GL ES 2.0 which heavily revolves around GLSL 1.0.
Seems good on the 5 minute skim 
This reference card is quite nice, the last pages list some of the available functionality in a shader.
