OpengGL Shader Program fails
-
Those are remnants from my previous trials.I don't think those influence the modern pipeline as I am using a compatibility mode .So those should be discarded by the OpenGL. Regarding the matrices ,you can see that I load a orthogonal projection matrix into the vertex shader on each render loop. Still nothing works.If anybody could put a full example on how to write a OpenGL 3x in Qt it could be really helpful to many people I believe :)

Hey, I have example, http://minimoog.wordpress.com/2010/05/10/transfverteksi/ Oh, I am sorry it's in my native language (if it is for somebody interesting I would translate/write in english) but code is simple for understanding http://dl.dropbox.com/u/6108964/QtGL2.zip
BR.

Also you can use it for learning basic usage of VBO. :)

[quote author="sasmaster" date="1316340394"]I can see you didn't define the format and it actually works ?Another question ,are those inclosed GLEW headers and sources used in your program? [/quote]
By format you mean 'window framebuffer pixel format'?
Yes, it's using GLEW, since there are glGenBuffers, glBindBuffers, glBufferData, glVertexAttribPointer etc.

[quote author="sasmaster" date="1316343899"]But why haven't you used the Qt version of those methods?[/quote]
You mean QGLBuffer. Well at that time there was no QGLBuffer.
[quote]By Format I mean the QGLFormat.[/quote]
It uses default format. I don't see why would I need a fancy format for that code. :)

An idea (maybe wrong...) : Implementation of openGL is platform (hardware) dependent. So I guess it could permit an universal call through various platforms or OpenGL revision (and avoid use of OGL extension which I used to add on mac OS platform for exemple).
Nervertheless I prefer use pure OpenGL functions call as long as OGL 4.0 (and so OGL ES 2.0) will not be supported anywhere...
