    glViewport(0, 0, w, h);
    glMatrixMode(GL_PROJECTION);
    glLoadIdentity();

    Maybe you could try define GLEW_STATIC in the other file too, like you did in main.cpp . Honestly I'm not sure that's going to solve it, but you can give it a try :)

    Have you found your solution yet ? I use CodeBlocks too and when it crashes it removes all the linked libraries from projects, so on next run I have to link them again. I'm not sure if that applies...

    Thank you both for answers, your suggestion worked GClements.

    Carmine, the scaling idea sounds good but I wonder, will there be no loss of quality and accuracy on image for using such small units...

    MtRoad, now it works properly, thank you very much for your effort. And I should've paid closer attention to the "ribbon" vertices as well before just copying your code :) It is maybe a little...
  10. MtRoad - thank you for your explanations and...

    MtRoad - thank you for your explanations and code. I have tried your code and I still get the "ribbon". Also now it's back to the problem I had in the beginning, where whole image consisted only of...

    Carsten Neumann - yes , I was searching the internet and found out that I should pay attention to clearing depth buffer. And about what you said earlier, that I should read a text on transformation...

    Thank you. I have managed to make the texture appear on the background properly. Now I would like to render a blue square on it ( just for demonstration to learn how to draw on the background ). I...

    Thank you for reply. Some more questions follow up, since I didn't manage to make it work :/
    Where should I put an orthographic projection matrix instead of the perspective one ? There is only one...
  14. Loading a bitmap image to use it as a texture / background on canvas for drawing

    Greetings all !

    I intended to write some code that would load a bitmap image of Earth surface ( of size 1024x512 ) into a texture, and that texture would be displayed in a 1024x512 size FreeGLUT...

    Alexandar, I think I found the Red Book most suitable for me to start with as well. And I can see it has a very long tradition, close to my lifetime =) Do you ( or anyone ) have any idea where to get...

    Carmine, your project looks awesome. Close ( well, much better ) to what I expect to achieve some time. Is there a website with more information about your project available ? Also thank you for the...

    Fiodis - yes that was the tutorial I was mentioning. And what you said was exactly what was missing in my code, thank you. If you are familiar with OpenGL literature, I would kindly like to ask you...
  20. Thank you fiodis. I have already tried with SOIL...

    Thank you fiodis. I have already tried with SOIL ( I chose it over DevIL because I don't need such big library with so many supported formats ). But I get a flawed texture rendering. I tried it on a...

    Alexandar thank you for your comments. I think this settles it, for now I will go with legacy OpenGL, and leave the modern one when I will complete these projects and have the luxury of more time....

    You see, that is why I am confused. You both gave me great answers ( thanks for that ! ), but different ones. And it is same when I do research on 'old' vs 'new' OpenGL on my own - I can't figure out...
