Yea I want to use it because it is the latest. I've updated my drivers few months ago and checked just now if I am up to date and I am.

If OpenGL is not fully supported by today's graphics card then what version should I use because I've read that for example glBegin(...) ... glEnd() is slower than using those 1 call functions with supplying the array as parameter.

General / OpenGL 4.2

« on: July 31, 2012, 12:50:50 pm »

Hello all,

What should I do for my program(game) to use OpenGL 4.2? I've been searching on google for some time now and I can't figure it out. I am trying to follow these tutorials: http://www.opengl-tutorial.org/ but instead of using GLFW I am going to use SFML because I am more familiar with it and it seems easier and more powerful. I found some info about gl3.h file so I included it but I get linker errors about some missing .lib file which I cannot find at all. If anyone has got any information what so ever then please reply with something because I don't want to use deprecated OpenGL 1.1 functions.

@Edit: I also tried using glew because I read that I can use newest OpenGL with it but it crashes if using non-1.1-version functions when launching the application with it.

Dude, if a variable is created within the loop (in the brackets) after the next iteration, it is destroyed.

Do:

{ int Variable = 5; }
std::cout << Variable;

Will give you error because Variable will not exist.

Maybe this helps

#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderWindow window(sf::VideoMode(800, 600), "Hidden Cursor");
    window.setMouseCursorVisible(false); // Hide cursor
   
    sf::View fixed = window.getView(); // Create a fixed view
   
    // Load image and create sprite
    sf::Texture texture;
    texture.loadFromFile("cursor.png");
    sf::Sprite sprite(texture);
   
    while(window.isOpen())
    {
        sf::Event event;
        while(window.pollEvent(event))
        {
            if(event.type == sf::Event::Closed)
            {
                window.close();
            }
        }
       
        sprite.setPosition(static_cast<sf::Vector2f>(sf::Mouse::getPosition(window))); // Set position
       
        window.clear();
        window.setView(fixed);
        window.draw(sprite);
        window.display();
    }

    return EXIT_SUCCESS;
}

As the title says, will there ever be such an extension for this library and is there something like free SDK for PS3 for students who want to experiment?

Ok thanks mate the title is now normal, but I still get the black window. In short, I think glTranslatef doesn't work properly.

But i think its for 1.6.

@down: nvm dude I thought the link u gave me was for 1.6 version.

It's not a feature but it would be useful if Source Code for examples in SFML 2.0 package would be available. I searched every folder and all I could find was the .exe files.

It's basically the same as here: http://www.sfml-dev.org/tutorials/2.0/window-opengl.php + shape drawing code from here: http://nehe.gamedev.net/tutorial/your_first_polygon/13002/


Also in the Window title some strange symbols appear before "OpenGL" text

General / Problem with OpenGL

« on: July 23, 2012, 06:08:33 pm »

Hi all,

For a long time I've been trying to write myself a little game with no success. I finally found this library and I've downloaded 1.6 version, everything was great but my program was crashing with some App stack error when closing so I've downloaded 2.0 and I run into some problems. I used the tutorial on OpenGL for 2.0 and I put code for drawing a triangle and a square from NeHe tutorials but I get a black screen, when I comment glTranslatef the shapes show up one on top of the other so I googled glTranslatef not working and I found this topic http://www.opengl.org/discussion_boards/showthread.php/129644-glTranslatef-not-working except I am not using glut. Any ideas how can I fix this?
