General / SFML View and OpenGL
« on: January 05, 2018, 10:31:12 pm »
I have code:
#include <SFML/Graphics.hpp>
#include <SFML/OpenGL.hpp>
#include <GL/glut.h>
int main()
{
        sf::ContextSettings contextSettings;
        contextSettings.depthBits = 24;
        contextSettings.sRgbCapable = false;

        sf::RenderWindow window(sf::VideoMode(800, 600), "SFML graphics with OpenGL", sf::Style::Default, contextSettings);
        window.setVerticalSyncEnabled(true);

        sf::View view(sf::Vector2f(0, 0), sf::Vector2f(400, 300));

        sf::Texture texture;
        if (!texture.loadFromFile("texture.jpg"))
                return EXIT_FAILURE;

        glEnable(GL_DEPTH_TEST);
        glDepthMask(GL_TRUE);
        glClearDepth(1.f);

        glViewport(0, 0, window.getSize().x,window.getSize().y);

        glMatrixMode(GL_PROJECTION);
        glLoadIdentity();
        glLoadMatrixf(view.getTransform().getMatrix());

        sf::RectangleShape shape(sf::Vector2f(100, 100));

        static const GLfloat cube[] =

                window.popGLStates();

                window.display();
        }

        return EXIT_SUCCESS;
}
 
and have problem because i want to move view and Opengl stuff move too.
I know that there is a problem
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glLoadMatrixf(view.getTransform().getMatrix());

After add this line:
glLoadMatrixf(view.getTransform().getMatrix());
object OpenGL just fade away.

Can u tell me how exactly i can do this ? 3D effect will be still visible ?
Thanks
PS. sorry for my english ;)
