General / need tutorial for terrian making. [openGL]

« on: June 28, 2017, 06:17:29 am »

Hi everybody. Im the noobest of noobest in this forum. Im trying to get a 3D heightmap done using SFML and OpenGL. For past week or so I tried this retro Glut source code port into SFML but it only did work as 2D in sfml render window 

Any SFML based terrian tutorials are there ? Just simple source code to get started with.

thanks

General / Glut render to SFML render

« on: June 27, 2017, 12:55:56 pm »

First of all, Im a super noob to SFML
Im trying to get this heightmap loaded into my SFML project. Its currenly running with glut opengl window. But I could not figure out how to get it into SFML render.

here is my main function


int main()
{
   sf::RenderWindow window(sf::VideoMode(600, 600), "OpenGL SFML", GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH);
   window.setFramerateLimit(60);
   window.setVerticalSyncEnabled(true);

   _terrain = loadTerrain("heightmap.bmp", 15);

   sf::Clock Clock;

   window.setActive(true);
   bool running = true;

   while (running)
   {
      sf::Event event;
      while (window.pollEvent(event))
      {
         if (event.type == sf::Event::Closed)
         {
            window.close();
         }
         if ((event.type == sf::Event::KeyPressed) && (event.key.code == sf::Keyboard::Escape))
         {
            window.close();
         }
         else if (event.type == sf::Event::Resized)
         {
            // adjust the viewport when the window is resized
            glViewport(0, 0, event.size.width, event.size.height);
         }
      }

      glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

      //window.pushGLStates();
      window.draw(drawScene);

      //drawScene();
      //Terrain.drawScene();

      //window.clear(sf::Color::Black);

      /*glutDisplayFunc(drawScene);
      glutKeyboardFunc(handleKeypress);
      glutReshapeFunc(handleResize);
      glutTimerFunc(25, update, 0);*/

      window.display();

   }

I get errors
