Lore

Lore, Light OpenGL Rendering Engine, allows you to create/import 3D environment. You can create games, use it to visualize raw data, etc...

Exemple

A simple window that closes when ESCAPE key is pressed

#include <iostream>
#include <Lore.h>

using std::cout;
using std::endl;

using namespace LORE;

int main(int argc, char** argv) {
    cout << "===== INIT =====" << endl;

    LORE::Window* window = Lore::init(); // Initializes OpenGL context and creates a Window
    if(!window) {
        cout << "Error during OpenGL context initialization." << endl;
        Lore::unload();
        return -1;
    }

    //----------
    Camera* camera = new Camera();
    window->setCamera(camera);

    Controller* controller = new Controller(); // a Controller to bind the ESCAPE key to the Window
    controller->bind(GLFW_KEY_ESCAPE, [&window](double x, double y) {
        window->close();
    });

    //===================================
    cout << "===== RENDER =====" << endl;

    while (!window->shouldClose()) {
        int start = window->startFrame(); // Begin the frame render process
        controller->check(window); // Checks all bindings for the Window and execute de fonction if it matches
        window->render();
        window->endFrame(start); // End the frame render process and display the image on the window
    }

    //================================
    cout << "===== END =====" << endl;
    Lore::unload(); // Unload all dictionnaries, and unload OpenGL context
    return 0;
}

Why ?

The purpose of this project is to create a simple and lightweight tool to use all the OpenGL's power.
