sogl

This is a WIP project

sogl (Simple OpenGL) is a light library for creating OpenGL applications in C++20.

It is best used as a subproject (using either git submodules or CMake FetchContent).

The goal of this library is to provide quick and simple tools for creating OpenGL applications.

Supported features

• Easily open a Window with an OpenGL context
• Window events (KeyPress/KeyRelease, MousePress/MouseRelease, MouseMove, Scroll, Resize, Drop)
• Textures from file
• Shaders (vertex and fragment)
• VertexArray (using vertex buffers and index buffers)

Get started

Just download sogl and add these lines to your CMakeLists

add_subdirectory(sogl)
target_link_libraries(YOUR_TARGET PUBLIC sogl::sogl)

sogl will automatically download and link its dependencies.

Here is a sample code to try out :

#include <iostream>
#include <sogl/sogl.hpp>

int main() {
    auto window = sogl::Window(960, 540, "sogl app");

    while (window.isOpen()) {
        while (auto event = window.nextEvent()) {
            if (auto press = event->as<sogl::Event::KeyPress>()) {
                if (press->key == sogl::Key::Escape) {
                    window.close();
                }
            }
            else if (auto mouse_press = event->as<sogl::Event::MousePress>()){
                if (mouse_press->button == sogl::MouseButton::Left) {
                    auto mouse_pos = window.getMousePosition();
                    std::cout << "Left click at (" << mouse_pos.x << ", " << mouse_pos.y << ")\n";
                }
            }
        }
        window.clear();
        window.display();
    }

    return 0;
}
