OGLplus OpenGL的C++封装库

OGLplus (oglplus) 是一个仅包含头文件的 C++ 语言库，用于实现一个瘦面向对象的 OpenGL 门面操作接口，提供了自动资源和对象管理的封装，让在 C++ 中使用 OpenGL 更加简单和安全。

示例代码：

#include <oalplus/al.hpp>
#include <oalplus/all.hpp>
#include <oalplus/alut.hpp>

#include <chrono>
#include <thread>

int main(int argc, char** argv)
{
    // open the default device
    oalplus::Device device;
    // create a context using the device and make it current
    oalplus::CurrentContext context(device);
    // create an instance of ALUT
    oalplus::ALUtilityToolkit alut(false, argc, argv);
    // create a listener and set its position, velocity and orientation
    oalplus::Listener listener;
    listener.Position(0.0f, 0.0f, 0.0f);
    listener.Velocity(0.0f, 0.0f, 0.0f);
    listener.Orientation(0.0f, 0.0f,-1.0f, 0.0f, 1.0f, 0.0f);
    // create a Hello World sound and store it into a buffer
    oalplus::Buffer buffer = alut.CreateBufferHelloWorld();
    // create a source from the data in buffer and set its position
    oalplus::Source source;
    source.Buffer(buffer);
    source.Position(0.0f, 0.0f,-1.0f);
    // let the source play the sound
    source.Play();
    // wait for a while
    std::chrono::seconds duration(2);
    std::this_thread::sleep_for(duration);
    //
    return 0;
