这个基于OpenGL的3D渲染项目专注于实现多种光源、多种材质处理以及天空盒效果的展示。它利用了GLFW、GLAD和GLM库来创建窗口、处理用户输入和进行数学运算。项目的核心在于使用OpenGL渲染技术，展示不同类型的光源（如定向光、点光源和聚光灯）和材质效果（如漫反射和镜面高光贴图）。此外，通过实现天空盒功能，项目增强了3D场景的深度和沉浸感。用户可以通过键盘和鼠标控制相机，观察由多种光源照亮的具有不同材质的物体，以及周围的天空盒环境。
This OpenGL-based 3D rendering project focuses on showcasing multiple light sources, various material handling, and skybox effects. Utilizing libraries such as GLFW, GLAD, and GLM, it creates windows, processes user inputs, and performs mathematical operations. The project's essence lies in employing OpenGL rendering techniques to display different types of light sources (like directional lights, point lights, and spotlights) and material effects (such as diffuse and specular mapping). Additionally, by implementing the skybox feature, the project enhances the depth and immersion of the 3D scene. Users can control the camera using the keyboard and mouse, observing objects with different materials illuminated by various light sources, surrounded by a skybox environment.

To enhance the portability of the project and ensure that downloaders can run it seamlessly, we've made the following modifications to the project settings.
Users don't need to perform these actions; this is provided for informational purposes.
We've added the following paths to the project's include directories:
$(ProjectDir)include$(IncludePath)
This ensures that the project can locate necessary header files and dependencies without manual configuration.
We've included the following paths in the project's library directories:
$(ProjectDir)lib$(LibraryPath)
By doing so, we make sure that the project can find required libraries and link them correctly during compilation.
These modifications have been made to simplify the setup process for users and promote the project's portability.
