3D model done with OpenGL

This project was developed as part of the Computer Graphics course at Alexandria University. It demonstrates the creation of a simple 3D graphics model using OpenGL. The project renders multiple pyramids with textures and allows basic transformations, such as translation and rotation.

Project Structure

• Main.cpp: The main entry point of the application, containing the window setup, main rendering loop, and input handling.
• Camera.cpp / Camera.h: Handles camera setup, movement, and view transformations.
• EBO.cpp / EBO.h: Element Buffer Object (EBO) management for handling indexed drawing.
• Texture.cpp / Texture.h: Texture loading and management using stb_image.
• VAO.cpp / VAO.h: Vertex Array Object (VAO) management for storing vertex attributes.
• VBO.cpp / VBO.h: Vertex Buffer Object (VBO) management for storing vertex data.
• shaderClass.cpp / shaderClass.h: Shader management for compiling, linking, and using vertex and fragment shaders.
• default.vert: Vertex shader for processing vertex attributes.
• default.frag: Fragment shader for handling pixel color outputs.
• Libraries: Contains third-party libraries such as GLAD, GLFW, stb_image, and GLM.
• Resources: Additional files like textures (brick.png, ground_texture.png) and shaders.

Main Features

• Rendering 3D Objects: Renders multiple textured pyramids in a 3D space.
• Transformations: Supports rotation and translation transformations on the 3D objects.
• Texture Mapping: Applies texture to 3D objects using texture coordinates and fragment shaders.
• Camera Controls: Uses a camera class to manage view transformations.
• Depth Buffering: Enabled for correct rendering order of overlapping objects.

Requirements

• C++ Compiler: GCC, Clang, or MSVC that supports C++11 or later.
• Libraries:
  • GLFW - for window management and input handling.
  • GLAD - for loading OpenGL extensions.
  • GLM - for mathematics operations.
  • stb_image - for image loading.

Running the Project

To run the project, you will need to compile it using a C++ compiler that supports C++11 or higher, along with OpenGL, GLFW, GLAD, and other dependencies.

# Example command to compile using g++ (ensure you have OpenGL and GLFW installed)
g++ -o GameEngine Main.cpp Camera.cpp EBO.cpp Texture.cpp VAO.cpp VBO.cpp shaderClass.cpp glad.c -lglfw -lGL -ldl
./GameEngine

Rendering Output

The application renders a 3D scene with multiple pyramids that rotate around their y-axis. Below is a screenshot of the rendered scene:
