OpenGL 3D Scene — Mini-Course Project

A 3D scene with procedurally generated spheres, real-time camera controls, and custom vertex/fragment shaders using OpenGL 3.3.

Overview

This project renders a 3D scene featuring multiple color-coded spheres with smooth shading, built entirely with modern OpenGL (core profile). The scene includes a free-look camera with mouse and keyboard controls, perspective projection, and per-vertex coloring through custom GLSL shaders.

Features

• Procedural sphere generation using parametric UV sphere tessellation
• Multiple objects with distinct colors and scales
• Free-look camera with WASD movement, mouse look, and scroll zoom
• Custom GLSL shaders — vertex shader for transformations, fragment shader for coloring
• Real-time rendering with delta-time-based movement

Controls

Input	Action
W / A / S / D	Move camera forward / left / back / right
Mouse	Look around
Scroll	Zoom in/out
ESC	Close window

Tech Stack

• C++ (OpenGL 3.3 Core Profile)
• GLFW — window management and input
• GLAD — OpenGL function loader
• GLM — mathematics (vectors, matrices, transformations)
• GLSL — vertex and fragment shaders

Building

Requires CMake and OpenGL development libraries:

cd OpenGL
mkdir build && cd build
cmake ..
make
./OpenGL
