# Interactive OpenGL Environment

## Overview

The goal of this project is to create an interactive OpenGL environment where users can navigate through a virtual scene, viewing objects from any desired angle, and manipulating various parameters such as fog and light angles.

## Features

- **Interactive Navigation**: Users can navigate the scene using keyboard controls (WASD, arrow keys) and mouse input to move the camera in 3D space and change its orientation.

- **Lighting Control**: Ambient light direction can be adjusted using the L and J keys, while a central light generates shadows for objects in its vicinity.

- **Parameter Manipulation**: Users can increase or decrease fog intensity (F and G keys), reveal shadow computation map (M key), and trigger automatic camera movement along Bezier curves (B key).

- **Speed Control**: Holding LSHIFT enables a "sprint" mode, greatly increasing camera navigation speed.

- **Threaded Animation**: Separate thread controls camera movement along spline-based curves.

## Scene Description

The virtual scene includes:

- Farm area with hills and terrain variation.

- Mountains acting as borders.

- Rocky hill, rocks, trees, and fences with cows.

- Dynamic lighting and shading effects.

## Code Overview

1. **Model Loading and Rendering**: Utilizes custom Model3D class to load and render level, trees, and skybox.

2. **Shaders and Uniforms**: Defines shaders for different objects and passes necessary parameters via uniforms.

3. **Depth Maps and Shadow Mapping**: Generates depth map texture to create shadows.

4. **Scene Rendering**: Renders the scene using appropriate shaders and applies shadows using light-space transformation matrix.

5. **Skybox Rendering**: Renders the skybox using a cubemap shader.

6. **User Input Handling**: Captures keyboard and mouse input for camera movement and parameter adjustments.

7. **Threaded Animation**: Controls camera movement along spline-based curves using a separate thread.

## User Manual

- **WASD**: Move camera in X and Z axes.

- **LCTRL/SPACEBAR**: Move camera in Y axis.

- **LSHIFT**: Hold for increased movement speed.

- **Arrow Keys**: Adjust camera orientation.

- **F/G**: Increase/Decrease fog intensity.

- **J/L**: Rotate ambient light direction.

- **M**: Reveal shadow computation map.

- **B**: Trigger Bezier curve camera movement.

- **Mouse**: Look around the scene.
