🎢 Rollercoaster Simulator – OpenGL C++

A 3D rollercoaster simulator built in C++ using OpenGL 4.6, GLFW, GLEW, and GLM.
The wagon follows a predefined track with smooth interpolation, textured train, track, frame, and plane models, and basic lighting via shaders.

Features

• Wagon moves automatically along a 3D track
• Two camera modes: follow wagon or free observer
• Textured objects: train, track, frame, plane
• Lighting with two point light sources
• Shader-based rendering (vertex + fragment)
• Wagon speed interpolation for smooth movement

Controls

Key	Action
C	Toggle observer/follow camera mode
UP Arrow	Move camera closer (observer mode)
DOWN Arrow	Move camera farther (observer mode)

Setup & Build

1. Clone the repo:

git clone https://github.com/yourusername/rollercoaster-simulator.git

Open in Visual Studio (solution file included: Rollercoaster Simulator.sln)

Make sure to set x64 or Win32 depending on your system

Add include paths for GLFW, GLEW, and GLM

Link libraries: glew32.lib, glfw3.lib, glfw3dll.lib

Build and run the solution

Place textures (czerwony_metal.png, metal.png, plane.png, zolty_metal.png) in the executable working directory
