OpenGL Model Viewer

OpenGL Model Viewer is a simple model viewer that uses OpenGL to render 3D models. It is written in C++ and uses the GLFW library for window management and the GLAD library for OpenGL function loading. The model viewer is capable of loading models in the Wavefront OBJ format and rendering them using OpenGL by utilizing the assimp library.

Getting Started

Prerequisites

The following libraries are required to build the project:

Library	Info	Link
GLFW	Lightweight utility library for use with OpenGL	Website
glad	Library for OpenGL function loading	Website
glm	Mathematics library for graphics software based on the OpenGL	Website
assimp	Library to load various 3d file formats into a shared, in-memory format.	Website
inih	Simple .INI file parser	Website

Installing

• Clone the repository into the machine

git clone https://github.com/DavidNg32/OpenGL-ModelViewer.git

• Build the project using CMake
• Run the model viewer executable

Program Details

• The program reads the configuration file config.ini to load the model file and the shader files.
• The program has a simple camera system that allows the user to move the camera around the model.
• There is a placeholder model available for the user to run in the assets folder.
• If you want a custom model, you can add the obj. file to the assets folder and change the path in the main file.
