Mesh-Viewer

A C++/OpenGL mesh viewer for OBJ format models.

Features

This application allows you to view 3D models in OBJ format with different materials & light models.

Under development, new features are on the way ;)

Camera:

• WASD for close-far and left-right movement
• Mouse drag for rotation
• Mouse scroll for zoom

Rendering:

• Constant ambient light
• Blinn-Phong
  • Gamma Correction
  • HDR Tone Mapping

Besides the predefined shaders, you can add custom shaders in src/shader directory and use it in the code.

Model:

• OBJ file for mesh vertices, normals and UVs
• MTL file for materials

An example model of Lumine (Genshin Impact) is attached in resource/lumine directory. You can add custom models and load it in the code.

Build & Run

This project is configured for Windows 11 64-bit & MSVC 2022. If you are using a different toolchain or platform, the CMakeList.txt may not work normally on your environment.

• mkdir build && cd build
• cmake ..
• Open Mesh-Viewer.sln and build project in Visual Studio.
• Find binaries in Release directory.

Currently, shader & resource path is hard-coded in main.cpp, so the Mesh-Viewer.exe file should be placed at a bin directory, along with src/shader and resource directory. Please refer to the v0.1 release pack.
