ObjViewer

ObjViewer is a cross-platform 3D model viewer built using C++ and OpenGL. Currently, it supports the following features:

• Loading arbitrary .obj geometry files with associated .mtl material files
• An interactive orbit camera system with yaw/pitch rotation and zooming
• Showing/hiding individual groups defined in the .obj file
• Rendering transparent materials using back-to-front sorting
• Clicking on parts of the model to select the corresponding group
• Phong shading with adjustable ambient, diffuse, specular, and emissive components

Building & Dependencies

This project uses the following dependencies in addition to OpenGL: GLFW, GLM, tinyobjloader, Glad, Dear ImGui.

To build the project, run the following commands:

git submodule update --init --recursive
mkdir build
cd build
cmake ..
make

The executable will then be built at ./objviewer.

Usage

./objviewer ../examples/bmw.obj

Note: example .obj and .mtl files are taken from here.
