This is a simple 3D model viewer that can load and display 3D models in the OBJ file format. It is written in C++ and uses OpenGL for rendering. Model loading is done using the Assimp library. Using GLFW for window creation and input handling and GLAD for loading OpenGL functions.
- Backpack model by Gert Gedik on Sketchfab
- Load and display 3D models in the OBJ file format
- Load models with and without textures
- Lighting using a directional light source (for the showcase it is moving slightly for more dynamic)
- Ambient, diffuse, and specular lighting
- Display the model in wireframe mode
- Rotate, pan, and zoom the camera
- Movements are controlled using the mouse and keyboard
- Rotate the model around its own axis
- Mouse movement - Rotate the camera
W,A,S,D- Move the camera forward, left, backward, and right- Arrow keys - Rotate the model around its own axis
1- Toggle wireframe mode on and offR- Reset the camera position- Mouse wheel - Zoom in and out
ESC- Close the application
- Add UI elements to adjust settings (like wireframe mode, camera speed, lightning, etc.)
- Add support for more advanced lightning models
- Add support for more file formats
- Add support for multiple models
The list of improvements is only a fraction of what could be done. The main goal is to make a simple game or simulation using this viewer.
