aldraco

Create a mini-application called 'DracoMeshViewer' that allows users to visualize and manipulate 3D models compressed using Draco compression. This application will leverage the 'aldraco' Python package to handle Draco-compressed files efficiently. The goal is to provide a user-friendly interface where users can upload Draco-compressed 3D model files (.drc), view them in real-time, and apply basic transformations such as rotation, scaling, and translation. Additionally, the application should support exporting the decompressed model back into a standard 3D file format like .obj.

Steps to develop 'DracoMeshViewer':
1. Set up a basic Python environment with necessary dependencies including 'aldraco', 'PyOpenGL', and 'pygame'.
2. Implement a function to load Draco-compressed files using 'aldraco', which will decode the mesh data into vertices and indices.
3. Integrate PyOpenGL to render the decoded 3D model in real-time within the pygame window.
4. Develop a simple GUI using pygame for file input/output operations, displaying the loaded 3D model, and allowing users to interact with it through mouse and keyboard inputs.
5. Add functionality to apply transformations (rotation, scaling, translation) to the 3D model in real-time based on user interactions.
6. Include an export feature that saves the current state of the 3D model (after any applied transformations) back into a standard 3D file format like .obj.
7. Ensure the application handles errors gracefully, providing informative messages when issues occur during file loading or saving processes.
8. Optimize performance for smooth real-time rendering and interaction.
9. Document the code thoroughly and create a README.md file explaining how to install and run the application, along with a brief description of the 'aldraco' package and its role in the application.
