MeshEdit is the first major component of Scotty3D, which performs 3D modeling, subdivision, and mesh processing. When implementation of this tool is completed, it will enable the user to transform a simple cube model into beautiful, organic 3D surfaces described by high-quality polygon meshes. This tool can import, modify, and export industry-standard COLLADA files, allowing Scotty3D to interact with the broader ecosystem of computer graphics software.
The `media/` subdirectory of the project contains a variety of meshes and scenes on which the implementation may be tested. The simple `cube.dae` input should be treated as the primary test case -- when properly implemented MeshEdit contains all of the modeling tools to transform this starting mesh into a variety of functional and beautiful geometries. For further testing, a collection of other models are also included in this directory, but it is not necessarily reasonable to expect every algorithm to be effective on every input. The implementer must use judgement in selecting meaningful test inputs for the algorithms in MeshEdit.
Once you implement an operation, you can test your implementation in [Model Mode](/docs/guide/model.md). See [Operation Guide](#operation-guide)
Once you implement an operation, you can test your implementation in [Model Mode](/docs/guide/model.md).
For this assignment, you will implement methods in `student/meshedit.cpp`. The following sections contain guidelines for implementing the functionality of MeshEdit:

3. Switch to `Model` mode, select the object by clicking the checkbox in `Menu`. You can now change the mesh color and perform **global operations**.
4. When an object is selected, you can also select individual vertices, edges, or faces in the scene to see their information and perform **local operations** or adjust their positions in the scene.
5. Once you have created your own object, you can export it by clicking `Export Scene` in `Layout` mode.
