Notes

• The ScaleModifier has the potential for parallelism.
• The ScaleModifier does not need to scale if scale = 1
• Provide seed for the NoiseModifier -> testing
• The TranslateModifier does not need to translate if deltaX == deltaY == deltaZ == 0

Refactoring Plan: Mesh3D Class

• Goal To improve the extensibility, maintainability, and testability of the Mesh3D class by applying the Open-Closed Principle.

• Approach Identify Modification Operations: Identify all operations that modify the mesh, such as rotation, scaling, translation, smoothing, subdivision, etc.

• Refactor Existing Operations: Convert existing modification methods (e.g., rotateX, scale) into MeshModifier classes. Remove these methods from the Mesh3D class.
