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.

Mesh Modifier Descriptions

Basic Modifiers

• BendModifier: Bends the mesh along a specified axis.
• BevelEdgesModifier: Creates a bevel along the edges of the mesh.
• BevelFacesModifier: Creates a bevel around the faces of the mesh.
• BevelVerticesModifier: Creates a bevel around the vertices of the mesh.
• CenterAtModifier: Centers the mesh at a specific point.
• CrocodileModifier:
• ExtrudeModifier: Extrudes the faces of the mesh along their normals.
• FitToAABBModifier: Scales and /translates???/ the mesh to fit within an axis-aligned bounding box.
• FlipFacesModifier: Flips the orientation of the faces of the mesh.
• HolesModifier: Creates holes in the mesh.
• InsetModifier: Insets the faces of the mesh inward.
• NoiseModifier: Adds noise to the vertex positions of the mesh. Normals!
• PushPullModifier: Pushes or pulls the faces of the mesh along their normals.
• RemoveDoubleVerticesModifier: Removes duplicate vertices from the mesh.
• RotateXModifier: Rotates the mesh around the X-axis.
• RotateYModifier: Rotates the mesh around the Y-axis.
• RotateZModifier: Rotates the mesh around the Z-axis.
• ScaleModifier: Scales the mesh uniformly or non-uniformly.
• SmoothModifier: Smoothes the mesh by averaging vertex positions. ???
• SolidifyModifier: Adds thickness to the faces of the mesh.
• SpherifyModifier: Spherifies the mesh.
• TranslateModifier: Translates the mesh.
• UpdateFaceNormalsModifier Updates the face normals of the mesh.
• WireframeModifier: Converts the mesh to a wireframe representation. ???

Subdivision Modifiers

• CatmullClarkModifier: Subdivides the mesh using the Catmull-Clark subdivision scheme.
• DooSabinModifier: Subdivides the mesh using the Doo-Sabin subdivision scheme.
• LinearSubdivisionModifier: Subdivides the mesh using a linear subdivision scheme.
• PlanarMidEdgeCenterModifier: Subdivides the mesh by splitting edges and connecting their midpoints.
• PlanarMidEdgeModifier: Subdivides the mesh by splitting edges and connecting their midpoints to the face centroids.
• PlanarVertexCenterModifier: Subdivides the mesh by connecting vertices to face centroids.
• PlanarVertexMidEdgeCenterModifier: Subdivides the mesh by connecting vertices, edge midpoints, and face centroids.
• PokeFacesModifier: Adds a vertex to the center of each face.
• QuadsToTrianglesModifier: Converts quad faces to triangles.

• Goal: Further refactoring of the mesh class following the refactoring plan.
• Removed the update face normals method from the mesh class. Implemented a new modifier UpdateFaceNormalsModifier
• Removed the scaled copy from the mesh class
• The scaled copy should live as own creator class. The current implementation was wrong anyways, caus it did not copy face attributes.

// public Mesh3D scaledCopy(Vector3f scale) { // Mesh3D copy = new Mesh3D(); // List vertices = copy.vertices; // List faces = copy.faces; // // for (Vector3f v : this.vertices) // vertices.add(new Vector3f(v).multLocal(scale)); // // for (Face3D f : this.faces) // faces.add(new Face3D(f)); // // return copy; //}

• Removed the getSelection(String tag) from the mesh class. It exists as face selection option already and it is not used within the library.
• Removed rotateX from the mesh class
