Notes

• The FlipFacesModifier has the potential for parallelism.
• 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
• The TranslateModifier has the potential for parallelism.
• Implement Snap to ground modifier

Some Considerations for Future Features

Mesh Modifiers

Bending Modifiers:

• Currently, we have a BendModifier that bends the mesh along the X-axis.
• Consider implementing modifiers for bending along the Y and Z axes as well.

Noise Modifier:

• The current NoiseModifier uses random noise.
• We could explore other noise types, such as Perlin noise and Simplex noise, to provide more diverse and controllable noise effects.
• To ensure consistent results and facilitate testing, we could introduce a seed parameter to the NoiseModifier.

Basic Transformations:

• We have a ScaleModifier for scaling along the X, Y, and Z axes.
• For convenience, we could add dedicated modifiers for rotations around individual axes: RotateXModifier, RotateYModifier, and RotateZModifier.

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.

• 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
• Format changes of the README.md according to max line length = 80
• Let's have some fun and implement a low poly barrel creator based on Grant Abbitts tutorial: https://www.youtube.com/watch?v=0jWLjAaIEMg&t=450s

Dev Diary

Today, I decided to not only test and refactor my library but also actively expand it. Specifically, I implemented a new MeshCreator focused on procedural assets. I used a Blender tutorial by Grant Abbitt (https://www.youtube.com/watch?v=0jWLjAaIEMg&t=450s) as a reference to create a low-poly barrel.

My goal was to procedurally generate this asset using my library, thus expanding it and honing my skills. This approach offers several advantages:

• Learning Process: It forces me to think creatively about how to achieve the desired result using the existing tools in my library.
• Documentation: I can document my development process and share my solutions with others.
• Enjoyment: It's simply fun to actively use the library and create something new.

First Steps:

I watched the tutorial carefully and considered how to implement the individual steps using my library. Initially, I focused on the simpler variant and omitted details like indentations.

Implementation:

First, I defined the parameters that describe my barrel:

• Cylinder: Number of segments, radius
• Metal Rings: Height, thickness
• Wooden Part: Height of the bottom, middle, and top sections
