3D Transformation System

Author: Saurabh Chikate
Language: C++
Domain: 3D Geometry / CAD / Graphics

The 3D Transformation System is a C++ application that performs 3D geometric transformations using vectors and matrices.
It allows you to apply translation, rotation, and scaling on 3D points, demonstrating fundamental concepts used in CAD and visualization software.

Key highlights:

• Implementation of Matrix4x4 and Vector3D classes.
• Operator overloading for matrix-vector and matrix-matrix operations.
• Strong use of OOP principles (encapsulation, static methods, constructors).
• Handles homogeneous coordinates for transformations.

• Translate, scale, and rotate a 3D vector.
• Combine multiple transformations in any order.
• Interactive console input for dynamic testing.
• Easy-to-read output of transformed vectors.

1. Clone or download the project.
2. Ensure you have the following files:
   • vector3d.h
   • matrix4x4.h
   • main.cpp
3. Compile using a C++ compiler (e.g., g++):

   g++ main.cpp -o Transform3D

4. Run the program:

   ```bash
   ./Transform3D
   ```
5. Follow the on-screen prompts to input vectors and apply transformations.

## 🧩 Example

```
Enter vector (x y z): 1 2 3
Choose Transformation: 2
Enter scale (sx sy sz): 2 2 2
Choose Transformation: 1
Enter translation (tx ty tz): 1 0 0
Choose Transformation: 6
Original Vector: Vector3D(1, 2, 3)
Transformed Vector: Vector3D(3, 4, 6)
```
