MATLAB Code Implementation for 3D Rotation

This sample program demonstrates how to implement 3D object rotation around the XYZ axes in MATLAB. The implementation utilizes rotation matrices for coordinate transformation, which are fundamental building blocks in computer graphics and animation systems.

The rotation process involves constructing separate rotation matrices for each axis using trigonometric functions. For X-axis rotation, we use Rx(θ) = [1 0 0; 0 cosθ -sinθ; 0 sinθ cosθ]. Similar matrices are implemented for Y and Z axes using MATLAB's matrix operations. The program combines these transformations through matrix multiplication to achieve compound rotations.

Key MATLAB functions employed include: plot3 for 3D visualization, meshgrid for coordinate generation, and matrix multiplication operators for applying transformations. The code structure allows for parameterized angle inputs, enabling dynamic rotation control through variables that can be modified programmatically or via user interfaces.

MATLAB's computational efficiency in matrix operations makes it particularly suitable for real-time 3D graphics applications. The implementation showcases how to handle vertex transformation, object rendering, and animation loops using MATLAB's graphics handles and timer functions.

This code serves as an educational foundation for developing more complex 3D graphics systems, including camera transformations, lighting models, and advanced rendering techniques. The modular design allows easy extension to include scaling, translation, and perspective projections.
