Vector3d is a class in C++ used to represent a three-dimensional vector with x, y, and z components. It is commonly used in 3D graphics and physics simulations.

Here are some examples of using Vector3d:

Example 1: Initializing a Vector3d with values

#include 

Eigen::Vector3d x(1.0, 2.0, 3.0);

This example initializes a Vector3d object named x with the values x=1.0, y=2.0, and z=3.0 using the Eigen package library.

Example 2: Vector addition and subtraction

x = Eigen::Vector3d(1.0, 2.0, 3.0);
Eigen::Vector3d y(2.0, 3.0, 4.0);

Eigen::Vector3d sum = x + y;
Eigen::Vector3d diff = x - y;

This example shows how to perform vector addition and subtraction using Vector3d objects. We create two Vector3d objects x and y, then add them together to get the sum and subtract one from the other to get the difference.

Example 3: Dot product and cross product

x = Eigen::Vector3d(1.0, 2.0, 3.0);
y = Eigen::Vector3d(2.0, 3.0, 4.0);

double dot = x.dot(y);
Eigen::Vector3d cross = x.cross(y);

This example demonstrates how to calculate the dot product and cross product of two Vector3d objects. The dot product is calculated using the dot() method and the cross product is calculated using the cross() method. The package library used in these examples is the Eigen package, which is a C++ template library for linear algebra: matrix and vector operations, numerical solvers, and related algorithms.
