The `getPoint` function in C++ is a method that calculates and returns a specific point along a ray. This point is determined based on the input values of the starting point of the ray and the direction of the ray. The function uses the equation `point = startPoint + direction * distance`, where `startPoint` is the initial point of the ray, `direction` is the direction vector of the ray, and `distance` is the parameter representing the distance from the starting point. By providing a specific distance, the `getPoint` function allows us to determine a point at that distance along the ray.
