Vec3f is commonly a vector class in C++ used to represent a 3-dimensional vector with floating point values. This class is often used in graphics and physics programming to represent points in a 3D space.

Below are a few example usages of the Vec3f class with a brief description of each:

1. Adding two Vec3f objects:

Vec3f a(1.0f, 2.0f, 3.0f);
Vec3f b(4.0f, 5.0f, 6.0f);
Vec3f c = a + b;
// c is now (5.0, 7.0, 9.0)

In this example, two Vec3f objects are created and their elements are assigned values. The `+` operator is used to add the two vectors element-wise and stores the result in a new Vec3f object.

2. Computing dot product of two Vec3f objects:

Vec3f a(1.0f, 2.0f, 3.0f);
Vec3f b(4.0f, 5.0f, 6.0f);
float dotProduct = a.dot(b);
// dotProduct is now 32.0

Similar to the previous example, two Vec3f objects are created and assigned values. The `dot` function of the Vec3f class is then called to calculate the dot product of the two vectors.

3. Computing cross product of two Vec3f objects:

Vec3f a(1.0f, 0.0f, 0.0f);
Vec3f b(0.0f, 1.0f, 0.0f);
Vec3f c = a.cross(b);
// c is now (0.0, 0.0, 1.0)

In this example, two Vec3f objects are created and assigned values to represent the x and y axis, respectively. The `cross` function of the Vec3f class is then called to calculate the cross product of the two vectors. The resulting vector should be the z-axis. Vec3f is not a standard library in C++, however, it might be found in external libraries such as openFrameworks or Cinder.
