To determine a bundle of planes with 2 planes, we can use the concept of linear combinations. Given two planes in 3D space, we can find the normal vectors of each plane and then take the cross product of these two normal vectors to find the direction of the line of intersection between the two planes. This line of intersection will be the axis of the bundle of planes. The angle between the two planes will determine the spread of the bundle. By varying this angle, we can generate a family of planes that form the bundle. **
