Rotating a 3D object mentally vs computationally
Fun fact:
In computer graphics programming, rotating a 3D object would require a matrix multiplication which generally takes same amount of computational steps.
But, if we were to rotate a mental image of a 3D object in our heads, we generally tend to simulate a physical rotation simulation that creates a time difference for our computation depending on the amount of rotation applied to the object we are mentally working with.
Learned these from a computer vision lecture by the University of Colorado Boulder, where they talked about vision in neuroscience and psychology and its connections to computer systems.
