AI Drawing Prompt Reference

Visualize a 3D Möbius strip with its normal vectors to highlight the one-sided surface. The Möbius strip is created using a sine function, and normal vectors extend outward from the central line, showing their relationship with the surface. Start by drawing the surface of the Möbius strip, then generate multiple normal vectors on it, and finally connect the vectors to the central line to clearly display the geometric relationships.
