AI Drawing Prompt Reference
Create a 3D Klein bottle surface defined by parametric equations, featuring a self-intersecting closed tube. The surface is split into two segments: the first half has a varying tube radius, while the second half twists and intersects itself, forming the classic non-orientable topology. The surface is smooth and continuous, rendered with a semi-transparent or solid color to emphasize structure. Construct by defining parameters from 0 to 2π for both the loop and cross-section angles, then combine piecewise functions to generate the surface, and display in a 3D view to show its spatial curvature and intersection.
