This project presents an interactive renderer inspired by G. K. Francis’s "A Topological Picture Book," showing mathematical surfaces such as the torus with hand-drawn line-art styling. It combines silhouettes, hidden lines, hatching, and labels using techniques like marching tetrahedra, principal-curvature streamlines, and GPU-based visibility handling.
