21. Parameterization & UV Unwrapping

Parameterization maps complex 3D curved surfaces onto the flat 2D coordinate plane. This chapter covers Tutte's spring embedding theorem, Least Squares Conformal Maps (LSCM), As-Rigid-As-Possible (ARAP) flattening, and conformal versus authalic distortion energy metrics.
