Curve-Based Shape Modeling — a Tutorial

by Pushkar Joshi

Three-dimensional shape modeling, or simply modeling, creates a computer representation of a 3D shape. The 3D shape could be constructed from scratch, from existing 2D shapes, or by deforming preexisting 3D shapes. Modeling has applications in CAD, creative design, entertainment (video games and movies), ideation (concept shapes), and communication of shapes in scientific disciplines.
