This branch is also known as '''geometric modelling''' and '''computer-aided geometric design''' (CAGD).

Core problems are curve and surface modelling and representation.

The most important instruments here are [[parametric curve]]s and [[parametric surface]]s, such as [[Bézier curve]]s, [[spline (mathematics)|spline]] curves and surfaces. An important non-parametric approach is the [[level-set method]].

Application areas of computational geometry include shipbuilding, aircraft, and automotive industries.
