# Curves and Surfaces

This is a curves and surfaces modelling program.It is a basic modelling program where surfaces and curves are created from a series of points using Splines or NURBS. The number of interpolation steps is variabl for both curves and surfaces.

Node picking uses an unprojected z-buffer depth at the cursor position to find the cursor point in 3D. Then the nearest node (or curve) to that point is selcted. Nodes of a curve can be deleted or added on the fly.
