the nurbs animation menu
____________________________________________________________________________________
Introduction
Nurbs models can be transformed in time by animating both the contour and the
spine. It can also be animated in surface mode, but not together with animations
for spine and/or contour.
It is possible to read in a contour, spine, or surface from disk and fix it on a
certain frame. In this way it is possible to morph from a swing to a sweep nurbs
model.
The contours, spines, and surfaces do not need the same number of points when
fixed on different frame numbers.
Animations will be automatically saved when using save model in the nurbs mode
menu. When importing an animated Nurbs model in GIG using import nurbs, the
time curves for the Nurbs model will be placed and can be transformed in the
animation menu of GIG.
