1.What
are blobby objects?
Some
objects do not maintain a fixed shape, but change their surface
characteristics in certain motions or when in proximity with other objects.
These objects are referred to as blobby objects, since their shapes show a
certain degree of fluidness.
2.What
are spline curves? (AU
NOV/DEC 2011 & NOV/DEC 2012)
The
term spline is a flexible strip used to produce a smooth curve through a
designated set of points. In computer graphics, the term spline curve refers
to any composite curve formed with polynomial sections satisfying specified
continuity conditions at the boundary of the pieces.
3.How to generate a spline curve?
A
spline curve is specified by giving a set of coordinate positions called as
control points. These control points are then fitted with piece wise
continuous parametric polynomial functions in one of the two ways. When
polynomial sections are fitted so that the curve passes through each control
point, the resulting curve is said to interpolate the set of control points.
When the polynomials are fitted to the general control point path without
necessarily passing through any control point the resulting curve is said to approximate
the set control points.
4.What
are called control points?
The
spline curve is specified by giving a set of coordinate positions,
called control points, which indicates the general shape of the curve.
5.When
is the curve said to interpolate the set of control points?
When polynomial
sections are fitted so that the curve passes through each control point,
the resulting curve is said to interpolate the set of control points.
