Morphing - Key Frame Systems
Transformation of object shapes from one form to the other is termed as morphing as short form of metamorphism. This method can be applied to any of motion or transition relating a change in shape. To know this, see the figure 3.
In the figure 3 demonstrates the linear interpolation for transformation of two linked line segments in key frame K on to a line segment in key frame K+1. Now various vertices in both frames are similar, so simply position modifies.
However if the situation is vice versa, that is as key frame K is a Line and key frame K+1 is a pair of lines, we require to have linear interpolation for transforming a line segment in key frame K into two linked line segments in key frame K+1. When transformation is from one line to two lines and as frame K+1 has extra vertex we adjoin a vertex among 1 and 3 in frame K, to have balance among some vertices and edges in two frames
This renders a polygon surface by linearly interpolating intensity values across the surface. Intensity values for each polygon are matched with the values of adjacent polygon alon
