        MORPH: how it's done.



  Let us remember the good old days.
When INSULT considered top arts and
all fell from its effects. Was there one
prikolchik - MORPH said. In this
article we will try to figure out the principle of
his work (or rather not quite it, but my
implementation MORPH'a).



  What is the MORPH? MORPH (as claimed by the TSB), the word 
foreign. More than anything she could not tell. Will have 
define yourself. Um ... Well ... MORPH - is the effect of soft 
flowing one image to another. At

least, he looks like.


                    Attached you find
                    Dete program to
                    Thoraya morfiruet iso
                    mapping as

                    indicated on the left.


  Now about the algorithm works.


   1. Read into memory are the two images:

      the initial and final images.



   2. Scan the two images and create a

      Memory tables are included pixels



   3. Believe their numbers.



   4. If one of the images pixels

      less, then we bring the number

      up more by random choice
      pa from the existing ones.



   5. Mix the coordinates of all points

      randomly.



   6. We take the coordinates of the first points of the first
      first and second screens, we compute

      the distance between them - S. Partition
      Vai a way to (the number of frames -

      a) parts. At each frame

      point of the first screen tends to be
      mitsya to the point of the second screen

      given step.



   7. Moving the point of a given number of cadmium
      moat.


  The program, which is attached to the magazine has all the 
necessary comments.
