Transition From 1 Geometry Toa Nother

[glassfairy]

how do i get a geomtry to change from 1 form to another like turn a sphere into a cone...i want to show the transition how do i do it?

You make them topologically same and use blendshape. Normals may present a problem tough!

Example, paste into script editor and execute (ctrl+enter):

CODE
{
  $orig=polyCone -r 1 -h 2 -sx 20 -sy 17
                 -sz 12 -ax 0 1 0 -rcp 0
                 -cuv 3 -ch 1;
  move -r -os -wd 0 (2.0/3.0) 0;
  makeIdentity -apply true -t 1 -r 1 -s 1 -n 0;
  $dup=duplicate;
  for ($item in ls -fl ($orig[0]+".vtx[0:999]")){
    vector $vec;
    $vec= pointPosition $item;
    $vec=unit($vec);
    move -ws ($vec.x) ($vec.y) ($vec.z) $item;
  }
  $blend=blendShape $orig[0] $dup[0];
  delete $orig[0];
  setKeyframe -t 0 -v 0   ($blend[0]+"."+$orig[0]);
  setKeyframe -t 100 -v 1 ($blend[0]+"."+$orig[0]);
  playbackOptions -min 0 -max 100 -loop "oscillate";
  play -forward true;
}

PS: you may find anything to sphere (especially a simple objet like cube or cone, but not a torus which is a bit tricky) is possibly the easiest morph there is as all other things you would do in reality would be much much harder to do.

hi thanx...

will this script work even when for transition of a part of body to another shape...like say a sphere i want just the top part to change to cone.

will the script u gave work

No, its also not a script, really. Its a journal of my session. So its basically just a recoding of what i did to achive this particular scene (its bascially copypasted form the script editor, names have just been variabelized). Each mesh in existence is separate and needs its own blend design.

PS: if your interested more in what i actually did in sequence then its possible to expand.
CODE
proc psrf(){
  pause -sec 0;
  refresh -cv;
}

{
  $orig=polyCone -r 1 -h 2 -sx 20 -sy 17
                 -sz 12 -ax 0 1 0 -rcp 0
                 -cuv 3 -ch 1;
  move -r -os -wd 0 (2.0/3.0) 0;
  makeIdentity -apply true -t 1 -r 1 -s 1 -n 0;
  psrf;

  $dup=duplicate;
  for($i=0;$i<10;$i++){
      move -r (0.3) 0 0;
      psrf;
  }
  for ($item in ls -fl ($orig[0]+".vtx[0:999]")){
    vector $vec;
    $vec= pointPosition $item;
    $vec=unit($vec);
    move -ws ($vec.x) ($vec.y) ($vec.z) $item;
    psrf;
  }
  $blend=blendShape $orig[0] $dup[0];
  delete $orig[0];
  setKeyframe -t 0 -v 0   ($blend[0]+"."+$orig[0]);
  setKeyframe -t 100 -v 1 ($blend[0]+"."+$orig[0]);
  for($i=0;$i<10;$i++){
      move -r (-0.3) 0 0;
      psrf;
  }
}
