Re: Delta Mush

[Cesar Saez]

Hans Godard version (second link) seems particularly interesting as he is
using the mush deformations to get the skin/envelope weighting (as close as
possible).

It's a mix of the mush deformer and this papers:

Hello,
  

  I would like to share with you my
      Delta Mush ICE compounds (Or what I guess delta mush is
  :P). I am pretty sure is not the best implementation of
      Delta Mush (due my null maths skills ) but it is working
  kind of OK.  (Very slow that is true  )
  

  This version is using a simple
  average neighbours smoothing (I think this is a uniform
  Laplacian), without any weighted average. That means that
  can cause smoothing artifacts if the mesh have big
  differences between the smallest and biggest  polygons.
  This artifacts normally show up with higher mush
  iterations.
  

  One little trick that I found is
  apply a relax before apply Delta Mush.  So this uniform a
  little the size of the polygons
  

      Also I found Delta mush is very
  impressive when you only have 1 deformer x Point. is like
  Voodoo magic ;)
  

  Regarding experiments and errors,
  If the smoothing at origin is different that the smoothing
  in the final, you can control how much the detail is
  washout or exaggerate. I call it the body-builder effect.
  

  https://dl.dropboxusercontent.com/u/1530991/DeltaMush_ICE.rar

  

  I hope you like it! 
  

  if you have any improvement or
  smoothing  algorithm, please share it :)
  

  Cheers,
  Miquel 
  

  PS: you need to activate the delta
  mush in the sample scene. Check the Second ICE tree in the
  animation stack.
  PS2: Eddy share your OCD compounds,
  we want it!! ;)

Re: Delta Mush ICE

[Alok Gandhi]

Let me take the liberty to explain before Raff does. Delta of points mean
difference between two position. Let's say that you have a point in a mesh
at [x1, y1, z1] position. And then for the same mesh you apply some changes
through deformers / ops as a result this point now moves to a new position
[x2, y2, z2]. Then a Delta of Positions between these two positions of the
mesh will be - [x2-x1, y2-y1, z2-z1]. The Delta Positions would be an array
of such difference positions of all the points in the mesh. That's
mathematical definition. In simpler terms, it is just the information which
records the difference in the position of each vertex in a mesh between two
different states.

Re: Delta Mush ICE

[Raffaele Fragapane]

Given smoothing in ICE is always going to be fairly slow, I imagine if you
wanted some performance out of it using the DQ skinning compound, or even
just building up your own linear skinning, in ICE in the modelling stack
and using local shapes and the native smooth for the mush would be by far
the fastest option before taking on it with full fledged C++ custom nodes.
Unless you're only using ICE to re-apply the shape and not doing any
smoothing inside it, in which case you're probably on par.

I prototyped a delta mush in ICE to figure out my splice version

Re: Delta Mush ICE

[Raffaele Fragapane]

Delta mush isn't a smooth di per se', it's a binding state trick.
You smooth a mesh and save the delta of points from full detail to smooth
in the bind pose, you then deform and smooth out the full mesh, and lastly
re-apply the deltas back on the deformed smooth mesh to reinstate the high
frequency detail and irregularities.

A basic implementation like that is quite simple actually, and that's why
it's kinda brilliant.

It's pretty easy to do with OOTB XSI actually if you use ICE to apply
shapes after the envelope, or use ICE to skin things in the modelling stack.

Take mesh, smooth it, shape animate from smooth to HR with shapes set to
local (it will use the local reference frame of each point).
Then apply your skinning, and apply a smooth deformer on top. Lastly apply
the local shape through ICE to recomputed point framesets.
The reference frameset is trivial, Y is the normal, X or Z is the first
edge projected on the normal's plane, the last axis is the cross product of
the two.
You also have ICE facilities for that, I believe, and if they match the
same system used by local shapes they should just work.

If you instead do the skinning in ICE in the modelling stack, then you have
even less work to do, as you can use local shapes OOTB (they are meant to
preserve local transforms in shape with something live going on in the
modelling stack).

What I dont understand is, how does it
  smooth-out the visible yanks in the mesh, but while not also
  shoothing-out the nose for example? does it use the base static
  mesh shape or?
  
  nevertheless, 100% nice! :)

  Hello,


I would like to share with you my Delta
  Mush ICE compounds (Or what I guess delta mush
  is :P). I am pretty sure is not the best
  implementation of Delta Mush (due my null
  maths skills ) but it is working kind of OK.
   (Very slow that is true  )


This version is using a simple average
  neighbours smoothing (I think this is a
  uniform Laplacian), without any weighted
  average. That means that can cause smoothing
  artifacts if the mesh have big differences
  between the smallest and biggest  polygons.
  This artifacts normally show up with higher
  mush iterations.


One little trick that I found is apply a
  relax before apply Delta Mush.  So this
  uniform a little the size of the polygons


Also I found Delta mush is very impressive
  when you only have 1 deformer x Point. is like
  Voodoo magic ;)


Regarding experiments and errors, If the
  smoothing at origin is different that the
  smoothing in the final, you can control how
  much the detail is washout or exaggerate. I
  call it the body-builder effect.

I hope you like it! 


if you have any improvement or smoothing
   algorithm, please share it :)


Cheers,
Miquel 


PS: you need to activate the delta mush in
  the sample scene. Check the Second ICE tree in
  the animation stack.
PS2: Eddy share your OCD compounds, we want
  it!! ;)

Looks cool ! is this all in Ice ? or does it require another mesh to be
smoothed out ?
