[Maya2osg-users] Blend shapes

[Javier T. <jav...@gm...>]

  Hi all,

  Maya2OSG now exports blend shapes to osgAnimation::MorphGeometry nodes.
It's a preliminar version so testing and feedback is welcome.

  The built-in preview command (osgpreview) has a minimal blend shape
previewer, using the following keys:

  plus - Select next MorphGeometry
  minus - Select previous MorphGeometry
  left - Select previous MorphTarget
  right - Select next MorphTarget
  up - Increase MorphTarget weight
  down - Decrease MorphTarget weight

  I uploaded also a test scene named test_blendshapes.ma to test the export.
It's an ugly deformed sphere. Beautiful test models are also welcome  :)

  Peter, I changed lots of things in mesh.{cpp,h}, I hope not to have broken
anything. Let me know if you find any problem. Among other things, there
were a lot of static attributes that I moved to local variables in the
minimum scope where they are used. This way we minimize the unexpected side
effects and is less error-prone, and the code is easier to follow. Maybe in
any case there could be a good reason to be there, but not as the code is
now. I don't know what will be the connection between the rigging/skinning
code with mesh.cpp, but I think we can solve it without these static
attributes, just passing the needed information as parameters to functions
or methods.

  Well... that's all for today. More to come.


  Cheers!
