[Bf-committers] Bmesh question

[raulf at info.upr.edu.cu]

Hi

 The main drawback that makes Editmode unusable for high polycounts is
that for nearly every operation the code has to iterate over every vert,
edge and face, in any combination/amount depending on the tool.
 That makes the performance scaling with the number of geometry components
pretty bad, there's no locality, local transformations are handled only
with flags, checking over the rest of the elements where the flag has the
correct value :(

 One of the thing that makes sculptris so smooth at high polycounts is
that it seems to edit the topology in a local way, the tool only has to
iterate over the geometry that is rigth under the brush.

  my question is if Bmesh will make possible to work in a local way or if
is just a drop in replacement for the current mesh with no performance
imporvement in the Editmode?
