[Bf-committers] Decimation / Surface Simplifier...

[Jaevixa McNomera]

Hi everyone! :)

No worries about ASM issues, I did it all inside one function and it's easy
to pre-process it out :)  I knew it'd be a problem from the start but still
wanted to see how much faster it'd get if I did one version almost
completely in ASM.

As for the different simplification algorithms, they are selectable during
runtime from inside the modifier panel. (like how we can pick anti-aliasing
method now in the render panel...)

In reply to a few of the mails in this list:

HI Moguri!!!!!! :) It's nice to see a familiar name in here!  (I miss all of
you!!!)
I will do my best to get on IRC but the WiFi in the hospital here is weak
signal where I am.

About Quad Remeshing, already taken into consideration. :) I constructed the
mesh reducer in such a way that you can specify a topological output model
of whatever you'd like.

Could anyone reading this send me a real-life 3-4 million polygon object for
me to test against?

The largest real world usage object I've tested was a little over 2 million,
and I'd sure like to try it on some other cool stuff. :)

Regarding BMesh, I spoke with Joeedh at length about this a while back. So
long as nothing major has changed in BMesh since then, it'll work fine with
ngon input, and can create ngon output as well.

I also discussed some finer points of this system with ZanQdo about how this
would affect a mesh with vertex groups used with an armature. We can still
discuss it, but with his wisdom and experience in animating, I think he
filled me in on all the most important things to consider. :)   **thanks
Danny!**

If there is anyone reading this that worked on the rendering engine or the
baking system, I do have a question or two... I can explain in great detail
in another email.

And Ton, you're the best! The first time I got to put a real shirt on
instead of just a hospital gown, I put on the custom blender tshirt!!!!
Thanks SO much!!!!!!!!!!

Well, Hi again to all my friends out there! I miss you all a whole bunch!!!!
and I don't have your email but I miss you too Briggs!

God Bless you everyone!  -- I moved BOTH my ankles for the 1st time today in
MONTHS!!!!  AAHH!!!! I'm so excited! Can't wait to walk again!

Jae  :)
