Extracting disconnected pieces from a mesh

[Julio Jerez]

ha ok I will debug it tonight with that sample mesh.
thanks for the sample.

all right I re enable my implemnetaion again.

In the cow mesh that has abput 1500 vetex, Mamou take abput 40 secund to make it, Netwon's take less that halh a secund, about 70 time faster.

tonight I will work to fix the convexity metric bug and add the fix for the concaves faces left overs. that should complete this task for good

Wow! That's a lot better than I was expecting I tried the latest HACD on a cow with 2770 vertices and it parsed in about 15 seconds using the HACD default settings. Here's a little video of how it works in my project now.http://www.hurleyworks.com/media/flash/CompositeCow/CompositeCow.html

Looking for to testing the new version out

Thanks!

I download the lates version on saturday, so I thionk we have the same,
teh cow took a very long time, so I deciomated in 3dxMax to 1400 vertices.

my 40 secund convex constrution is in debug mode. in release is about 10 to 15 like you say.
the newton one is less than a secund, but it is not for prime time yet.

tonight I will go over again over the concavity heuristic, and tomorroy I will add the extension to handle the concave island.
then maybe you can try, and see if it work.
then I will send the sugestion to him again to see if he wants to added to the original code base.

Ok I see the problem, my heusritic to preserve the conncet pirce is no good, because I simple add the confiction face as new edge at teh end of the list.

that thgsi in fact make only one segmen and all right, but each shared vertes generate one new segment.
I have a better histic now, and I am fixxing it. I will take me more than one night to get it, but it will be very, very good.

thank you for showing me that case, very very good because improves reliability of the MeshEeffct tool.
stan by I will upload a newer version as sonn as I get it going.

I'm glad to help! Looking for to testing the new solution.
