ros / convex_decomposition Goto Github PK

In my looking around re. #5 , I mentioned finding that John Ratcliff appears to have labeled his own library as deprecated. I thought I'd split this out as a separate issue.

I'm very new to ROS so this discussion is over my head, but I thought it should at least be mentioned that the creator of this library seems to point others to use something else. From his blog:

Many people come to this weblog because they are searching on terms for 'Convex Decomposition'. This blog post is to announce that there is a much, much, better open source implementation than the one I did. I suppose I can take some tiny credit as my work appears to have inspired the authors of the new algorithm but that's not really saying much. All credit where credit is due and the open source implementation released by Khaled Mamou is vastly superior to the brute force approach that mine took. His is much more elegant and also solves a lot of extremely hard problems; such as objects with holes in them (something my algorithm could not deal with). His also does not suffer with the problem mine had with excessive recursion depths producing hollow interiors.

You can find the paper for this algorithm at this location:
ftp://ftp.elet.polimi.it/users/Stefano.Tubaro/ICIP_USB_Proceedings_v2/pdfs/0003501.pdf

You can download the source to HACD from this location on SourceForge
http://sourceforge.net/projects/hacd/

With this announcement I will no longer be supporting my legacy ConvexDecomposition code in any way. I am switching to using HADC in all of my projects. I recommend you do the same.

The ftp link is broken, but Mamou refers to his publications listing on the post where he announces HACD, which yields this alternate link to his IEEE 2009 paper.

Are there any plans to release this package for ROS Melodic?

Would you mind releasing convex_decomposition to ROS Noetic? It looks like all of its dependencies have been released, and recursively 29 repos need it.

I'm not sure how much work it will need. The Noetic Migration Guide or the guide about transitioning ROS packages to Python 3 may be useful.

Hello,

I'm just getting started with ROS, learning from a colleague. I was building one of his packages and got an error related to convex_decomposition, leading me to check the ROS wiki to make sure I had it or the higher-level pkg containing it installed.

I'm used to seeing a github link for ROS packages, but found that it just points to John Ratcliff's blog (the main page, not even a page about convex_decomposition). Given that this repo exists, I would have expected the wiki to point here.

In any case, I just got wiki editing privileges and went to change the wiki page to at least add the link to this repo, but found that it appears to auto generate from the package.xml:

## repository: https://code.ros.org/svn/ros-pkg
<<PackageHeader(convex_decomposition)>>

So, I went to check for that info here to find:

<url type="website">http://codesuppository.blogspot.com</url>
<url type="bugtracker">http://kforge.ros.org/robotmodel/Trac</url>
<url type="repository">http://kforge.ros.org/robotmodel/convex_decomposition</url>

After a little more digging:

• kforge appears to be down or not responding
• hits for convex_decomposition site:http://codesuppository.blogspot.com get me mostly posts from 2006 and 2009, with some from 2011
• posts discussing his library generally feature a disclaimer that it's been replaced by something better and not to use it.

So, this is just to post an inquiry from a noob on whether this information is correct and up to date. Thanks for taking a look.

@BryceVoort and I work together, he has given permission to transfer over it as he no longer maintains this package.

I'll take it over to release for ROS Kinetic.

Hi @BryceVoort, @TheDash and convex_decomposition maintainers!

As you may know the next ROS release Lunar Loggerhead is around the corner 🎉
This package being a dependency of several tutorials, it would be great to do a release on ROS Lunar asap.

Thanks!

This is a dependency of pr2_description which is used in several tutorials, so it would be great try and get this released soon.

It is required for the pr2_common stack https://github.com/PR2/pr2_common #234
