Bmesh surprise by Jooedh: Super Knife Tool, requires testers to complete Bmesh

Ace_Dragon · September 24, 2010, 7:03pm

Looks like a vastly improved knife tool has made it to the Bmesh branch

http://lists.blender.org/pipermail/bf-blender-cvs/2010-September/031306.html

Also, if people don’t know yet, Joeedh mentions in the commit that people testing Bmesh and reporting bugs and shortfalls are right now almost a requirement to see this in Trunk, so the Graphicall builders should fire up the compilers so he can have testers.

Said it before and here I go again. I would love to test this, but I still can’t build it with scons.

I believe this is the same build error I’ve asked about previously. Is there a Bmesh bug report page somewhere?

I get:

Haven’t been able to build bmesh for some time

Same issue that papy’s one.

I have already mentioned it on blenderartists’ forums.
We can’t build Bmesh with scons on ubuntu since several months because of it.
Even if we disable all build optimizations.

I succeed with make.

I like the green pointer and the lines with points. It is cool.

Unfortunately, you have to start and end cut line on the mesh.
If you click outside of the mesh, it create vertices outside of the mesh.
These vertices move to previous viewpoint if you rotate 3dview.

Uploaded with ImageShack.us

There was the same kind of problem with grease pencil.
If you click on an icon of the header, you must do a ctrl press to avoid this kind of problem.

Sometimes, pointer disappears.
Sometimes, it is always snapped to vertices on Face Selection Mode.
I did not understand why.

There is no possibility to snap pointer on edge’s middle.

Wow…>> Super knife tool <<…
Sound like extra Weapon for fighting with “PRO” packages.

Yes,support undo, need it…now cut…cut…cut…

Gustav_Goransson · September 25, 2010, 2:15am

I’m can’t compile either (scons+msvc, win64). I hope they get fixes soon, otherwise it’s hard for us to provide feedback…

Sweet a new bmesh playground.
Compiling went out fine here on Linux64bit (CMake only). I’ll test it later this weekend.

tyrant_monkey · September 25, 2010, 3:10am

where exactly do you report bugs for bmesh, does the bugtracker also work for branches or is it only for trunk.

Tea_Monster · September 25, 2010, 3:14am

Awaiting Windows build.

SilenceBe · September 25, 2010, 4:34am

I’ve asked this a 2 weeks ago on the blog (but it is still waiting moderation) Bmesh would really benefit if there was some bugtracker available. We can post remarks in this forum but I don’t even know if jooedh follows these topics.

I will give the build a try when a windows version is available.

tyrant_monkey · September 25, 2010, 6:03am

gustav goransson opened up a thread a few bmesh bugs collected so perharps someone should point joe to that thread its not ideal but at least its better than zero feedback

I will test and play around when a windows build appears

Carrozza · September 25, 2010, 6:22am

Great news!
I’m watching Graphicall for a fresh 64 bit build, and then :RocknRoll:

Tea_Monster · September 25, 2010, 6:28am

Build it and they will come…

frigi · September 25, 2010, 7:21am

I’ve sent joe a patch to fix the build errors a while ago but he must have forgotten.
By now he already fixed some of the issues by himself but one is still missing. You can download a patch for that here until he takes care of it in the branch.

kakapo · September 25, 2010, 10:06am

how is performance with current bmesh builds? is there a noticeable difference to the old mesh system?

AndreasGalster · September 25, 2010, 10:11am

Waiting for a windows build :)!

kernond · September 25, 2010, 10:28am

Good news, but a key project like this (that’s also holding up other development) needs a little bit better organization than this.

To whom it concerns:
Are there any plans to address the problems people have mentioned in this thread? (build ability, bug tracker, some centralized place for providing feedback)

EDIT: Found a thread for BMESH Feedback at http://blenderartists.org/forum/showthread.php?t=192498 (I don’t know if the dev visits it, though.)

At this time, I don’t even see a blog post on the dev’s site. That would be a good place for immediate feedback.

AndreasGalster · September 25, 2010, 12:09pm

Thanks for the overview!

Sim88 · September 26, 2010, 2:20am

He’s really trying to get it to compile, now I get
