Re: [Bf-committers] Mesh curvature estimation
There was one in 2010, here is the page of the project : http://wiki.blender.org/index.php/User:Rohith291991/Gsoc2010/Proposal I spent a bit of time discussing about it with Rohith on IRC, and provided some code I had written for a partial implementation of mixed integer quadrangulations into an other software. Last time we discussed about it about one year ago, he was struggling to extract a mesh from the parametrization. Yet, I don't know if the direction field was still manually generated, but I think he used the code I gave him to build the parametrization from a direction field. I'll try to go over his code to see if I can guess how far he went. Anyway, I don't know what's left of this project, and what can be recovered. Still, if you want to resurrect this project, and think I could be of any help, please let me know, and I'll send you my code as well, and we can arrange a meeting on IRC. -- Vincent. - Mail original - I dont think the MIQ project got very far, since I've offered to implement this once my work on compositor / mask editor is done, and my offer was generally greeted with much happiness that someone was going to do this... noone even mentioned to me that anyone did a gsoc on it... so im guessing it didn't go TOO far... but maybe I'm wrong... idk.

My cursory examination of the Blender source (basically just grepping for curvature) didn't turn up any code for this, so I ported the (GPLv2) curvature code from the trimesh2 lib [2] to Blender. That code is based on the paper Estimating Curvatures and Their Derivatives on Triangle Meshes [3]. Dunno if this is useful to anyone else, but I've pushed a Blender branch [4] containing the curvature calculation (in blenlib/intern/curvature.c), as well as a test modifier that displays the curvature vectors. Screenshot with Suzanne: http://www.pasteall.org/pic/show.php?id=21557 Notes: The original code was in C++; I converted it to C and switched the math stuff over to blenlib and the types to MVert/MFace/etc. The per-vertex output is the two principal curvatures and two direction vectors. I haven't updated the code to handle quads yet, it'll assert() if it encounters a non-triangle face. I've only just gotten this working, so there are definitely bugs in it yet. :) Thanks, -Nicholas [1] http://en.wikipedia.org/wiki/Principal_curvature [2] http://gfx.cs.princeton.edu/proj/trimesh2/ [3] http://gfx.cs.princeton.edu/pubs/_2004_ECA/ [4] https://gitorious.org/~nicholasbishop/blenderprojects/nicholasbishop-blender/commits/tri-curvature Hi, There was a gsoc project last year [1] about the implementation of mixed integer quadrangulationsa [2] into blender.

One other idea just jumped up at me. Write a python add on for the old software that would allow for loading of the new format.

[Bf-committers] Boost VS2010 win libs
Hey Alexander, You committed x64 Boost libs for msvc 2010 a few days ago. But they are not used from within cmake/scons yet?! People report issues with it on the mailing list and in forums. There are two possibilities, as we officially don't support vs2010 from our side: 1) Please fix the issues, and maintain the libs. 2) Remove them from SVN again. Our libs in svn are there to build blender (especially for release), if there are (experimental) libs which can be only used with tweaking or not work at all, they can be provided via a third party website as zip archive or whatever as well. I don't mind libs in svn for mingw or msvc2010 (again, they are not used for official releases) but if they are in svn, they should work and not just waste huge amounts of space. Thanks.

Re: [Bf-committers] Updated BMesh Merge Proposal
There are many options here, I was going to list all the ones I could think of but most have some fairly annoying drawbacks. Currently BMesh triangulates the mesh when loaded in trunk or 2.4x, You could argue both ways... since mesh data is core to most blender projects... a) being forwards compatible highly important. b) triangulation of quads is so destructive - users would be better off exporting to an intermediate format then using new blendfiles in an older blender. Not crashing gives the appearance of working but infact its still quite limited, people aren't seriously going to take meshes with UV's, vertex colors etc and load them in an older blender to continue working. IMHO possible practical options are... * do nothing (allow crashing). * solve crash loading bmesh files for 2.61+, this ofcourse wont help 2.60 or older but at least allows loading in a few previous releases. * make a token effort - (what I'm proposing, load in triangulated mesh data) * write full edge and face data into the file (would make file larger since it would need to save faces twice, not to mention uv, vertex color layers etc, also if quite some work to do this and know to ignore edge data which doesn't exist for ngons). * New save option/mode Save as 2.60 compatible blend as suggested, I'm not keen on this option, mainly because it introduces the overhead of having multiple ways to save a blend file and gives us more work to support, but it could be made to work well and at least wont slow down regular saving as with what I suggested initially.
