Weekly Reports for Year 2013

Weeks 015 & 016 - 12/21 to 01/04

As expected, those where two less-active weeks… I spent time again trying to 'fix' binary FBX 7.3 export, fixed a few errors but still not working (this is very frustrating :/ ). As usual, spent some time on UI-related tasks (modal numinput, various small stuff) and bugs.

  • Game-dev related (bin FBX export):
    • Various fixes on FBX bin export, all trying to get exported files loading with official SDK, no luck so far it seems (see blender-io-fbx on GitHub).
    • Updated against latest master loop_normals patch (D11). Still waiting for a review.
  • General Development:
    • Usual i18n weekly update.
    • Worked more and committed modal numinput work (D61, 87cc890aef).
    • Committed new 'middle clipping' feature for long text in TEX fields & co UI controls (D114, 3c6b5b72a4).
    • Modal numinput: added back - and / shortcuts to reverser/inverse current expression (ad682f22fb).
  • Bug Tracker:
    • BT misc (general check, assign & close work).
    • Fixed #37903 Operator log serialization broken for sets (14c9899a69).
    • Fixed #37992 german NUMPAD-COMMA is not tranlated to decimal dot (1fa63b317a).
    • Fixed #38008 Bug in templates operator_nodes.py (de147a907f).
    • Fixed #38019 Edge/Vertex Slide recognises Even and Flipped as if they were numerical values (aef307cf31).
    • Fixed #38043 Text clipping when it shouldn't (56a531eb29).
Fixed: 5; Closed: 3.
  • Next week:
    • Will keep trying to understand what’s missing in FBX export to get it working more universally (sic).
    • Still waiting for a first skim-review of current loopnormals code (D11).
    • Usual UI and BT work of course...

Week 014 - 12/14 to 12/20

Spent time on binary FBX 7.3 export, mostly trying to get exported files loadable under 'official' FBX apps, with no luck so far. Probably a small detail somewhere that breaks things, readers of this format can be very touchy sometimes… And spent some time on UI-related tasks (modal numinput, various small stuff) and bugs.

  • Game-dev related (bin FBX export):
    • Various fixes on FBX bin export, and added mesh "Material" layer support (in theory, can’t really test it currently), all trying to get exported files loading with official SDK, no luck so far it seems (see blender-io-fbx on GitHub).
    • Worked on FBX structure doc.
  • General Development:
    • Usual i18n weekly update.
    • Proposed a new 'middle clipping' feature for long text in TEX fields & co UI controls (D114).
    • Worked on supporting units in modal numinput (from Campbell's review, D61).
    • Reviewed D71 (add support of smpte as time unit).
    • Proposed D119 related to D71, to support leading zeros in integers entered by users (python does not support things like '003', though '003.' would work, as it is a float literal…), got rejected.
  • Bug Tracker:
    • BT misc (general check, assign & close work).
    • Fixed #37103 Keyframing custom properties issue (51f5c994e9).
    • Fixed #37830 UILists text now right align (dce82591a7).
Fixed: 2; Closed: 3.
  • Next week:
    • Will keep trying to understand what’s missing in FBX export to get it working more universally.
    • Still waiting for a first skim-review of current loopnormals code (D11).
    • Usual UI and BT work of course...
    • Note next two weeks I’ll have less time for Blender, and won’t be online that much (thus making one week of work with two real weeks).

Week 013 - 12/07 to 12/13

Heavy binary FBX 7.3 export week again, with some more work on meshes (UVs and a few others), and mainly rough Material/texture support. Also spent quite a bit of time over upgrading install_deps.sh to OIIO 1.3.9 and OSL 1.4.0 (with c$forks of those libs to move our ugly monkey patching from the script to nice git repo, with pull requests against vanillia ones). Also worked a bit on UI-related tasks (modal numinput…). And not much time for bugs again…

  • Game-dev related (bin FBX export):
    • Worked on FBX bin export (Various fixes, added smoothing, vcols and uvs to mesh, and added basic working materials/textures support, though not yet fully functional, see blender-io-fbx on GitHub).
    • Worked on FBX structure doc.
    • Updated patch for loop normals stage I (D11).
  • General Development:
    • Worked on updating install_deps.sh for OIIO 1.39 and OSL 1.4.0 (also backported patches in this script on a git fork, should be in vanilla sources soon). (bac86a0825, dropped --all-static in 05e17242c9).
    • Updated patch for units in modal numinput (D61).
  • Bug Tracker:
    • BT misc (general check, assign & close work).

  • Next week:
    • Will keep working on bin FBX export (many things to clean up, test, enhance, finish…).
    • Will keep teasing Campbell to make a first skim-review of current loopnormals code (D11).
    • Same goes for reviewing the modal numinput on (D61) ;).
    • And BT, as usual!

Week 012 - 12/01 to 12/06

Well, much more productive week this time! We now have a basic support of binary FBX 7.3 export, with objects, cameras, lamps, and basics of meshes working. Also worked quite a bit again on UI-related tasks (modal numinput work mostly). Only drawback was for bugs - nearly did not worked over tracker…

  • General Development:
    • Usual i18n weekly update.
    • Worked on supporting units in modal numinput (D61).
    • Added new patch supporting real init values in modal numinput (D83).

    • BT misc (general check, assign & close work).
Fixed: 0; Closed: 2.
  • Next week:
    • Will finish bin FBX export basics (mostly, more mesh data like UVs, smoothing, normals, etc., and materials + textures).
    • Will chase Campbell to make a first skim-review of current loopnormals code (D11) ;).
    • Probably still some work over UI stuff.
    • Will try to find more time for BT, have a few bugs to squash there!

Week 011 - 11/23 to 11/30

Not a much productive week - especially not on what I intended to work on originally (did nearly nothing for FBX export...). Spent most of time over some not-so-small long-standing todos (uilists, remove degrees from code, etc.).

  • Game-dev related (bin FBX export):
    • … (yes, I know).
  • General Development:
    • Usual i18n weekly update.
    • Finished and committed uiList ctrl-click-rename feature (f842ce82e6 and 4c52e737df).
    • Reviewed uiList rename enhancement patch by Brecht.
    • Further addition to uiList (proper handling of copy/paste of names, d6e257d447).
    • Chased and finally fixed own regression in dropdown lists (title shows offset), caused by own 254aa8f3a0 (0570bdc13d).
    • Finished patch removing remaining degrees in Blender code (D59).
    • Worked on supporting units in modal numinput (most work done).

Fixed: 1; Closed: 0.
  • Next week:
    • Will finish the unit support in modal numinputs thing.
    • Will resume work on bin FBX export (and do nothing else until I get something!).
    • Will keep working over BT, if time available.

Week 010 - 11/16 to 11/22

Well, that was a bit of a frustrating week - far too much time spent on learning git (and finding ways to fix issues with submodules!), but I guess this was to be expected. I kept working over bin FBX exporter work (a bit, nothing usable still, was distracted by a user request for Doom3 export, should have been a simple fix but turned out to need more work :/), and kept working on click-rename in uiList (initial patch was not that much satisfying).

  • Game-dev related (bin FBX export):
    • Worked on FBX exporter.
    • Worked on Doom3 exporter.
    • Finally submitted current loop normals work for first quick review (spent a hell of a time fixing git and making 'arc diff' work…).
  • General Development:
    • Installed and learned to use arcanist… :/
    • Worked on UI task (preliminary work for uiList ctrl-click-rename feature, 6f97e194e5 and b8b7180760).

Fixed: 2; Closed: 2.
  • Next week:
    • Will keep working over BT…
    • Will keep working on bin FBX export (and try not to get distracted this time!).

Week 009 - 11/09 to 11/15

And another heavily bugtracker-oriented week… I kept working over bin FBX exporter work (had hopped to have a basic object export working by now, but still have a bit of work), and finished click-rename in uiList.

  • General Development:
    • Usual i18n weekly update.
    • Talked with Sergey and Campbell about future (git) workflow for translations.
    • Fixed a bug in uiList (visual active index was not always correct, r61214).
    • Fixed a bug in uiList, where active item labels in sublayouts would not get colored as active (need recursion in sublayouts!). Was affecting e.g. Group node inputs/outputs lists (r61125).
    • Finished uiList "clic-rename" feature.
    • Updated own work space for new GIT repositories…
    • Updated {{BugReport|…}} and added {{GitCommit|…}} templates in wiki.
  • Bug Tracker:
    • BT misc (general check, assign & close work).

Fixed: 5; Closed: 16.
  • Next week:
    • Will keep working over BT…
    • Will try to get loop normals work so far reviewed, and keep working on bin FBX export.

Week 008 - 11/02 to 11/08

Well, one more time turned out to be heavily bugtracker-oriented week… Still managed to start bin FBX exporter work (very simple for now), and also tried to add click-rename in uiList, but no luck so far here (this is a bit tricky to do right).

  • General Development:
    • Usual i18n weekly update.
    • Worked on "edit name" uiList feature.
    • Fixed building BGE with c++ guardedalloc (r61101).

    • Spent some time checking over #37200 armature bone extrusion in orthogonal front view gets unexpected roll values (reassigned to Joshua for check, not a bug actually imho).
Fixed: 9; Closed: 11.
  • Next week:
    • Will keep working over BT (sic).
    • As git is not yet up and running, will leave again loop normals a bit on rest, and keep working on bin FBX export (first step is to get current code design approved by Campbell, before I start adding real data export).

Week 006 & 007 - 10/19 to 11/01

Merged two weeks in one report, as there was the bconf who ate quite a bit of time… As in previous weeks, I spent some time on bug tracker, and finishing rough loop normals first stage, which is now ready for a first quick review (not in details, but on general design & features at least).

  • Game-dev related (Loop Normals, vgroup_modifiers branch):
  • General Development:
    • Usual i18n weekly update.
    • Updated install_deps.sh to use openEXR 2.0.1 (r60953).

    • Fixed (partial, OpenGL part) #37159 Particle Emitter set to not render still appears in 3D view, when display set to rendered only. Emitter also appears in all GL Renders and some F12 renders (r60882) .
    • Fixed #37224 Icons: tiny interface issue with certain DPI settings (r61041).
    • Fixed #37266 Skin modifier can't be copied (patch by Martin Felke, r61042).
Fixed: 5; Closed: 17.
  • Next week:
    • Will keep working over BT.
    • Will probably leave loop normals a bit on rest, and try to get a first working FBX export draft, as it seems quite unlikely Campbell will find time for it any soon.

Week 005 - 10/11 to 10/18

As last week, I kept doing some tracker stuff, but tried to work more over loop normals topic on my vgroup_modifiers branch. Though I did get some things done here (mostly working preview of sharp edges in viewport), I was a bit frustrated by an annoying issue with bmesh and cdlayers…

  • Game-dev related:
    • Committed first part of split normals support in tessellated data (r60744). Still buggy with BMesh, though. :/
    • Committed more tessellated support for split normals (r60799).
    • Committed correct default/update value for new object's split_angle property (r60801).
    • Committed basic split normals shading in viewport (r60802).
    • Spent some time over issue with loop normals and bmesh, with not much luck so far (see also mail http://lists.blender.org/pipermail/bf-committers/2013-October/041968.html).
  • Bug Tracker:
    • BT misc (general check, assign & close work).
    • Fixed #37077 User prefs > Input and Outliner Keymaps mismatch in representation (r60775).
    • Fixed #37085 Hook modifier work when created with Ctrl+H, but not when created via modifier panel (r60777).
    • Fixed #37095 Timeline crash when chose any keying set then press keyframe-insert (r60812, r60813, r2429, r2430).
    • Closed #37054 "Overlay" tab in object and edit mode.
    • Closed #37021 unregister() never called on Run Script and F8.
    • Closed #37068 inverted faces.
    • Closed #37079 Python: overriden context prints out PyContext not found errors.
    • Closed #37096 Can not select bones when in Weight Paint mode.
    • Closed #37126 RGBA is issue.
    • Closed #37135 Weight paint mode, bone selecting is very slow (Linux 64bit).
    • Closed #37140 Dynamic Paint Smudge not working.
    • Closed as TODO #36937 Auto Keyframing in User preferences is not working.
    • Spent some time over #37043 bpy.ops.sequencer.rebuild_proxy() don't release memory, before assigning it to Sergey…
Fixed: 3; Closed: 9.
  • Next week:
    • Will keep working over BT.
    • Will concentrate on loop normals, I really want to understand and fix that bug. Should it be quicker than expected, I’ll try to make tspace and loop normals consistent (currently tspace still uses old vert-or-face normals, which makes loops one pretty useless when using tspace), and maybe make some tests with deeper normal editing (the nor diff idea).
    • Related to above bug: looks like we do not have doc about cd layers handling in bmesh area (still have to get confirmation about that), it looks pretty complex, so I may spend some time writing doc about it, if I can figure how it works!
    • And again, if time allows it, and Campbell has not yet found some to work on first FBX bin exporter, will give it a try (yeah, I know, keep saying that for four weeks now :/).

Week 004 - 10/05 to 10/11

I kept doing some tracker stuff, but also started working over loop normals topic on my vgroup_modifiers branch.

  • General Development:
    • Usual i18n weekly update.
    • Fixed build issue with scons, reported by ebrain on IRC (var declared in an #ifdef DEBUG, but used in an #ifndef NDEBUG, r60579).
    • Fixed wrong setting for scons in install_deps.sh script (r60580).
    • Enhanced python patch to fix encoding issues with embedded python under Windows (http://bugs.python.org/issue16129), as suggested by Brecht.
    • Fixed SSS pressets' buttons not being aligned anymore (reported by DingTo on IRC, r60685).
    • Set up my own valgrind suppression file, and updated wiki doc about it (http://wiki.blender.org/index.php/Dev:Doc/Tools/Debugging/Valgrind), was giving a rather cumbersome/inefficient method…
  • Bug Tracker:
    • BT misc (general check, assign & close work).
    • Fixed #36985 FBX Exporter does not export UVs (r4786).
    • Fixed #36993 Blender 2.69 test build freezes when changing metaball view resolution to less that 0.100 (r60605).

    • Closed #36997 Settings are disabled when i add object (in Object Mode).
    • Closed #37026 Apply location moves the origin of a mesh to the center of the scene.
    • Closed #37020 Blender Doesn't Remember Window Settings/Size (as duplicate of #36707).
Fixed: 5; Closed: 6.
  • Next week:
    • Will keep working over BT, but trying to spend less time over it.
    • Will concentrate on loop normals: first of all finish viewport preview, and keep brainstorming on data model.
    • Again, if time allows it, and Campbell has not yet found some to work on first FBX bin exporter, will give it a try.
