Notes

Papers/Articles - Bin Packing

We're looking for an algorithm for 2D nested bin packing of irregular shapes. Approaches to investigate include simulated annealing, genetic algorithms and lots of heuristics.

  • Also worth to take a look at 1bit bitmap based packing algorithms since with UVs you're dealing with pixel-based data most of the time anyway.

Coding Style

Python coding style checker, IRC snippet:

17:12:46 - howardt: there's a python program that checks if you followed the rules. not sure if it is mentioned on that page.
17:13:15 - howardt: in source/tools, run something like this:
17:13:27 - howardt: python3 tools/blender-dev-tools/check_source/check_style_c.py blender/editors/uvedit
17:13:56 - howardt: i'm not sure if the blender-dev-tools/check_source is in the main blender tree or is a separate git checkout
17:14:22 - howardt: that command checks all the files in the directory named as the last parameter
17:18:17 - howardt: i think there's a python package you may have to install on your computer in order to get that script to work
17:19:41 - howardt: yeah, it is called pygments (a parser)

Faster Builds

To get Blender to build faster (especially faster incremental rebuilds) there is a make lite make target which can be used. This disables installing a lot of dependencies and also build Blender without physics & sims or Cycles rendering, so be aware of that if you intend to work in these areas!

It is mentioned in brief here: https://wiki.blender.org/index.php/Dev:Doc/Building_Blender/Windows/msvc/CMake#Automatic_CMake_Setup

11:59:32 - SaphireS: I see there's a "lite" make target, is that recommended for faster builds? (I'm only working in uvedit area)
12:02:38 - ideasman42: SaphireS, yes, you can use for a lot of development
12:02:57 - ideasman42: OTOH. you can just disable options for your existing build too
12:03:51 - ideasman42: if you already have a dev env setup, disable all WITH_*, except for WITH_PYTHON
12:04:09 - ideasman42: WITH_SYSTEM_* you can leave on too
